<h2 id="what-is-self-healing-test-automation">What is Self Healing Test Automation?</h2>



Self healing test automation is the solution to resolve key issues that arise due to changes to the properties of the object. There are several ways for a program to identify web elements, some of which are using Name, ID, XPath, and CSS elements. When these attributes change or break, test scripts fail, leading to the collapse of the complete test case.



Self healing empowers teams to adopt a Shift Left approach in the Agile methodology. Not only does it make the testing process efficient, but it also allows for an increase in productivity and faster delivery. Many open-source and commercial tools are available in the market that support self healing test automation using Machine Learning and Artificial Intelligence (AI).



Testsigma is one such open-source test automation tool that uses AI to detect issues and fix them automatically. This complete guide sheds light on Testsigma and its ability as a self healing test automation tool.



<h2 id="why-is-self-healing-automation-important">Why is Self Healing Automation Important?</h2>



Many reasons come to mind when discussing the importance of self healing automation. When test automation is truly making a difference by automating repetitive tasks, the idea is to evolve further to automate core decision-making activities. This will truly enable touchless testing in the coming future.



Here are some of the foundational reasons that make self healing test automation important:



<ul><li>It prevents test flakiness from offering better visibility into how stable the tests are</li><li>Self-healing offers improved efficiency and overall software performance and stability</li><li>You can also increase <a href="https://testsigma.com/blog/code-coverage-vs-test-coverage/" target="_blank" rel="noreferrer noopener">test coverage</a> by reducing redundant code</li><li>Self-healing expediates the testing process, all the while providing valuable insights into application issues and component performance</li><li>There will be fewer failed test cases as the object locator will update automatically</li><li>It saves time and provides increased efficiency by handling several tedious and manual efforts.</li></ul>



<h2 id="the-self-healing-mechanism">The Self Healing Mechanism</h2>



Every test case you run depends on the web element you are verifying. Every web element corresponds to a locator, usually name, id, Xpath, and type, to run test steps successfully. And it is certain that the application under test will undergo continuous modification, which will result in a change of the elements. So, the next time you run the same test again, it will result in failure because of a mismatch of UI. Unless you choose a self-healing mechanism, your pre-designed test cases are bound to fail.



Automation frameworks build the self-healing capability as a smart and automatic feature to ease the tasks of testing teams. The <a href="https://testsigma.com/blog/automation-testing-tools/" target="_blank" rel="noreferrer noopener">test automation tool</a> will apply the new object’s locator to avoid failed test cases. This approach ensures that the entire script stays updated with every change made to the product’s design.



<h2 id="self-healing-in-testsigma">Self Healing in Testsigma</h2>



The number of changes in the testing code is proportional to the changes that the developer makes in the application. For example, if ‘id’ or ‘class’ attributes of an element on a web page is changed by the developer, then the existing automated test script needs also be changed. This may sound simple, but if there are many such changes in the application, this takes a lot of time and effort for the testers to modify tests and run them.



This is where the AI-driven approach of <a href="https://testsigma.com/" target="_blank" rel="noreferrer noopener">Testsigma</a> comes to help.



The AI detects abnormalities in the existing code and automatically fixes them without human intervention. Self-Healing in Testsigma is done with the help of AI algorithms that automatically fix changes made to the source code and prevent tests from failing.



<h2 id="how-self-healing-test-works-in-testsigma">How Self Healing Test Works in Testsigma?</h2>



Testsigma’s AI is smart enough to locate the element despite the change in the attribute and modify it to match the change made in the source code; tests without Self-Healing fail in such cases.



Let’s look at how Testsigma handles auto-healing within the tool.



The first step is to enable the auto-healing option for the future test cases to automatically reform itself when any element changes. For this, go to Settings &gt; Preferences and enable the toggle on Auto Healing widget.&nbsp;



<div style="height:23px" aria-hidden="true" class="wp-block-spacer"></div>



<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/QeHb4UF0Zi_e49BpRMd0QUmafLdf8gpLkgMuljYUr1JyitOHyx_bzO7msar2MN4ivCMB6hNrNB_W8tftGk1MGaWxwoThkmH0u11-TqCGaRVWyzVXVvngxP0WyKhUWE769Zwh2lHrvZA0E1YC1du7Nqg" alt="1.Testsigma Self Healing Test " /></figure>



<div style="height:25px" aria-hidden="true" class="wp-block-spacer"></div>



From now on, if a UI element identifier gets updated, the tool will automatically detect and correct the change in any test case that element appears.



