<h3 id="h-what-is-static-testing"><span id="What_is_static_testing">What is static testing?</span></h3>



<p><a href="https://testsigma.com/blog/static-testing/" target="_blank" rel="noreferrer noopener">Static testing</a> does not involve running the code; it is a static analysis of the source code to find potential issues early in the development process through code reviews, inspections, and the use of static analysis tools.&nbsp;</p>



<h3 id="h-what-is-dynamic-testing"><span id="What_is_dynamic_testing">What is dynamic testing?</span></h3>



<p><a href="https://testsigma.com/blog/dynamic-testing/" target="_blank" rel="noreferrer noopener">Dynamic testing</a> is a reactive technique since it involves executing the code to find real bugs and issues. This includes unit, integration, system, and acceptance testing as well as verifying functionality and performance to verify that defects are realized.</p>



<h2 id="h-static-testing-vs-dynamic-testing-key-differences"><span id="Static_Testing_Vs_Dynamic_Testing_8211_Key_Differences"><strong>Static Testing Vs Dynamic Testing &#8211; Key Differences</strong></span></h2>



<p>Let us look into the major differences between both testing methods:</p>

<p>When choosing between these testing, it is essential to consider the specific requirements and objectives of the <a href="https://testsigma.com/guides/test-process/" target="_blank" rel="noreferrer noopener">testing process</a>. Both approaches have advantages and limitations, so a justification for selecting one over the other depends on various factors.</p>



<p>Static testing involves analyzing code without executing it, while dynamic testing involves running code to identify any issues. The choice between static and dynamic testing largely depends on the desired outcome. Static testing may be the way to go if you’re looking to catch coding errors early and improve code quality.&nbsp;</p>



<p>On the other hand, dynamic testing is likely the better choice if you’re concerned with how a program behaves when running.&nbsp; You could also choose to do both according to the results you are expecting.</p>



<p>I conclude by saying both approaches have their strengths and weaknesses. So, it should be completely a decision based on the project’s specific needs.</p>



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



<p>In summary,&nbsp; both testing techniques play a vital role in software development and complement each other by thoroughly reviewing the software’s quality.</p>

Static Testing Techniques, Tools, Types, and Benefits


<p>We&#8217;re excited to announce our latest release, packed with new features to take your testing to the next level. We built these features with testing efficiency in mind for quality engineering teams delivering quality releases at speed.</p>



<p>Let&#8217;s begin!</p>



<ol><li><strong>Powerful new API testing capabilities<br></strong>.Our brand new API testing interface comes with powerful features that support real-time API response validation, testing of different API methods <strong>(GET, PUT, POST, DELETE, PATCH)</strong>, and data-driven API testing. <a href="https://testsigma.com/automated-api-testing" target="_blank" rel="noreferrer noopener">Learn more</a>.&nbsp;</li></ol>



<ol start="2"><li><strong>Concatenate dynamic test data<br></strong>You can now dynamically generate and use multiple different sets of data and concatenate them with Testsigma&#8217;s test data concatenation feature. It lets you easily concatenate any base strings with dynamic user properties and run the same test for as many iterations as you need. Building dynamic tests saves you time and reduces the risk of errors. <a href="https://testsigma.com/docs/test-data/types/concat/" target="_blank" rel="noreferrer noopener">See documentation</a>.&nbsp;</li></ol>



<ol start="3"><li><strong>Download and white-label PDF reports<br></strong>Generate detailed reports for management reporting or your own audit and analysis for each build. With this feature, you can export reports to PDF, complete with test cases, test steps, and screenshots. Plus, you can include your firm&#8217;s <a href="https://www.goldenflitch.com/blog/how-much-does-logo-design-cost" target="_blank" rel="noreferrer noopener">brand logo</a> to ensure the report follows any copyright and company guidelines. Note: This feature is only available to Enterprise users (<a href="https://testsigma.com/docs/reports/export-reports/export-report-pdf/" target="_blank" rel="noreferrer noopener">See documentation</a>).</li></ol>



<ol start="4"><li><strong>Nested Step Groups<br></strong>Group the test steps that are generally carried out together, and reuse the group everywhere. For instance, in a data-driven test case, you can iterate over user profiles one by one and perform different actions based on the profile type. By creating nested step groups, you can save time and reduce the risk of errors. <a href="https://website.testsigma.com/docs/test-cases/step-types/nested-groups/" target="_blank" rel="noreferrer noopener">Learn more</a></li></ol>



