Before buying any smartphone, do you usually give it a check as per your needs? A trial run is always the best idea if you wish to encounter no problems with the product during use.&nbsp;Similarly, prior to launching any mobile application (or a website, for that matter), field testing is important. It checks the ability of the application to function under real-life conditions before it is released to the users.



Let’s see how field testing is critical for testing every mobile application today.

<h2 id="h-what-is-field-testing">What is Field Testing?</h2>



Field testing refers to the process of testing and evaluating an application in real-world conditions outside of the controlled development environment. Testers deploy this approach for both web and mobile applications with the aim of gathering real-user feedback and identifying any issues or potential improvements before the official release.



In mobile, it involves deploying the app to actual devices and having users interact with it in their everyday environments. Typically, the testing is done on mobile networks only. It is a type of <a href="https://testsigma.com/mobile-testing">mobile testing</a>.



Field testing checks the app on various devices, operating systems, and network conditions to assess its performance, functionality, usability, and overall user experience. The goal is to uncover issues and collect feedback that went unnoticed during the development and testing phases.



One fascinating aspect of field tests is the discovery of unexpected user behaviors and usage patterns. Despite extensive testing during development, field testing often uncovers unique scenarios that developers may not have anticipated. These scenarios could include different network conditions, diverse device configurations, or user interactions that were not replicated in the testing environment. By conducting field testing, developers gain valuable insights into how their app performs in the hands of real users, allowing them to identify and address any issues or optimizations needed for a better user experience.



<h2 id="h-why-is-field-testing-important">Why is Field Testing Important?</h2>



Field tests are a perfect way of experimenting with your product before launching it to your customer base. The short time window between the final testing and the release date is when the field test is performed. The process allows you to:



<ul><li>Gain access to unhinged feedback from a small portion of users who interact with the application.</li><li>Develop products that are error-free and ready for launch.</li><li>Collect critical data that are essential to improve the application and its features.</li><li>Work on new features and upgrades for the future.</li><li>Use the test data from the users for other purposes, such as sales and marketing.</li></ul>



<h2 id="h-who-does-field-testing">Who Does Field Testing?</h2>



Since field testing is done at the last stage of development, product managers, marketing managers, and the support team takes care of the process. They provide the application access to users and gain maximum insight from their feedback.



<h2 id="h-when-does-field-testing-happen">When Does Field Testing Happen?</h2>



Field testing in software testing occurs at the later stage of application development. It comes even after alpha and beta testing. And because the application is made available to only a few users, field testing is also called a limited release or soft launch. The right hierarchy of testing is given below:



Alpha testing -&gt; Beta testing -&gt; Field testing -&gt; Application launch -&gt; Support



<h2 id="h-field-testing-and-test-automation">Field Testing and Test Automation</h2>



Field testing involves a few users checking out the application before releasing it to all the customers. It’s like ‘playing the field’ before the main game starts. And because users interact with the app on their own, there is no room for automation in this scenario.



However, there might come instances after field testing is complete where you would need automation. That is when you receive feedback from the users, which requires you to address bugs or features that went unnoticed before. Such insights give rise to new test cases, which can be automated using the right tools to save time and cost. And surely, an effective approach here is to go for a test automation tool, such as <a href="https://testsigma.com/" target="_blank" rel="noreferrer noopener">Testsigma</a>, to run all the test cases.



It is a powerful, AI-powered tool that easily supports web and mobile application testing. The simple interface and <a href="https://testsigma.com/blog/the-era-of-low-code-no-code-platforms-what-you-should-know/" target="_blank" rel="noreferrer noopener">no-code testing</a> make the tool a go-to option for less complex tests that do not need many resources, which might often be the case after field testing. Testsigma provides a cloud-based testing platform that supports end-to-end test automation for mobile applications. It allows testers to create and execute test scripts across different devices, operating systems, and network conditions.



 <button class="btn bg-primary cta-btn" style="margin: auto"><a href="https://testsigma.com/signup" target="_blank" rel="noopener noreferrer" style="color:#fff">Automate your tests for web, mobile, desktops and APIs, 10x faster, with Testsigma</a></button> 



For instance, let&#8217;s consider a simple mobile application that involves searching and sorting products as per their category. Clothes go into apparel, laptops and mobiles are under electronics, medicine and household products are under essentials, and so on. With Testsigma, field tests for this application can be automated after you receive suggestions from the limited user base. You can design test scripts to run regression tests and validate the right sorting with their cost and usage.



<h2 id="h-how-to-run-a-field-test">How to Run a Field Test?</h2>



Like other user tests, field testing offers a multi-step approach that includes planning, designing, testing, and analyzing reports. Let’s look at these steps individually.