Consider that the login button identifier is changed on the <a href="https://simply-travel.testsigma.com/.">Simply Travel page</a> from //BUTTON[@id=&#8217;login&#8217;] to //BUTTON[@id=&#8217;login-popUp&#8217;]. With the Auto Healing feature enabled, the test lab will successfully locate the element with the new XPATH.



Click on the test step which deals with the auto healed element and click on the Auto Heal option shown on the down-right side.



<figure class="wp-block-image"><img src="https://lh7-us.googleusercontent.com/ge3wLUz2oGQa8DAj1jIyWp12caK2vXa68HlIxBJ1odO20vITDwbaTlAm3yVE9T7hF168NmOzdZJG5cN-nOqX8pRcJ4vXDkpnGy-QbY2glqAIhM1OEFkXX-CMpPM3iaGJ-hX1kuYTQQswqw1tU-3YTRE" alt="2.Testsigma Self Healing Test " /></figure>



<div style="height:20px" aria-hidden="true" class="wp-block-spacer"></div>



This action will open a window displaying the auto healed element and the new XPATH. Basically, you will have access to all the details of auto healing instances present in the test case.



<div style="height:17px" aria-hidden="true" class="wp-block-spacer"></div>



<figure class="wp-block-image is-resized"><img loading="lazy" src="https://lh7-us.googleusercontent.com/4IPI-2PUnzu6vaeSJ3a8xVabDsHpbUXcSKppPsYupj2fwHpGaSOFz3OeaSJr_gMz0nvFuKQpLcRFtekERAWnmxUBsDOaaeKH2nKrwweWa1K9EfQ4vIgPMpz39C4TdJ59QXSbnmP1WgMmXsfPpojS3Bg" alt="3.Testsigma Self Healing Test " width="840" height="593" /></figure>

Self Healing Test Automation | Tests that do Not Require Maintenance

Selenium team has added Selenium 4.0 Alpha to <a href="https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java">mvnrepository</a> two weeks back(24th April) and has created a buzz in the Automation QA Community. 



The QA fraternity has been eagerly waiting for one or more features proposed in this release. The most significant of them would be the <a href="https://www.w3.org/TR/webdriver1/">W3C Standardization</a>. It would make the Framework much more stable and reduce some of the compatibility issues across different Web Browsers. 



Another beginner-friendly change that is coming with this major release is updated Documentation.&nbsp;After version 2,&nbsp;Selenium Documentation had not been thoroughly updated. The updated documentation would help beginners, as well as the experienced, immensely. We also hope some of the drawbacks in the article&nbsp;<a rel="noreferrer noopener" href="https://testsigma.com/blog/selenium-automation-testing-pros-cons/" target="_blank">Pros and Cons of Selenium as an Automation Testing tool</a>&nbsp;will be handled by Selenium 4.



Let us look at some of the prominent changes that we can expect in Selenium 4. And if you dig in at the right place, you can see the complete list of changes in CHANGELOG or CHANGES file &#8211; <a href="https://github.com/SeleniumHQ/selenium">Selenium Github Repo</a> 



Note: This is not a complete list and I have deliberately omitted many of the underlying implementation and architectural changes that a regular QA Automation guy like me wouldn’t have to deal with on a daily basis 😀

<h2 id="architectural-changes">Architectural Changes</h2>



<h3 id="1-now-using-w3c-protocol-for-browser-driver-communications">1. Now using W3C Protocol for Browser-driver Communications</h3>



The earlier versions of Selenium used JSON wire protocol which required encoding and decoding of the API. Whereas, Selenium 4 will now use a standard W3C Protocol to communicate between the driver and the browser. The advantage is that W3C protocol doesn’t require encoding or decoding the API and the tests will be able to directly communicate with the Browser.



<h3 id="2-compliant-with-w3c-webdriver-specifications">2. Compliant with&nbsp;W3C WebDriver Specifications</h3>



Selenium 4 will be entirely compliant with W3C WebDriver standards and this will include the documentation as well. So, the updated documentation will cover detailed instructions for usage.



Also, The actions API has been revamped&nbsp;to conform with the WebDriver Spec.