<ol start="5"><li><strong>Disable Test Cases in a Test Plan<br></strong>Sometimes, you know that certain test cases are bound to fail due to known existing bugs. To avoid wasting time on these failures, you can now disable test cases that you don&#8217;t want to run at the moment. This feature allows you to decouple your results from known failures and gives you more control over your testing. <a href="https://testsigma.com/docs/test-management/test-plans/disable-test-cases-in-test-plans/" target="_blank" rel="noreferrer noopener">Know more</a></li></ol>



<ol start="6"><li><strong>Enhance test data mid-execution with new NLP<br></strong>Our new NLP feature lets you write values to test data profile columns during test case execution. For example, if you&#8217;re iterating over a series of SKUs, you can log the price of each SKU from the UI and write it to the desired column for a test data profile. Later, you can use this test data profile in another test case to verify if the prices in another pin code or city are the same. This feature makes it easy to add data from the app being tested to your test data profile or log status for certain actions. <a href="https://testsigma.com/docs/test-data/add-values-to-test-data-profile/" target="_blank" rel="noreferrer noopener">Know more</a></li></ol>

<p><strong>Functional testing</strong> helps verify that the software works as expected and meets user’s expectations. It is a type of black-box testing that involves testing various aspects of the application, such as user interfaces, APIs, databases, and other system components, to validate that they are working as expected. It doesn&#8217;t involve looking into the internal working of software functions &#8211; just observing output on the appropriate input.</p>



<p><strong>Read all about <a href="https://testsigma.com/guides/functional-testing/" target="_blank" rel="noreferrer noopener">Functional Testing</a></strong></p>



<p><strong>Integration testing</strong> is when two or more components are integrated and tested as a whole. It ensures that smaller components are working correctly together after integration and provides an error-free user interface for the end users. It helps to improve the performance and scalability of the software and increase the overall software quality.</p>

<h2 id="functional-testing-vs-integration-testing-purpose"><span id="Functional_Testing_vs_Integration_Testing_8211_Detailed_Comparison"><strong>Functional Testing vs Integration Testing &#8211; Detailed Comparison </strong></span></h2>



<h3 id="functional-testing-vs-integration-testing-purpose"><span id="Purpose"><strong>Purpose</strong></span></h3>



<p id="purpose-of-functional-testing"><strong>Purpose of Functional Testing</strong></p>



<p>Functional testing helps verify that the software meets the functional requirements. It ensures that the software behaves as expected and aligns with the business requirements.&nbsp;</p>



<p>It checks everything like the end-to-end workflows, functionality of the application, APIs, database, client-server communication, security, etc. Every functionality is tested with different inputs, and the test result will be compared with the expected output.</p>



<p id="purpose-of-integration-testing"><strong>Purpose of Integration Testing</strong></p>



<p>Integration testing helps test the interactions between different software modules after they have been individually tested.&nbsp;</p>



<p>The main aim of integration testing is to ensure that the integrated components work together as intended and to identify any issues that might arise due to their interactions. Typically, integration is done after unit testing.&nbsp;</p>



<h3 id="workflow-comparison"><span id="Workflow_Comparison"><strong>Workflow Comparison</strong></span></h3>



<p>Let&#8217;s take a look at the workflow difference between the integration test vs functional test,</p>



<p id="functional-testing-workflow"><strong>Functional Testing Workflow</strong></p>



<ul><li>Understand the software requirements and functional specifications provided by the development team or stakeholders.</li><li>Create test cases that cover different functional aspects of the application and test scenarios.</li><li>Now, create a document for the traceability matrix after designing the test cases.</li><li>Create test data and start executing test cases.</li><li>Once the test is complete, compare the actual result with the expected result to validate if the product works as it is intended to be.</li></ul>



<p id="integration-testing-workflow"><strong>Integration Testing Workflow</strong></p>



<ul><li>Understand the requirements and specifications provided by the developers.</li><li>First, divide the application into smaller modules and understand each module&#8217;s functionality.&nbsp;</li><li>Next, find where you start and finish in each part and create a test plan.&nbsp;</li><li>Choose the best integration testing approach based on the app&#8217;s needs and identify test conditions.</li><li>Then, start to design test cases to perform integration testing and analyze the results.</li></ul>