<ul><li>Planning: Clearly, every process begins with the planning phase. It consists of a simple and concise document outlining the goals, objectives, deadline, authority, and results of the project. This stage involves talking to the stakeholders, project managers, and developers; basically, everyone is involved in the process of creating the document.</li><li>Designing: In the designing phase, the document is shared with the responsible individuals of the teams who would be working on the project. They will understand the task and start developing the application with all the necessary resources.</li><li>Testing: This step comes after the designing/development when testers get involved in the project to validate the application for its authenticity and specifications. They perform their own set of tests, manual or automated, and share the finally passed product which undergoes field testing using a small portion of users.</li><li>Analyzing: The last phase analyzes testers&#8217; results after running the previous step. It includes assessing the success of the test and its implications and making recommendations for improvements, further tests, or next steps.</li></ul>



<h2 id="h-limitations">Limitations </h2>



Field testing has several limitations that should be taken into consideration when planning and interpreting the results. Here are some common limitations associated with field testing:



<ul><li>Field tests can be challenging as it is conducted in real-world environments where conditions can be highly variable.</li><li>Field tests are resource-intensive and time-consuming, requiring a dedicated team of QAs to perform all the steps that include real-world scenarios.</li><li>It can be risky to make the mobile application available to the end-users, however small in portion, without offering them initial guidance about the features and functions of the app.</li><li>For most testers and businesses, procuring multiple devices of varying dimensions and software specifications to execute field testing can be challenging.</li></ul>



It is possible to mitigate all these issues. You need to carefully plan and prioritize field testing efforts from the beginning.



<h2 id="h-examples-of-tests-that-can-be-verified-in-field-test">Examples of Tests that Can Be Verified in Field Test</h2>



Suppose you are building an application that tracks stock prices and allows users to buy/sell them in real time. The functions of the app would include:



<ul><li>giving stock information,</li><li>adding money to the app wallet,</li><li>enabling the buying/selling option within seconds, and</li><li>making all the payments without any interruptions, as stock prices are quite volatile.</li></ul>



Not to mention that hundreds of thousands of users would simultaneously do all of these. Two of the field tests for this type of application would be checking the network and connectivity testing and performance testing.



Test the application&#8217;s performance and behavior for network and connectivity validation under different network conditions, such as 3G, 4G, Wi-Fi, or low signal strength areas. Verify that the application works properly and efficiently handles network interruptions.



For performance, you need to check if the application can withstand certain load/visitor limits. Testers usually do that by hitting the app with huge traffic. In field testing, that can be done by asking users to consistently open the app and perform some activities to see if the application is performing everything properly.



Some other field tests that you can conduct for this application are checking how it affects the battery and power consumption of the mobile and validating if the UI is displaying correctly on different devices with varying dimensions.&nbsp;



<h2 id="h-best-practices">Best Practices</h2>



Let’s look at some of the best practices for field testing that will make it easier for you to deliver an unexceptionally high-quality mobile application to your users:



<ul><li>Select a diverse set of devices representative of your target user base.</li><li>Test the app under various network conditions, including different signal strengths, network speeds (3G, 4G, Wi-Fi), and network providers. This helps assess the app&#8217;s performance and reliability across different connectivity.</li><li>Define specific test scenarios and use cases that cover a wide range of user interactions and workflows.</li><li>Perform field tests after all the <a href="https://testsigma.com/regression-testing" target="_blank" rel="noreferrer noopener">regression tests</a> are complete, and you have a list of <a href="https://testsigma.com/guides/what-is-test-case/">test cases</a> to support your testing process.</li><li>Be detailed and clear while logging the feedback to ensure no communication gap or confusion about how the app works.</li><li>Pay attention to the app&#8217;s impact on device resources such as battery life, CPU usage, memory, and data consumption.</li><li>Lastly, refine and enhance the app using the insights gained from field testing.</li></ul>



<h2 id="h-summary">Summary</h2>



Any product becomes a hit when users accept it and like it. Same with mobile applications. But how do you make sure that users like the final product without releasing it to them? You launch the app for your users. Confused?



Field testing validates a mobile application in real-life conditions by making it available to a few potential customers. It helps product managers and stakeholders to gather critical insight into the functioning of the application before making it public for everyone to use.

<h2 id="h-what-is-a-software-bug">What is a Software Bug?</h2>



Software bugs are errors, flaws, deficiencies, or defects in a computer program or system that cause it to produce an incorrect or unexpected result or to behave in unintended ways.



<h2 id="h-different-types-of-bugs-in-software-testing">Different Types of Bugs in Software Testing:</h2>



Software bugs can be classified into multiple categories based on their nature and impact. Broadly speaking, these categories include Functional Bugs, Logical Bugs, Workflow Bugs, Unit Level Bugs, System-Level Integration Bugs, Out of Bound Bugs, and Security Bugs.



<h3 id="h-1-functional-bugs">1. Functional Bugs</h3>



Functional bugs refer to defects or issues in software applications that affect their intended functionality. These bugs can manifest in various ways, such as incorrect calculations, unexpected behavior, crashes, or unresponsive features. They can arise due to coding errors, inadequate testing, compatibility issues, or external factors like hardware limitations.



For example, for functional testing, let us consider a scenario wherein the user logs into their Testsigma account. The Email field within the login page fails to accept special characters like “@” and “.”, , triggering a functional defect in the form of an error message.