<h3 id="3-removed-support-for-few-browsers">3. Removed support for few Browsers</h3>



The team will remove native support for&nbsp;Opera&nbsp;and&nbsp;PhantomJS&nbsp;going forward. Still, the users who need to test Opera can rely on Chrome since Opera is based on Chromium(which Chrome is forked from) and for PhantomJS users can use <a rel="noreferrer noopener" aria-label="The team will remove native support for&nbsp;Opera&nbsp;and&nbsp;PhantomJS.

<h2 id="standardized-documentation">Standardized Documentation</h2>



The main problem which most Selenium users face is that there is no proper and updated documentation for Selenium. The Selenium team has not updated the documentation since Selenium 2.0. With Selenium 4, they have updated Selenium’s official documentation to explain the latest changes.







<h2 id="footnote">Footnote</h2>



While it&#8217;s great to see the improvements that are expected to be covered in Selenium 4, it would be a hassle for small and medium-sized teams to read through the API docs, analyze the changes, and rectify the tests broken by the updates due to the considerable changes. 



Many of the above-discussed changes have already been implemented by test automation tools like <a href="https://testsigma.com" target="_blank" rel="noreferrer noopener" aria-label="Many of the above-discussed changes have already been implemented by test automation tools like Testsigma.

Selenium 4.0(alpha) – What Test Automation Engineers can expect!

Loops are one of the most helpful features for software testers. They allow testers to run tests on multiple iterations quickly and easily. Loop testing is a white-box testing technique that focuses on the behavior of a program when it executes loops. 



Loop testing, also known as Iteration testing, is an integral part of software development and debugging which developers actively carry out. The primary purpose of this testing is to ensure that the looping construct works as expected and produces the correct results when executed.



When speaking about a &#8216;For Loop&#8217;, it&#8217;s a way to repeat instructions multiple times with different values, so you don&#8217;t have to do the same thing repeatedly. This helps make complex automation tasks more manageable. This blog will look at how to get the most out of loop testing using Testsigma.

<h2 id="introduction-what-is-loop-testing">Introduction: What is Loop Testing?</h2>



Have you ever wondered what loop testing is and how it can be used to improve the quality of your software?



Loop testing identifies and corrects errors in loops, detects and fixes loop-related issues, and ensures that the code is functioning as expected. It checks whether the program behaves as expected when executing loops and if there are any errors in the loop structure. So this is more helpful in identifying any potential problems in the code and ensuring that it runs smoothly. So if you want to ensure your software is up to scratch, then loop testing should be on your list!



By performing this testing, developers can ensure that their programs run smoothly and efficiently. It can identify opportunities to enhance code efficiency by locating areas that can be improved or optimized. This helps to improve the overall performance of a program.



<h2 id="objectives-of-loop-testing">Objectives of Loop Testing</h2>



Loop testing can help improve the software&#8217;s overall quality and reduce the chances of unexpected and costly errors. Here are some notable points you should not miss:



<ul><li>Make sure all the loops in the code are tested to make sure they work and run correctly.</li><li>See if the loops end when they&#8217;re supposed to or if they keep going forever. Check that the loops aren&#8217;t too slow or too fast and stay within acceptable limits.</li><li>Make sure any changes don&#8217;t cause new issues with other parts of the code.</li><li>Look for mistakes in its work, like wrong conditions or incorrect settings inside the loop body.</li><li>Double-check that there&#8217;s no extra code inside that could slow it down and lead to unexpected results.</li><li>Check that each exit point from a loop is handled correctly and nothing is lost while running it.</li><li>To verify that all data types used inside a loop are valid and compatible with each other, thus avoiding any type conversion errors or data loss due to incompatible types being used together in a single expression inside a loop body</li></ul>



<h2 id="types-of-loop-testing-in-testsigma">Types of Loop Testing in Testsigma</h2>



There are 2 types of loops in Testsigma:



<h3 id="for-loop-testing">For-Loop Testing:</h3>



This type of loop testing checks the functionality of a loop that iterates through the elements in a list or array. It is mainly used to check the functionality of a loop that executes a set of instructions until a specific condition is met. It can also be used to check if the loop works as expected when the condition is not met. Also, It can be used to test if the loop properly stops executing when the condition is not satisfied.