<h3 id="use-case-comparison"><span id="Use_Case_Comparison"><strong>Use Case Comparison</strong></span></h3>



<p>Functional testing and integration testing are both critical aspects of the software testing process, but they serve different purposes and focus on different aspects of a software application. Let&#8217;s consider different use cases to understand this,</p>



<p id="functional-testing-use-case"><strong>Functional Testing Use Case</strong></p>



<p>Use Case: Consider you are <a href="https://testsigma.com/blog/ecommerce-testing/" target="_blank" rel="noreferrer noopener">testing an e-commerce application</a>&#8216;s shopping cart functionality.</p>



<ul><li><strong>User Scenario:</strong> Add to Cart Functionality</li><li><strong>Test Description:</strong> Test the cart&#8217;s functionality. That is, when a user adds a product to the cart, the cart should be updated with the correct name, price, and quantity of the product.</li><li><strong>Expected Result:</strong> The application should accurately update the cart and show the correct product details.</li></ul>



<p id="integration-testing-use-case"><strong>Integration Testing Use Case</strong></p>



<p>Use Case: Consider an e-commerce website where users can browse products, add them to their cart, and proceed to checkout. The website is made up of several components: a product catalog, a shopping cart, a user authentication system, and a payment gateway.</p>



<ul><li><strong>User Scenario:</strong> Test the interactions between these components to ensure they work as expected.</li><li><strong>Integration Test:</strong> Test the cart module, checkout module, etc. That is, adding multiple products to the cart and verifying the cart&#8217;s accuracy. Next, add a product to the cart, log out, and then log in again to ensure the cart items are retained. Then, add products to the cart, proceed to checkout, and verify that the payment gateway works correctly.</li><li><strong>Expected Outcome:</strong> The user should be able to browse products, add items to the cart, login, proceed to checkout, and complete the payment.</li></ul>



<h3 id="challenges"><span id="Challenges"><strong>Challenges </strong></span></h3>



<p>Let&#8217;s take a look at the challenges between integration testing vs functional testing,</p>



<p id="challenges-of-functional-testing"><strong>Challenges of Functional Testing</strong></p>



<ul><li>Designing comprehensive and effective test cases for all possible functional scenarios can be complex and time-consuming.&nbsp;</li><li>Functional testing can become complex when requirements change frequently, requiring constant updates to test cases and test data.</li><li>Functional changes or bug fixes in one area of the software can unintentionally impact other areas. Ensuring that new functional additions don&#8217;t break existing functionality requires robust regression testing. Get here the Comparison between <a href="https://testsigma.com/blog/regression-testing-vs-integration-testing/" target="_blank" rel="noreferrer noopener">Regression Testing vs Integration Testing</a></li><li>Defining clear test requirements for every change is difficult due to the detailed and measurable information they contain.</li><li>Keeping a simple report to decide whether something works or not with functional tests might not work well. This is because reports are divided based on features and defects.</li><li>It takes a long time to fix recurring issues and to set up the test environment.</li><li>Creating test metrics to analyze and improve applications is challenging due to software complexities and varying test requirements.</li></ul>



<p id="challenges-of-integration-testing"><strong>Challenges of Integration Testing</strong></p>



<ul><li>When you replace mock data with real modules, you might find new bugs.</li><li>It is time-consuming and needs good coding skills to create integration tests because programs and data required for testing are mocked.&nbsp;</li><li>It is difficult to understand the logic because the software code is written by multiple teams separately.</li><li>It is difficult to understand the code because it is written by different teams separately.</li><li>Testing integrated parts of the software is complicated because various things like the database, platform, and software environment affect the tests.</li><li>Choosing the right testing approach can become harder when you have multiple options to consider.</li><li>Integration testing gets even more complex when external features, tools, and libraries from different companies with their own dependencies are involved.</li></ul>



<h2 id="functional-testing-vs-integration-testing-core-differences"><span id="Functional_Testing_Vs_Integration_Testing_Core_Differences"><strong>Functional Testing Vs Integration Testing – Core Differences </strong></span></h2>

Introductory and Essential Performance Testing Guide to the Beginners

Performance Testing | What it is, Types & How to Perform?