<figure class="wp-block-image"><img src="https://lh6.googleusercontent.com/wGbyDNpHKGBOktYYYq2wMyll0XIcFXfg4LWN_kapKqUJVAXSmn2stEKc7tAad4haOOArZxCRYIrMgg5uXdFlCzVOLUPA40l3j_nEPsfJA6KyhtVztzKvVRDjVz2JfPTWIZ6HiFszuHC9" alt="Functional bug" /></figure>



 <h3 id="h-2-logical-bugs">2. Logical Bugs</h3>



Do you know Logical bugs are common in software development and can be quite challenging to identify and fix? Unlike syntax errors, which are relatively easy to spot due to their violation of the programming language&#8217;s rules, logical bugs occur when the code does not produce the expected output or behavior.



In the image shown below, the user&#8217;s action of clicking on the &#8220;Blog&#8221; page in Testsigma is depicted. It would be considered a logical bug if the user is redirected to the &#8220;Support&#8221; or any other page.



<figure class="wp-block-image"><img src="https://lh4.googleusercontent.com/8VWWdDK-NnRIZnz_fvH_9X8PVMi8ZchO4aDjO2qubY_sn8FRRr9m2OxP93SmN5w2i8Dki2nPqoyeIzp3jjmN-yUYmkn9hJ-Qrv47waMbg8zPTK6oHhEFGFg1X3YQnp6U9SHgc89MCclT" alt="logical bug" /></figure>



 <h3 id="h-3-workflow-bugs">3. Workflow Bugs</h3>



This bug can be a major hindrance to productivity and efficiency in any organization. These bugs refer to glitches, errors, or bottlenecks within a workflow process, causing team members delays, confusion, and frustration.



Let&#8217;s consider an example to explain this concept. Upon accessing the website &#8211; <a href="https://testsigma.com/" target="_blank" rel="noreferrer noopener">Testsigma.com</a> on the below-mentioned page, the user is expected to be redirected to the documents page upon clicking the &#8220;Doc&#8221; icon. However, this expected behavior does not occur. In that case, it can be inferred that a workflow bug exists within the system.



<figure class="wp-block-image"><img src="https://lh5.googleusercontent.com/dwZattff_0AEIj5jppiIfSGzL_degsZmZB3gGrwZnykDYfWGxuOseRip0I4ZJPlO4p9gzMN3pq2LsEKukFNqB9xuH6CgsiVj1DbOuIP4YmDLFSyX2UG1EgtFKk98mgBm9pTaXg4cQ5h2" alt="workflow bug" /></figure>



 <h3 id="h-4-unit-level-bugs">4. Unit Level Bugs</h3>



Unit-level bugs refer to the defects or errors at the smallest testable component of a software system, known as a unit. These units can be functions, methods, classes, or modules. When developers write code, they break it into smaller units to make it more manageable and easier to test.



Explaining a unit-level bug through an example is a simple task. The image shows no action after clicking the &#8220;Schedule a Demo&#8221; button. Based on this observation, it can be concluded that the issue is a unit-level bug, which pertains to a defect that occurs at the smallest unit of code &#8211; a module, function, or statement.



<figure class="wp-block-image"><img src="https://lh3.googleusercontent.com/fbPBDCi5jceOODQXQioHzfyNS2COD3thQLwgN3raQ0KBauLxruHW3zVV4FxxvR7oqd0zgog6k7j99GzzTJj_rgbifo_6yvcLBuQR0c3rXWBHMjNGXWyPKxUS2OCkF8b1cibsiJO-otJq" alt="Unit level bug" /></figure>



 <h3 id="h-5-system-level-integration-bugs">5. System-Level Integration Bugs</h3>



System-level integration bugs refer to the issues that arise when different components or subsystems of a complex system fail to work together seamlessly. These bugs can occur for various reasons, such as incompatible interfaces, module miscommunication, or inadequate testing.



Consider an example scenario &#8211;



Suppose we have a web application with multiple modules like user registration, login,&nbsp; checkout and payment processing. Different teams develop each module, which must be integrated for the application to function correctly. The application throws an error when the user clicks on “Proceed to Payment” &#8211; means the system failed where the checkout was integrated with payment. This will be an example of a system-level integration bug.



<figure class="wp-block-image"><img src="https://lh5.googleusercontent.com/gkAzt_acii0beOnuyoeZ6ZbdmTmvxNQ5TyYZuc89uIp3qT5w7oY_fc502y0co7bmkL9zxGktQ119UnfcVy9FvcsD52XwRLHT-mZggY5Yh0_iiqTj1cJWMSYy-nbiB2GxVcIA8_eLL7L4" alt="system level integration bug" /></figure>



 <h3 id="h-6-out-of-bound-bugs">6. Out of Bound Bugs</h3>



Out Of Bound Bugs occur with logical and arithmetic errors exceeding the allowable boundaries of a specified operation.



Consider the following scenario in which a user attempts to schedule a Demo in Testsigma. Upon navigating to the TimeSlot page, the user incorrectly selects a date one day before the current date, July 18th, 2023. As a result, the Demo gets scheduled for July 17th, 2023, which is outside the acceptable range of dates. This can be categorized as an out-of-bounds bug.