<h3 id="while-loop-testing">While-Loop Testing:</h3>



This type of loop testing checks a loop&#8217;s functionality to execute a set of codes until a specific condition is met. While-loop testing can also be used to check if the loop works correctly when an exception occurs, or an error occurs during execution. Finally, while-loop testing can verify that the loop works correctly under different conditions, such as varying data types and lengths of data elements.



<h2 id="how-to-do-loop-testing-in-testsigma">How to do Loop testing in Testsigma?</h2>



Loop testing in Testsigma is a form of automation that enables you to execute a test case multiple times with different data sets. In Testsigma, you can find the loop function in the change step option in the corresponding test case step. 



For Loop&#8217; is an incredibly versatile and powerful tool used in programming. The loop can be configured to iterate over a set number of times or until a specific condition is met. 



In addition, &#8216;For Loops&#8217; can also be nested within each other, allowing developers to create complex automation sequences with minimal effort. 



Furthermore, this looping structure is advantageous when dealing with large datasets as it allows the same instruction to be applied to multiple items simultaneously. This helps reduce development time and increases efficiency by eliminating the need to process every item manually.



Here you will learn the step-by-step process carried out in Testsigma-For Loop function.



<h2 id="for-loop-example">For Loop Example</h2>



Let us start the Test Case with a simple Go to step. As the next test step, select the Test Step Type as &#8220;For Loop&#8221; to add For loop in the next Test Step.

Loop Testing: An Introduction to ‘For Loop’ in Testsigma

Element Locators | How to do it Using Chrome Extension?

In the field of software testing, speed and efficiency are critical elements that can have a significant impact on project success. Parallel testing is an efficient approach to shorten testing cycles and reduce product time-to-market. In this article, we&#8217;ll look at parallel test execution and how to conduct in Testsigma, a cloud-based test automation tool. We will also review the advantages of parallel testing and how it may help improve your software products&#8217; overall quality.



<div id="toc_container" class="no_bullets">Table Of Contents<ul class="toc_list"><li><a href="#What_is_Parallel_Testing">1 What is Parallel Testing?</a><ul><li><a href="#Why_its_Important">1.1 Why its Important?</a></li><li><a href="#Benefits">1.2 Benefits</a></li></ul></li><li><a href="#How_do_you_Conduct_a_Parallel_Test_Execution">2 How do you Conduct a Parallel Test Execution?</a></li><li><a href="#Creating_Parallel_Testing_in_Testsigma">3 Creating Parallel Testing in Testsigma</a></li><li><a href="#Parallel_Test_Execution_in_Testsigma">4 Parallel Test Execution in Testsigma</a></li><li><a href="#Conclusion">5 Conclusion</a></li></ul></div>
<h2 id="what-is-parallel-testing">What is Parallel Testing?</h2>



With Parallel Testing, automated tests can be run in parallel or concurrently across various <a href="https://testsigma.com/blog/test-environment/" target="_blank" rel="noreferrer noopener">test environments</a> of different device/browser/Operating System versions and their combinations. Hence, more tests are run simultaneously, reducing the execution time by many folds.



Less execution time implies less wait and fast build releases, thus reducing the required testing time!



If you are short of the hardware and plan to run the <a href="https://testsigma.com/blog/what-makes-device-farms-so-crucial-for-software-testing/" target="_blank" rel="noreferrer noopener">tests on Cloud-based device farms</a> such as Saucelabs or BrowserStack, that adds another layer of complexity.



Testsigma allows you to run multiple tests in parallel on real test environments. Testsigma manages and maintains a massive device cloud to ensure that your app works fine on all browsers of different versions, even just-released versions, and also on your local devices if the local test devices of your application are not publicly accessible or if you do not wish to execute tests on cloud devices.



<h3 id="why-its-important">Why its Important?</h3>



Parallel testing is significant in <a href="https://testsigma.com/blog/v-model-in-software-development-life-cycle/" target="_blank" rel="noreferrer noopener">software development</a> because it enables faster and more efficient application testing. By running many tests concurrently, developers can detect problems and issues in less time and with fewer resources.