<p>An application undergoes testing way more than it goes through the development and modification phases. First, developers perform <a href="https://testsigma.com/blog/unit-testing/" target="_blank" rel="noreferrer noopener">Unit testing</a>. Then after production is complete, QA verifies multiple aspects, including Performance, Functionality, Integration, Regression, UI, and more. Evidently, having a collective of software, test data, test drivers and stubs, and <a href="https://testsigma.com/blog/automation-testing-tools/" target="_blank" rel="noreferrer noopener">testing tools</a> to validate&nbsp;an application under varying conditions will simplify the testing process; this collection is called a Test Harness. Especially, test harness refers to drivers and stubs, which are programs that interact with the application under test (AUT). Often used synonymously with an <a href="https://testsigma.com/blog/test-automation-frameworks/" target="_blank" rel="noreferrer noopener">automated test framework</a>, a Test harness is a group of all the elements, tools, and data you require to check an application under test (AUT) in different situations. We outline this topic in the blog to help you understand why and how test harnesses are imperative for your business.</p>

<h2 id="h-what-is-test-harness"><span id="What_is_Test_Harness"><strong>What is Test Harness?</strong></span></h2>



<div class="wp-block-image"><figure class="aligncenter"><img src="https://images.storychief.com/account_36412/test-harness-image-1_061a27db45fc685c1f2ad9aacdcd572b_2000.jpg" alt="Test harness stages"/><figcaption><a href="https://www.tutorialspoint.com/what-is-a-test-harness-tools-examples" target="_blank" rel="noreferrer noopener nofollow">Test harness stages</a></figcaption></figure></div>



<p>As mentioned earlier, a <a href="https://en.wikipedia.org/wiki/Test_harness" target="_blank" rel="noreferrer noopener">Test harness</a> is a collection of testing tools, test data, software, drivers, and more to facilitate the software test automation process. It consists of all the detailed equipment and elements a test automation process requires. Once the test automation is complete, the behavior and output of the application testing process are monitored. A subsequent report is also generated.</p>



<p>It is an essential part of the <a href="https://testsigma.com/blog/software-testing-strategy/" target="_blank" rel="noreferrer noopener">software testing strategy</a> that assists QAs in testing each application feature in detail. It includes executing automated test cases to generate the output and <a href="https://testsigma.com/reports" target="_blank" rel="noreferrer noopener">reporting</a> them to developers. Then, coders can analyze the reports to identify the issues and perform the necessary fixes.</p>



<h2 id="h-why-use-test-harness"><span id="Why_Use_Test_Harness"><strong>Why Use Test Harness?</strong></span></h2>



<p>The primary reason to use a test harness is that they are external to the AUT. And replicate the resources or elements that are still unavailable in the test environment. For instance, if you have an application with different modules that require connection with other systems, a test harness can help you out. If the external system is not yet available during the development phase, you should create a test harness as a replacement to continue with the testing process.</p>



<p>Another reason is that a&nbsp;test harness consists of the test execution engine and the test script repository. The former is the software that performs the test, and the test script repository is the location to store test scripts and cases. This way, you have all the necessary testing requirements in one place, which are all easily accessible.</p>



<h2 id="h-benefits-of-test-harness"><span id="Benefits_of_Test_Harness"><strong>Benefits of Test Harness</strong></span></h2>



<p>There are numerous benefits to using a test harness for the testing process. We list down a few of them here:</p>



<ul><li>It helps automate the testing process to simplify and improve overall productivity.</li><li>It contains all the necessary tools and data to execute test cases and suites in one place.</li><li>Developers receive a detailed report with all the relevant information to pinpoint the issues found during the automated testing process.</li><li>It helps developers to measure the test coverage at the code level with high accuracy.</li><li>Test harness&nbsp;in software testing helps to simulate and handle complex conditions to support testers in efficiently managing such situations.</li><li>It is instrumental in debugging and enhancing software quality.</li></ul>



<h2 id="h-key-features-of-the-test-harness"><span id="Key_Features_of_the_Test_Harness"><strong>Key Features of the Test Harness</strong></span></h2>



<p>While the benefits of a test harness will aid you in understanding the necessity of the process, the key features will help you find the exact reason why you should opt for a test harness.</p>



<ul><li>Supports automation of tests</li><li>Monitors and record test results</li><li>Provides flexibility and support for debugging</li><li>It helps developers measure the test coverage</li><li>Execute test suites in the right testing framework</li><li>Manage and input data tests in the AUT</li><li>Supports test case optimization</li></ul>