<figure class="wp-block-image"><img src="https://lh5.googleusercontent.com/_g9aj1Y_TfZ3aNgVWjcD442fjWmmbrhmQXeCuU4fx2PlTGOe3HH5nkRv08eGB6cSgdv-HMkDH66Tnqhk3V10Na2fzxtiiXiqXs5fuaDjsDG2e3oRx_wELuhkdw8W16tioQ5kpwD-QO4K" alt="Out of bound bug" /></figure>



 <h3 id="h-7-security-bugs">7. Security Bugs</h3>



These are persistent and concerning issues in the world of technology. These bugs refer to vulnerabilities or flaws in software, hardware, or systems that malicious actors can exploit to gain unauthorized access, steal sensitive information, disrupt services, or cause other harmful consequences.



So, here is an example of a security flaw. Look at the image below where the user enters the wrong combination login on Testsigma login page, it lets the user in! This is a major software flaw because it exposes the site to security risks. This will enable anyone to log in to the application. It&#8217;s a security bug.



<figure class="wp-block-image"><img src="https://lh5.googleusercontent.com/ef6W57VoQG4IXtsuMvJFK094mdCwa8m7lD82gX16rqiePA7fZzEhUAx0dCcs-ikSztVeTPgd2UwRpGJbmfRAaZuR178OvOPoy8UWM9yvf6krzbnKyy8ooPvagntod-G3pGkzTO7pU0-M" alt="Security bugs
" /></figure>

<h2 id="h-how-to-find-underlying-software-bugs">How to Find Underlying Software Bugs?</h2>



Finding underlying software bugs can be a daunting process for developers, but it can be done if it is done systematically. To find the underlying software bug, the following steps should be taken:&nbsp;



<ol><li>Begin bug-hunting via exploration of the features of the software: Test each feature and identify underperforming or unexpected behaviors; for example, within Testsigma Web Application, if we are testing the “login feature” &#8211; test the logging in/out process, and note any errors in the loading/saving/validation of data. </li><li>Carefully study the user interface: Explore every menu, every button, every page, etc., and look for inconsistencies and unexpected features. For example, within if we are testing the registration page for Testsigma application, you need to analyze the user interface for that page and ensure that all input fields are validated correctly. </li><li>Set up test plans: Set up user scenarios for various functions the software should have and thoroughly test each scenario. For example, when testing the registration process in Testsigma Web Application, create a plan to register a user, log out, log in back, and verify the login credentials are correct. </li><li>Make use of existing automation tools. Executing existing automation scripts and verifying if the executables are returning expected output can be immensely helpful in uncovering unknown software bugs. For these, you should use a test automation tool that goes well with your application. Testsigma is a <a href="https://testsigma.com/qa-automation-tools" target="_blank" rel="noreferrer noopener">test automation tool</a> that lets you automate your tests for web, mobile, desktop and APIs, from the same place.

<h2 id="h-what-is-feature-testing">What is Feature Testing?</h2>



Feature testing is essential to the development lifecycle because it helps identify any bugs, errors, or problems that might occur when using a particular feature. Feature Test is important when creating something new. It helps spot any issues that could arise when using a certain feature.&nbsp;



Feature testing is essential in delivering high-quality software. Some examples of tests during feature testing include:



<ul><li>Checking if a button works correctly,&nbsp;</li><li>Verifying data inputs are processed accurately or&nbsp;</li><li>Ensuring that different components interact seamlessly.</li></ul>



Next time you use a feature in an app or website and everything seems to work smoothly, remember that dedicated testers spent time testing that feature. That&#8217;s why you get a seamless user experience.



<h2 id="h-how-feature-tests-work-manual-and-automated">How feature tests work &#8211; Manual and Automated</h2>



Feature tests ensure that an app&#8217;s feature does what it should when it&#8217;s up and running.



Manual testing involves a human tester executing test cases to verify the software&#8217;s functionality. This approach is often used in the early stages of development when the features still need to be fully developed and still need to be stable for automation.&nbsp;



For example, let&#8217;s consider a scenario where we have developed a login feature for a web application. In manual testing, a tester would have a test plan to test the login feature thoroughly. It would include testing the login with valid and invalid credentials, all UI elements, and any other apt test.&nbsp;



<a href="https://testsigma.com/automated-testing" target="_blank" rel="noreferrer noopener">Automated testing</a> involves an automation tool executing test cases to verify the <a href="https://en.wikiversity.org/wiki/Software_functionality" target="_blank" rel="noreferrer noopener">software&#8217;s functionality</a>. The following discussion presents an example of automated feature testing using Testsigma, a no-code test automation tool.&nbsp;



We aim to automate the data-driven functionality in Testsigma, which enables us to input data sets along with the values. First, we give that data to be tested.&nbsp;



The image below shows the test data profile used to run the test case. I have taken the Data Set as Things, and the Values are -The Guide, Gel Pen, and KIA, for example.

Search can be an important functionality for any application that has a good amount of content. For example, for a website, search functionality can allow users to look for specific blog titles, products, features, and more without having to browse through the entire site. Similarly, for a mobile application that hosts content, what would you do if Netflix did not have a search functionality? As search is such an important functionality to have, making sure it works as expected is important too. So, in this blog,&nbsp; we discuss the test cases for search functionality.