Following are some of the reasons why parallel testing is performed:



<ul><li>Faster test execution: Parallel testing allows several test cases to be executed simultaneously, considerably reducing testing time.</li><li>Improved <a href="https://testsigma.com/blog/test-coverage/" target="_blank" rel="noreferrer noopener">test coverage</a>: By using parallel testing in software testing, developers may test a broader range of scenarios in less time, which can assist find flaws that would otherwise go undetected.</li><li>Increased accuracy: Conducting tests in parallel can assist to reduce the risk of false positives or false negatives by verifying the same functionality from several perspectives.</li><li>Scalability: Parallel testing may easily scale to meet the needs of larger projects or applications, enabling faster and more efficient testing as the project&#8217;s scope expands.</li><li>Cost savings: Because parallel testing reduces the time and resources necessary for testing, it can assist to cut the overall cost of software development and enhance ROI.</li></ul>

<h2 id="how-do-you-conduct-a-parallel-test-execution">How do you Conduct a Parallel Test Execution?</h2>



Parallel testing is important in software development because it allows for faster and more efficient testing of applications. It allows for multiple test cases to be run simultaneously, resulting in increased <a href="https://testsigma.com/blog/code-coverage-vs-test-coverage/" target="_blank" rel="noreferrer noopener">test coverage</a>, improved accuracy, scalability, cost savings, and improved <a href="https://testsigma.com/blog/roi-test-automation/" target="_blank" rel="noreferrer noopener">ROI</a>. To conduct parallel testing, divide your test suite into smaller subsets that can be executed simultaneously. The most critical details in this text are the steps to set up a test environment with sufficient resources to:



<ol><li>run multiple tests in parallel</li><li>configure a <a href="https://testsigma.com/blog/understanding-agile-testing-framework/" target="_blank" rel="noreferrer noopener">testing framework</a> to support parallel execution</li><li>run the parallel tests</li><li>monitor and analyze the results</li><li>debug failed tests</li><li>re-run the failed tests</li><li>identify and fix any issues</li></ol>



And repeat the process until all tests have been executed successfully. This can be done manually or using a testing framework that supports parallel execution.



<h2 id="h-creating-parallel-testing-in-testsigma">Creating Parallel Testing in Testsigma</h2>



In Testsigma, you can write automated tests in plain English with zero coding expertise and run them across multiple device/browser combinations you prefer.



Let’s see how Parallel Testing is performed in Testsigma.To execute automated tests in parallel, we need more than one Test Case(a specification of what is to be tested and what outcome is expected) and a Test Suite(a group of test cases).

</faq>

How do you Conduct a Parallel Test Execution?

If you are a programmer or if you know the basics, you might already be familiar with Conditional &#8216;If&#8217;, &#8216;Else&#8217;&nbsp;and &#8216;Else&#8211;if&#8217;&nbsp;statements. Even If you haven&#8217;t heard about these yet, this article would be helpful.



The conditional statements in general, help take actions depending on whether a programmer-specified condition or criteria evaluates to true or false.&nbsp;



In Testing context, these Conditional statements provide control over Test execution, i.e the flow of test execution depending upon the conditional steps. To understand this, let&#8217;s write a sample test case.



<div id="toc_container" class="no_bullets">Table Of Contents<ul class="toc_list"><li><a href="#Example_1_If_and_Else">1 Example 1: If and Else</a></li><li><a href="#Example_2_If_Else-If_and_Else">2 Example 2: If, Else-If, and Else</a></li></ul></div>
<h2 id="example-1-if-and-else">Example 1: If and Else</h2>



Step 1 :&nbsp;We start with a simple&nbsp;Go to step.



<figure class="wp-block-image"><img src="https://testsigma.com/blog/wp-content/uploads/2019/05/up.jpg" alt="Step-1"/></figure>



 



Step 2 : Click on Add Next Step. When the new Test Step box appears, tick the checkbox “Add Conditional If”.



Now, select the expected outcome after the execution of Test Step from the drop-down menu(Passed, Failed, Aborted, Not Executed, Prerequisite Failed, Queued or Stopped).



<figure class="wp-block-gallery has-nested-images columns-default is-cropped">
<figure class="wp-block-image size-large"><img loading="lazy" width="1061" height="522" data-id="3252" src="https://testsigma.com/blog/wp-content/uploads/2019/05/two-r.jpg" alt="two-r" class="wp-image-3252"/></figure>
</figure>



 



Here we select “Passed”. Let&#8217;s move on to add a Test Step. I&#8217;m using the grammar, &#8220;Verify that the element swdLink displays text Software development&#8220;. Now click Create.