<h2 id="h-when-and-where-to-use-test-harness"><span id="When_and_Where_to_Use_Test_Harness"><strong>When and Where to Use Test Harness?</strong></span></h2>



<p>There are multiple instances where you can use the test harness. But predominantly, there are two major tests that benefit mainly from using a test harness: Automation and Integration testing. Let&#8217;s discuss them one by one.</p>



<h3 id="h-automation-testing"><span id="Automation_Testing">Automation Testing</span></h3>



<p>In automation testing, test harness functions as a framework that consists of test scripts to run different tests and generate reports with the results of all the executions. Developers can analyze the report to identify the issues, if any, and make improvements.</p>



<p>Often, the right approach to automation testing is when there is a need for running repetitive tests, complex test scenarios, smoke testing, data-driven, and performance testing.</p>



<div class="cta-banner-v2">
<div class="title-with-description ">
<p class="title">Here is a guide with in-depth discussions on do&#8217;s and don&#8217;ts of  automated testing.</p>
</div>

</div>



<p>One instance we can talk about is verifying the data before moving it to the testing tool and receiving proper reporting and analytics for the same. Testsigma data management, along with the feature to get the right report and analytics, allows you to add to your test harness system and improve the testing ability multifold.</p>



<h3 id="h-integration-testing"><span id="Integration_Testing">Integration Testing</span></h3>



<p>We know that Integration testing is validating the connection between two sub-systems of an application to check if they are logically working as per the requirement. And In Integration testing, many developers rely on stubs and drivers to complete the system for testing. Stubs/drivers take the place of the missing module to enable testers to continue the testing process. Without them, they would have to wait for developers to finish working on all the modules, integrate them, and then start the testing process. In case you have to combine the homepage with the login page and add a payment gateway, integration testing comes into the picture here.</p>



<p>First, you must logically connect all these separate elements and test the flow of data between them. Perform unit testing on the login page and check if it integrates logically with the payment feature. But if any of these two pages are missing, a part of the test harness can act as a stub or a driver to replace the modules and continue the testing.</p>



<p>Here, the test harness includes all the documents and tools for planning, designing, developing, and using stubs and drivers to perform Integration testing.</p>



<h2 id="h-examples-of-test-harnesses"><span id="Examples_of_Test_Harnesses"><strong>Examples of Test Harnesses</strong></span></h2>



<p>Let’s take some examples of test harnesses. </p>



<p>1. Consider an e-commerce application that offers users décor items. The website&nbsp;consists of several modules: homepage, product pages, cart, Wishlist, and payment gateway, to name a few. You need to test every feature of the site and ensure that no issues slip away. However, it is difficult to perform the entire testing process in one single shot. With Testsigma, you can run the test cases across 3000+ real devices and browsers. Your testers do not need to spend much time writing test cases and maintaining input data. Testsigma allows you no-code testing with test data management options. And you receive reports and analytics documents to share with all your stakeholders. You can also integrate our test automation tool with&nbsp;multiple bug-tracking tools, CI/CD software, and collaboration platforms. And all of these different aspects would come under test harness for this particular testing.</p>



<p>2. Another example is in terms of integration testing, which undertakes two or more elements to make a functioning system. We can take the example of a login page (of the above e-commerce website) that takes the user to a dashboard with their purchase history, settings, notifications, saved addresses, and more. First, you would need to establish a logical connection between all these modules and check how they are linked. Then, you must execute integration tests on all the features. The test harness, in this case, will include all the systems, requirement documents, test scripts, automation tools, and stubs/drivers corresponding to any missing modules.</p>



<p>3. Suppose you are doing Functional testing using Testsigma tool to organize, manage, execute, and monitor the scripts along with handling the test data. For this, the test harness would be Testsigma, test data, test cases, test scripts and their storage location, test results, and elements that compare and monitor test results. And you can handle all these attributes using Testsigma tool easily. </p>



<p>4. For Unit testing, developers execute the testing process on the code or module they worked on. The test harness for Unit testing would include the test code developers create, the tool they use to run the script, and the output they receive.</p>



<h2 id="h-test-harness-vs-test-framework"><span id="Test_Harness_vs_Test_Framework"><strong>Test Harness vs Test Framework</strong></span></h2>


<p style="padding-bottom:30px">While test harness and test framework are usually thought to be similar, they have small, visible differences. Here are some of the clear differences between a test harness and a test framework.</p>