<h2 id="h-where-would-you-use-search-functionality">Where Would You Use Search Functionality?</h2>



Any website is vast, made up of web pages, including hundreds of blogs, product pages, product feature pages, guides, documents, resources, and much more. How would you access a particular product feature or a guide page among many such pages? Search functionality is useful in these situations. And as mentioned above, search functionality is also useful in many other places as well, such as OTT platforms, social media platforms, news portals, voice assistant devices like Alexa, and smartphones. Some of the websites also have a search feature with filters to add more options for the users.



Clearly, with requirements at these many places, search functionality is an important aspect of any development process that must receive sufficient attention. And to test this feature, you need a well-laid-out list of test cases, both <a href="https://stackoverflow.com/questions/19355354/positive-test-cases-and-negative-test-cases" target="_blank" rel="noreferrer noopener">positive and negative</a>. Let’s discuss them in detail.



<h2 id="h-positive-test-cases-for-search-functionality">Positive Test Cases for Search Functionality</h2>



For any kind of search functionality, you can create and run the below-mentioned positive test cases. These cases cover different scenarios to verify that the search functionality performs the right operation and delivers accurate results.



<ul><li>Enter a valid search term and expect relevant results to be displayed. Searching for &#8220;cat food&#8221; on an e-commerce website should show a list of cat food products as a result.</li><li>Enter multiple valid search terms and ensure that the search function can handle them appropriately. Searching for &#8220;blue dress&#8221; on a fashion website should show a list of blue dresses.</li><li>Verify that the search function is case-insensitive. Searching for &#8220;apple&#8221; or &#8220;APPLE&#8221; should yield the same results.</li><li>Test if the search function can find exact matches and prioritize them in the search results. Searching for &#8220;iPhone X&#8221; on a mobile phone website should display the exact matching product as the top result.</li><li>Apply additional filters (such as price range, category, or location) along with the search term and verify that the search results are displayed accordingly. Searching for &#8220;laptop&#8221; and applying a filter for &#8220;under $10000&#8221; should display laptops within the specified price range.</li><li>Test the search functionality with many results and verify that the results are displayed on pages with appropriate navigation options. Searching for &#8220;books&#8221; on an online bookstore should display a certain number of books per page and provide a pagination option for browsing through the results.</li><li>See that searching for irrelevant terms or products should show messages like ‘search item not found’ to the users. For instance, searching for ‘phone chargers’ on the grocery application should display such a message.</li></ul>



<h2 id="h-negative-test-cases-for-search-functionality">Negative Test Cases for Search Functionality</h2>



Some of the negative test cases for search functionality help identify potential issues in the search functionality. It ensures that appropriate error handling and user feedback are implemented.



<ul><li>Submitting an empty search term and checking that an appropriate error message is displayed. Leaving the search field blank and clicking on the search button should prompt a message like &#8220;Please enter a search term.&#8221;</li><li>Entering an invalid search term and verifying that the search function handles it properly. Searching for &#8220;@#$%&#8221; or a string of random characters should result in a message like &#8220;No results found&#8221; or &#8220;Invalid search term.&#8221;</li><li>Entering a search term that does not exist in the system. Searching for a specific product or item that is not available in the inventory should display a message like &#8220;No results found&#8221; or &#8220;Item not found.&#8221;</li><li>Apply invalid filters or combinations of filters and verify the search function. Applying a price filter with an unrealistic range (e.g., $10,000,000 &#8211; $1) should display an error message like &#8220;Invalid price range&#8221; or ignore the invalid filter.</li><li>Testing the search functionality with search terms containing special characters. Searching for &#8220;C++&#8221; or &#8220;iPhone 12+&#8221; should not produce any errors or unexpected behavior related to the special characters.</li></ul>



<h2 id="h-test-cases-using-search-operators">Test Cases Using Search Operators</h2>



In some cases, you can use certain operators to refine your search results. Majorly, there are three popular search operators:



<h3 id="h-exact-match-search">Exact match search</h3>



The search engine should return results that contain the exact phrase being searched without any variations or synonyms. For instance, entering the searh query [blue electric car] on Google will list down results that matches exactly with the query. The format for exact match on Google is [search term].



<h3 id="h-phrase-match-search">Phrase match search</h3>



The search engine should return results that contain the phrase in the order given in the search term. Typing “blue electric car” on Google will give results with same phrase along with extra words before or after the keyword. The syntax for phrase match is “search term” on Google.



<h3 id="h-broad-match-search">Broad match search</h3>



The search engine should return results that contain the phrase in any order and returns results if the search term is present in them. This option takes the search term and gives results that remotely similar to it. Entering blue electric car will return car options, blogs, Wikipedia results, and more.



Broad match option takes synonyms and misspellings to show all the results available.



<h2 id="h-advanced-search-functionality">Advanced Search Functionality</h2>



Advanced search filters are mainly a part of online search engines rather than e-commerce websites. For instance, Google and Yahoo! Have certain advanced search filters that you can use to refine your search results. An example of an advanced search filter is making it language specific. Another example could be narrowing down the search results to a specific location or area.



Usually, online shopping sites do not have such advanced filters as normal filters function sufficiently to guide the users in searching.