<figure class="wp-block-table"><table><tbody><tr><td><strong>Test Harness</strong></td><td><strong>Test Framework</strong></td></tr><tr><td>It is a collection of drivers and stubs that are a requirement in software testing</td><td>It is a set of procedures, processes, and test environments in the automation testing setting</td></tr><tr><td>Record &amp; Playback testing option is not available</td><td>Record &amp; Playback testing option is available</td></tr><tr><td>Covers all the relevant information for compiling, testing, and software deployment</td><td>It consists of information like test libraries, scripts, tools, test environment, and so on</td></tr><tr><td>Comes in two categories: automation and integration testing</td><td>Comes in multiple testing categories: data-driven, code-based, keyword-driven, hybrid, and more</td></tr><tr><td>It is specific to the testing</td><td>It is a generic process</td></tr><tr><td>Contains a collection of dummy programs to maintain a relation with application under test</td><td>Contains a collection of dummy programs to maintain a relation with application under test&nbsp;<br>Consists of logical concepts, environments, and so to design and run the tests&nbsp;</td></tr></tbody></table></figure>



<br><h2 id="h-wrapping-it-up"><span id="Wrapping_it_up">Wrapping it up!</span></h2>



<p>Testing an application requires data, test scripts, test environments, output recording and analysis, and integrations. And no matter how much you try, you cannot check all the aspects of your software in one shot. Having a test harness helps you to keep a collection of all the necessary features, tools, data, and more to make your testing process smooth and easy to conduct. All you have to do is gather the required materials and use them whenever the situation calls for it.</p>



<p>Your best bet to use a test harness for your software testing purpose is to use tools that support the process. Testsigma is a test automation tool that consists of several features ranging from test data management and <a href="https://testsigma.com/automated-data-driven-testing" target="_blank" rel="noreferrer noopener">data-driven testing</a> to <a href="https://testsigma.com/regression-testing/automated-regression-testing-tool" target="_blank" rel="noreferrer noopener">regression testing</a> and report and analytics, which are all the essential parts of a test harness.

<p>A test harness is used in two places for software testing: Automation testing and Integration testing. In automation testing, it is used for running test scripts and storing test data. In integration testing, the test harness uses stubs and drivers to replace missing modules.</p>


Test Harness in Software Testing Usage, Examples, and Benefits

Test Harness in Software Testing | Usage, Examples, & Benefits


<p>An application is a collection of several components functioning together to meet user requirements. APIs, servers, web services, databases, and more are intertwined under one roof to build software that does what you want it to do. For instance, your favorite e-commerce store has UI elements, cart and Wishlist functionality, secure payment option, rewards, login, and many more systems running together to improve your shopping experience. These separate modules communicate through an interface. And for flawless interaction, Interface testing is critical because any type of error in the interface can lead to&nbsp;system issues.</p>



<p>Understandably, Interface testing is an essential part of your test planning that must not be skipped. And because it requires a clear knowledge of different components and the need to review data transfer between them, you would also need an elaborate guide on how to perform Interface Testing.</p>



<p>We bring that one guide to you.</p>

<h2 id="what-is-interface-testing"><span id="What_is_Interface_Testing"><strong>What is Interface Testing?</strong></span></h2>



<p>Interface testing is a type of software testing that verifies the interaction between two separate systems of an application. It is a medium that helps components communicate with each other. Usually, it can be in the form of API, UI, servers, graphics, and more. It uses specific commands, messages, and data transfer techniques to act as a connection between the user and the application.</p>



<p>Keep in mind that Interface testing does not validate the functioning of a single component. It only checks if two interfacing systems communicate properly for the software to work as per requirements. If any conflict or issue arises during the testing phase, it is dealt with by the developers.</p>



<h2 id="h-advantages-of-interface-testing"><span id="Advantages_of_Interface_Testing"><strong>Advantages of Interface Testing</strong></span></h2>



<p>There are a few advantages of Interface testing:</p>



<ul><li>An easy-to-understand and use UI decreases the learning for the users to use the application</li><li>Interface testing increases the application’s demand in the market due to it having a stable design and un-complex GUI</li><li>It helps get a grip on what users expect from the application and modify the interface according to that knowledge</li><li>Interface testing improves overall customer satisfaction and makes for an effective application with the potential to gather more users.</li></ul>