<h2 id="h-how-to-automate-test-cases-for-search-functionality-explained-with-testsigma">How to Automate Test Cases for Search Functionality? Explained with Testsigma</h2>



To automate search functionality, you can simply choose a test automation tool that supports validating the search functionality without worrying about installing libraries and supportive drivers.



Here, we are demonstrating the automation of a search functionality test case with Testsigma.



Testsigma is a <a href="https://testsigma.com/qa-automation-tools" target="_blank" rel="noreferrer noopener">test automation tool</a> that runs on the cloud and requires no external installation of extra files. It is codeless and AI-based, making it an easy and powerful tool to start your automation journey for any feature of your website or application.



 With Testsigma, there are two ways to write tests &#8211;&nbsp;



<ol><li>&nbsp;Testsigma recorder that turns every interaction with the website into test steps&nbsp;</li><li>Writes your own test cases using NLPs.&nbsp;</li></ol>



 To verify the search functionality on a website, you should run multiple tests &#8211; positive as well negative. For this example, let’s assume that you have to validate the search option present on the blog page of Testsigma.



First, create a test under ‘Test Development’ option in Testsigma tool. 



<figure><img src="https://lh4.googleusercontent.com/lOwUGvyD0z4uFSt4AdzWveu1ZUBSEE_GMok6NQgQhrPDROM93C1P1YrYtX41MwLt3VBOjYKskKrFkZIkl8wi0ePOtB6Nc7CJXRZPayvEYJoUTa5mKdZ0IQiFxZ8W4RtiiZnCxy8Zof34" alt="Test Cases For Search Functionality"></figure>



Create a test case with Name and URL to be tested.



<figure class="wp-block-image"><img src="https://lh5.googleusercontent.com/pn1cEWRpnUn3lowN5RgUO_PWj0BZIO5pJrcNl2f_FDoUD2wJQIaeS_J0Lh-VEseY8Ml_zx-EJ3BGdWD9nyFwSs4JHCnvIohcc-nhxI9G9o2REUmGkqX-yY4yIZtsh8rmSp7kskkB5cXA" alt="Test Cases For Search Functionality"/></figure>



Going with the record approach for test step creation, select the Record option on the top right corner, and perform the below actions:



<ul><li>Identify the search box</li><li>Enter search term into the box</li><li>Click on the search icon or press enter</li><li>Select the first result that comes up</li><li>Verify if the search query is present on the clicked result page</li></ul>



The below image shows how the test steps include recognizing the URL, the search button, and entering the search term in the search field. The results should broadly match the search term entered in the search field. The test cases consist of a verify statement that checks if the search query is present on the blog page.

<h2 id="h-what-is-verification-testing">What Is Verification Testing?</h2>



Verification testing is a process used in software development to ensure two things. One is that a product or system meets its specified requirements. Another is that the product or system adheres to the design and development standards.



Overall, it confirms that the software or product being developed meets the intended purpose and works as intended.



The verification process is typically performed throughout the software development cycle. It involves various testing techniques and tools. These tests ensure that each component of the software functions correctly and meets the expected requirements.



<h2 id="h-what-is-validation-testing">What Is Validation Testing?</h2>



Validation testing involves various testing techniques and tools designed to simulate real-world scenarios. Then, you compare the results to the requirements and specifications. It will ensure that the software meets all necessary criteria.



Any defects or issues identified during validation testing are addressed. The software also gets retested until it meets all requirements. 



Read here &#8211; <a href="https://testsigma.com/blog/validation-testing/" target="_blank" rel="noreferrer noopener">Validation Testing</a>



<h2 id="purpose-of-verification-and-validation">Purpose of Verification and Validation</h2>



So, the whole point of Verification &amp; Validation is to ensure that the product meets all the customer&#8217;s requirements.



&nbsp;Once we get the results, we can show that the product does what it&#8217;s supposed to do and satisfies the needs it was made for.



<h2 id="how-are-verification-and-validation-testing-performed">How are Verification and Validation Testing Performed?</h2>



The following are four commonly utilized methods for software quality assurance:&nbsp;



1. <a href="https://testsigma.com/blog/peer-review-in-software-testing/" target="_blank" rel="noreferrer noopener">Peer Reviews</a>: This involves sharing the software product with individuals and requesting them to review it. The reviewers can provide their observations regarding the product&#8217;s quality and contribute towards identifying any issues.&nbsp;



2. Assessments: A dedicated team inspects the software product and helps identify potential faults and critical areas that require attention.&nbsp;



3. Walkthrough: This method involves demonstrating the software to individuals free to ask questions and express their doubts. This approach can help identify potential issues and provide valuable feedback.&nbsp;



4. Desk&#8211;Checking: This is the process of reviewing a software&#8217;s source code. The development team typically desk-checks a program to ensure the algorithms and code function correctly.



<h2 id="tips-for-successful-verification-and-validation">Tips for Successful Verification and Validation</h2>



Here are some major tips you should consider:



1. Clearly define verification and validation objectives: Set specific goals for the verification and validation process to achieve the desired outcomes.



2. Use appropriate verification methods: Select suitable techniques such as inspections, testing, or simulations to assess the correctness and completeness of the system effectively.



3. Establish a thorough<a href="https://testsigma.com/blog/test-plan/" target="_blank" rel="noreferrer noopener"> test plan</a>: Develop a detailed plan that outlines the scope, schedule, resources, and criteria for evaluating the system&#8217;s performance.



4. Conduct rigorous testing: Execute thorough tests to identify defects, errors, or inconsistencies in the system&#8217;s functionality and ensure it meets all specified requirements.



5. Involve stakeholders throughout the process: Engage relevant stakeholders to gather feedback, address concerns, and validate that the system meets their expectations.



6. Document and track results: Maintain precise records of all verification and validation activities performed, including any issues identified and their resolutions, to ensure traceability and accountability.

<h2 id="h-what-is-a-latent-defect-in-software-testing">What is a Latent Defect in Software Testing?</h2>



Latent defects, also referred to as hidden defects or dormant defects, are flaws within software systems that go unnoticed during the testing phase but surface later in the operational or production environment. These defects remain latent or dormant until specific conditions trigger their occurrence, leading to unexpected behavior, system failures, or suboptimal performance.



Latent defects can be introduced during any phase of the software development life cycle (SDLC), including requirements gathering, design, coding, or even in the testing phase itself. They often arise due to the complexity of software systems, incomplete test coverage, inadequate test scenarios, or limitations in the testing process. Latent defects can lie dormant for a significant period, making them challenging to identify and rectify.



<h2 id="h-what-causes-latent-defects">What causes latent defects?</h2>



Latent defects can be caused by various factors throughout the software development life cycle. Here are some common causes:



<ul><li>Incomplete or Inaccurate Requirements: Latent defects can emerge if the initial requirements gathering phase is not thorough or if there are ambiguities or gaps in the requirements documentation. Misinterpretation or omission of critical requirements can lead to latent defects that remain undetected until later stages.</li></ul>



<ul><li>Inadequate <a href="https://testsigma.com/blog/test-coverage/" target="_blank" rel="noreferrer noopener">Test Coverage</a>: When the testing process does not cover all possible scenarios and edge cases, latent defects may go unnoticed. Limited test coverage can result from time constraints, resource limitations, or insufficient test case design. If specific test scenarios are overlooked, latent defects related to those scenarios may surface in the operational environment.</li></ul>



<ul><li>Insufficient Testing Techniques: The effectiveness of testing techniques used during the software testing phase can impact the detection of latent defects. If the testing team relies solely on functional testing and neglects techniques such as boundary value analysis, <a href="https://testsigma.com/blog/equivalence-partitioning/" target="_blank" rel="noreferrer noopener">equivalence partitioning</a>, or stress testing, latent defects may remain hidden until specific conditions trigger their manifestation.</li></ul>



<ul><li>Environmental Differences: Latent defects can occur when the testing environment differs significantly from the production environment. This could include variations in hardware, software versions, network configurations, or data sets. Differences in these environments may prevent the identification of defects that are only triggered by specific environmental conditions.</li></ul>



<ul><li>Complex Interactions and Dependencies: Modern software systems often have complex architectures with numerous components and dependencies. Latent defects can arise due to unforeseen interactions between these components, leading to unexpected behavior or failures. It can be challenging to anticipate and test all possible combinations and interactions, especially in large-scale systems.</li></ul>



<ul><li>Human Error: Latent defects can also result from human error during the development or testing process. Mistakes in coding, incorrect implementation of requirements, or oversight during test case creation can introduce latent defects that go unnoticed until later stages.</li></ul>



<ul><li>Limited Time and Resources: Pressure to meet deadlines and resource constraints can impact the thoroughness of testing activities. When testing is rushed or given limited resources, the chances of latent defects escaping detection increase.</li></ul>



<h2 id="h-signs-of-latent-defect">&nbsp;Signs of Latent Defect</h2>



Identifying latent defects can be challenging since they remain hidden during the testing phase. However, there are certain signs or indicators that may suggest the presence of latent defects. Here are some common signs to watch out for:



<ul><li>Unexpected System Behavior</li><li>Performance Issues</li><li>Data Inconsistencies</li><li>Uncovered Edge Cases</li><li>User Feedback or Bug Reports</li><li>System Failure or Outages</li><li>Difficulty in Reproducing Issues</li></ul>



By actively monitoring and analyzing system behavior, user feedback, and reported issues, software development teams can improve their chances of uncovering latent defects and implementing necessary fixes to enhance the system&#8217;s stability and performance.



<h2 id="h-latent-defect-example">Latent Defect Example</h2>



Let&#8217;s consider a hypothetical example to better understand latent defects. Imagine a software application used for online banking, where users can transfer funds between accounts. During the testing phase, the testing team successfully conducts various test scenarios, including transferring funds from one account to another within the same bank. All tests pass, and the software is deemed ready for deployment.



However, once the application is live, users begin reporting an issue when attempting to transfer funds to accounts in different banks. The application fails to process these transactions correctly, leading to financial discrepancies. Upon investigation, it is discovered that the testing team did not include test cases covering interbank fund transfers, resulting in an overlooked latent defect.