<h2 id="h-how-to-perform-interface-testing"><span id="How_to_Perform_Interface_Testing"><strong>How to Perform Interface Testing?</strong></span></h2>



<p>Primarily, Interface testing is for two systems of an application that have connections with each other to ensure the proper functioning of the application. It consists of two major sections:</p>



<ul><li>The interface between the web server and the <a href="https://en.wikipedia.org/wiki/Application_server" target="_blank" rel="noreferrer noopener">application server</a></li><li>The interface between the application server and the database server</li></ul>



<p>It is necessary to check for the interfaces mentioned above to :</p>



<ul><li>That these servers are running properly</li><li>The servers have the right error handling capability, along with the option to return an error message for queries made by the application</li><li>If outcome is proper if/when the connection gets severed due to any problem</li></ul>



<h2 id="h-types-of-interface-testing-with-examples"><span id="Types_of_Interface_Testing_with_Examples"><strong>Types of Interface Testing with Examples</strong></span></h2>



<p>We know that Interface testing checks for connections between two systems in a software. And you can do that by performing various types of Interface testing that we have discussed below:</p>



<h3 id="h-workflow-testing"><span id="Workflow_Testing">Workflow Testing</span></h3>



<p>As per the name, Workflow testing checks for the end-to-end working of the application to validate proper data transfer. The goal is to ensure that the system functions as per the user expectations. Its purpose is to verify if the software workflow is as per the business process, which includes executing a series of steps to see if information/data workflow is proper.</p>



<p>An example of Workflow testing is verifying the transition from signing up and then logging into the application with a valid ID. This process validates the flow between two pages and functionalities using the right data. Even negative data sets test if the workflow rejects the wrong information in such a case.</p>



<h3 id="h-security-testing"><span id="Security_Testing">Security Testing</span></h3>



<p>This type of testing is to understand the security lapses in software to identify possible vulnerabilities that hackers can exploit. It is critical to check the safety of the data/information flow from one system to another. For instance, a loophole on the signup page can compromise the confidential data of every user of the application.</p>



<p>Here, testing of the interface is done through processes such as Penetration testing and access-control testing. An example would be to check only a user that has access is able to login. Any other attempts with invalid data should not be allowed. Here, testers also try to test the robustness of the system against possible hacking attempts.</p>



<h3 id="h-functional-testing"><span id="Functional_Testing">Functional Testing</span></h3>



<p>This testing approach undertakes to verify all the functional aspects of an application. In simple words, functional testing takes care of every small part of the application which has a certain function. Like ‘Forgot Password,’ drop-down menus, images/vidoes, signup/sign-in, search, and much more come under functional testing. It checks for error-free data transfer between different modules. Most often than not, functional testing comes under the black box testing technique, as testers do not access the source code.</p>



<p>An example of functional testing is checking for a return order window and seeing if it works for users as intended for an e-commerce app. Other examples would include verifying the drop-down menus, website clicks, right link placements, and search showing the right results.</p>



<h3 id="h-load-testing"><span id="Load_Testing">Load Testing</span></h3>



<p>This testing type validates how much load/traffic an application can withstand before it crashes down due to heavy influx. The idea is to determine the threshold of the software as in, how many users maximum, can access it at one time, without it breaking. </p>



<p>One example of load testing is checking the application’s ability to handle heavy traffic by hitting the server multiple times.</p>



<h3 id="h-error-detection"><span id="Error-detection">Error-detection</span></h3>



<p>Often, code defects are the reason behind any runtime error. Various tools such as debuggers and profilers are useful to detect runtime errors.</p>



<p>An example of runtime error detection is looking for any possible issues while logging into an application. Another example would be to check if there are any broken elements or click issues on the screen after you open an app on your phone.</p>



<h2 id="h-interface-testing-best-practices"><span id="Interface_Testing_Best_Practices"><strong>Interface Testing Best Practices</strong></span></h2>



<p>You can perform Interface testing in two ways: Bottom-up and Top-down approach. For a better understanding of what these options are and how they function, you can read our <a href="https://testsigma.com/blog/difference-between-top-down-and-bottom-up-integration-testing/" target="_blank" rel="noreferrer noopener">blog</a>.</p>



<p>But despite your choice of one of these two approaches, there are a few best practices that you must follow as a tester to ensure that the application interface is working as per expectations.</p>