In this scenario, the latent defect remained dormant until specific conditions were met (interbank transactions), triggering its manifestation. The defect&#8217;s impact on the application&#8217;s functionality was not initially apparent during testing, but it significantly affected the system&#8217;s overall performance and user experience in the production environment.



<h2 id="h-test-automation-to-catch-latent-defects">Test Automation to catch Latent Defects</h2>



<a href="https://testsigma.com/automated-testing" target="_blank" rel="noreferrer noopener">Test automation</a> can play a crucial role in catching latent defects by augmenting the testing process and increasing the chances of defect detection. Here are some ways test automation can help in identifying latent defects:



<ul><li>Improved Test Coverage: Test automation allows for the creation and execution of a larger number of test cases compared to manual testing. Automated tests can cover a wide range of scenarios, including edge cases and complex interactions, which increases the chances of identifying latent defects that may only surface under specific conditions.</li></ul>



<ul><li>Regression Testing: <a href="https://testsigma.com/regression-testing/automated-regression-testing" target="_blank" rel="noreferrer noopener">Automated regression testing</a> helps ensure that previously resolved defects or changes in the codebase have not reintroduced any latent defects. By automating the execution of regression test suites, software development teams can quickly identify any regression-related latent defects that may have been inadvertently introduced during development or maintenance activities.</li></ul>



<ul><li>Consistency and Reproducibility: Automated tests provide consistency and reproducibility, eliminating human error and ensuring that test scenarios are executed in a standardized manner. This allows for better comparison and analysis of test results, making it easier to spot unexpected behavior or inconsistencies that may indicate latent defects.</li></ul>



<ul><li>Execution of Large Data Sets: Automated tests can efficiently handle large data sets and perform data-driven testing. By automating the generation and execution of test cases with various data inputs, it becomes possible to test a broader range of scenarios and identify potential latent defects related to data handling, calculation, or processing.</li></ul>



<ul><li>Stress and Performance Testing: Test automation can facilitate stress testing and performance testing by simulating a high load on the system. By automating the generation of concurrent requests, varying data volumes, or complex workload scenarios, potential performance-related latent defects can be uncovered, such as memory leaks, bottlenecks, or resource limitations.</li></ul>



<ul><li>Continuous Integration and Continuous Testing: Choose test automation tools that integrate seamlessly with your <a href="https://en.wikipedia.org/wiki/Continuous_integration" target="_blank" rel="noreferrer noopener">continuous integration</a> (CI) and <a href="https://testsigma.com/continuous-testing" target="_blank" rel="noreferrer noopener">continuous testing </a>(CT) pipelines. Automated tests can be triggered automatically with each code commit, ensuring that any latent defects introduced during development are identified early on. This allows for faster feedback loops and quicker remediation of defects.</li></ul>



<ul><li>Monitoring and Alerting: Test automation can be combined with monitoring tools to detect and alert on unexpected system behavior or performance degradation in the production environment. By automating the monitoring and analysis of system metrics, logs, or user feedback, latent defects that arise in the operational environment can be identified promptly.</li></ul>

<h2 id="h-conclusion">Conclusion</h2>



In conclusion, latent defects are a type of software defect that remain hidden or dormant during the testing phase but manifest themselves once the software is deployed or used by end-users. These defects can have a significant impact on the functionality, performance, and user experience of the software system.



Identifying latent defects requires thorough requirements analysis, exploratory testing, user acceptance testing, and error analysis. It is important to go beyond scripted test cases and actively explore different scenarios to uncover hidden defects that may not be immediately apparent.



<h2 id="h-frequently-asked-questions">Frequently Asked Questions</h2>



<h3 id="h-1-what-is-the-difference-between-a-defect-and-a-latent-defect">1. What is the difference between a defect and a latent defect?</h3>



The difference between a defect and a latent defect lies in their visibility and timing of detection:



<ul><li>Defect: A defect, also known as a bug or an issue, is a flaw or error in the software that affects its functionality, performance, or behavior. It refers to a deviation from the expected or desired behavior of the software.</li></ul>



<ul><li>Latent Defect: A latent defect, on the other hand, is a specific type of defect that remains hidden or dormant during the testing phase but manifests itself later, often after the software is deployed or used by end-users.&nbsp;</li></ul>



<h3 id="h-2-what-is-an-example-of-a-latent-and-patent-defect">2.&nbsp; What is an example of a latent and patent defect</h3>



Here are examples of a latent defect and a patent defect:



<ul><li>Latent Defect Example:</li></ul>



Consider a software application used for financial calculations. During testing, all the defined test cases pass successfully, and the software is deemed ready for deployment. However, after deployment, it is discovered that under certain specific conditions, such as when the input values exceed a certain threshold, the calculations produce incorrect results. This issue was not detected during testing and remained latent until it manifested in the operational environment.



<ul><li>Patent Defect Example:</li></ul>



In contrast, a patent defect is a defect that is immediately apparent and can be detected during the testing phase. For example, imagine a web application where clicking on a particular button consistently leads to a crash or an error message. This defect is evident during testing as it disrupts the expected flow of the application and can be easily reproduced and observed by testers.