<h3 id="h-understand-and-define-your-requirements"><span id="Understand_and_Define_Your_Requirements">Understand and Define Your Requirements</span></h3>



<p>Before you start any project, it is advisable to accurately understand the requirements and document them to avoid missing out on critical points. Similarly, before conducting Interface testing, testers should lay out the testing requirements to build test cases on the same &#8211; positive and negative.</p>



<h3 id="h-write-relevant-test-cases"><span id="Write_Relevant_Test_Cases">Write Relevant Test Cases</span></h3>



<p>Running test cases manually is a laborious task. It is time-consuming and asks for more than just a keen eye. It requires patience, the right knowledge about the application, and sufficient resources to manually perform all the testing activities. That is why creating test cases that are relevant to your software will ensure that you don’t waste time executing something that does not apply to you.</p>



<h3 id="h-build-a-test-data-set"><span id="Build_a_Test_Data_Set">Build a Test Data Set</span></h3>



<p>Before you design and execute the test cases, create a set of test data that will fuel your testing efforts. And make sure to add all the information for the data to mimic real-life scenarios, so you can check if your application is user-ready or not.</p>



<h3 id="h-check-on-different-platforms"><span id="Check_on_Different_Platforms">Check on Different Platforms</span></h3>



<p>Different devices have differing resolutions, user-friendliness, and size; it only makes sense to run Interface testing on multiple platforms to validate the overall intuitiveness of your software for easy usage.</p>



<h3 id="h-document-clearly"><span id="Document_Clearly">Document Clearly</span></h3>



<p>Do not skip or forget the documentation part. Record every test run and result so you can use it later to troubleshoot any bugs.</p>



<h3 id="h-use-a-testing-framework-for-the-automation-of-interface-testing"><span id="Use_a_Testing_Framework_for_the_Automation_of_Interface_Testing">Use a Testing Framework for the Automation of Interface Testing</span></h3>



<p>Running Interface testing on several devices with different test data sets can be time-consuming. The process can become redundant, and as more features get added, the test execution will require more resources too. With the use of a test framework, testers can automate these interface tests. Automating these tests helps save time and effort that can be used in other testing activities.</p>

<h3 id="h-postman"><span id="Postman">Postman</span></h3>



<p>Although Postman is an <a href="https://testsigma.com/api-testing-tools" target="_blank" rel="noreferrer noopener">API testing tool</a>, it still is accessible to run functionality, performance, security, and integrity testing using API requests. All of these are the type of testing that comes under the interface of an application.</p>



<p>Using API calls, you can check the performance of the software based on its time to receive data from the server. For security, testers can use HTTPS through API requests. Even functional and integrity testing are possible. You can check the former by verifying server uptime, page tags and structure, and page headers. Integrity testing checks if the flow of data to and from your page is from verified sources. You can do it by verifying the validity of your webpage links. You can read more about it&nbsp;<a href="https://medium.com/better-practices/ui-testing-with-postman-df713eb9788c" target="_blank" rel="noreferrer noopener nofollow">here</a>.</p>



<h3 id="h-soapui"><span id="SoapUI">SoapUI</span></h3>



<p>Another API testing tool that supports entire functional testing as well as SoapUI. It supports Data-driven testing where you can pass the data in CSV or Excel format. As per your requirement, you can easily execute security and load testing as well, similar to what we mentioned for Postman. Overall, Interface testing is possible with SoapUI as it contains almost all types of website interfaces to run the test cases.</p>



<p>You can explore many other UI testing tools that will automate your Interface testing journey to ensure your application is user-friendly and easy to use.</p>



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



<p>No application is ready for users and market release if the interface check is still pending. Before customers understand the background of your software, they look at its interface and learn the functionality. And if the basics are not working properly, your application is doomed to a failed announcement.</p>



<p>But the solution comes in the form of Interface testing that consists of many different testing types to ensure that your complete application is working as per expectations. We list down why you must go for testing the interface (in the form of advantages) and tools that you can use for your business/project. And if you want a few examples, they are also present for you to understand the concept better.</p>

<p>Interface testing pertains to checking the communication between two sub-systems or components. For instance, UI is the interface between users and the application. And API is the interface between the backend and the application. <a href="https://testsigma.com/blog/integration-testing-types/" target="_blank" rel="noreferrer noopener">Integration testing</a> checks how two or more modules of the application integrate and transfer data among themselves.</p>