Here, &#8220;swdLink&#8221; indicates the <a rel="noreferrer noopener" aria-label="Here we select “Passed”. Let's move on to add a Test Step. I'm using the grammar, &quot;Verify that the element swdLink displays text Software development&quot;. Now click Create. Here, &quot;swdLink&quot; indicates the ui identifier and &quot;Software development&quot; is the test data. (opens in a new tab)" href="https://support.testsigma.com/support/solutions/articles/32000025969-what-is-ui-identifier-" target="_blank">ui identifier</a>.



&#8220;Software development&#8221; is the test data(are input values that we give; say, in an input form like date, name like john, etc).

What is test data? Test Data are input values(valid and invalid username/password combinations or phone number, etc). Here, test data is read from Excel, JSON, properties file or even from plain text files.



Selenium can be used for <a href="https://en.wikipedia.org/wiki/Data-driven_testing" target="_blank" rel="noreferrer noopener">Data-Driven Testing</a> but it needs additional APIs to read the test data from text files, and a loop statement in the code which in turn increases the complexity. 



But Data-Driven testing in Testsigma is as simple as it can get. You just upload the test data file and start using anywhere on your tests. Let&#8217;s see how. 



<div id="toc_container" class="no_bullets">Table Of Contents<ul class="toc_list"><li><a href="#Running_a_Data-Driven_test_in_Testsigma">1 Running a Data-Driven test in Testsigma</a><ul><li><a href="#Method_1nbspCreating_a_Test_Data_profile_manually">1.1 Method 1:&nbsp;Creating a Test Data profile manually</a></li><li><a href="#Method_2_Importing_a_Test_Data_profile">1.2 Method 2: Importing a Test Data profile</a></li></ul></li><li><a href="#Test_Data_management">2 Test Data management</a></li></ul></div>
<h2 id="running-a-data-driven-test-in-testsigma">Running a Data-Driven test in Testsigma</h2>



Pre-requisites: We need a valid test data profile which is mandatory for Data-Driven testing. 



There are two simple methods to do this:



1. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;By Creating a test data profile manually



2. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;By Importing a test data profile 







<h3 id="method-1-creating-a-test-data-profile-manually">Method 1:&nbsp;Creating a Test Data profile manually</h3>







Here is how Testsigma’s dashboard looks like.



<figure class="wp-block-gallery aligncenter has-nested-images columns-default is-cropped">

</figure>



 



Click on &#8216;Test Development&#8217; and click on the Create icon at the top right corner. Enter the test data inputs, provide a name for the test data profile and click Create.



 



<figure class="wp-block-image size-large"><img loading="lazy" width="1916" height="940" src="https://testsigma.com/blog/wp-content/uploads/Data-Driven-Testing-Method-1-2-gif.gif" alt="Data driven testing method-1" class="wp-image-15357"/><figcaption>Creating Test Data Profile Manually</figcaption></figure>



<h3 id="method-2-importing-a-test-data-profile">Method 2: Importing a Test Data profile</h3>



To import the test data profile that you created, click on the Import icon in the test data page, provide a name for the test data profile and upload your file.



There is a sample test data file in the link provided with the format to be used. Now, click Create.



 



<figure class="wp-block-image size-large"><img loading="lazy" width="1916" height="940" src="https://testsigma.com/blog/wp-content/uploads/Data-Driven-Testing-Method-2.gif" alt="Data driven testing method-2" class="wp-image-15349"/><figcaption>Importing Test Data Profile</figcaption></figure>



If we have the test data profile ready by either one of these 2 methods, we can create a Data-Driven test case in Testsigma.



 Click on the plus icon at the left panel.



Now click on the +Test Case(Create a new Test Case) button, enter the name of your Test Case and click on “Take me to a detailed form” link which shows a few more options.



Now, select the profile that you created, Click the data-driven toggle button and hit Create.



 



<figure class="wp-block-video"><video controls src="https://testsigma.com/blog/wp-content/uploads/2019/04/Data-Driven-Test-Case_Testsigma.mp4"></video></figure>



 



Now that we have imported, let’s see how we can add this to our test steps: 



<ul class="list_style_disc"><li>In your Testsigma account, type in the URL of the page(Orange HRM login page which is open source</li>&nbsp;<li>Let’s enter something in the Username field of the page using the grammar, “Enter test data in the ui identifier field”.

You may check out all the grammar used in Testsigma in the NLP Grammar link at the left pane of your Testsigma account or use the Help icon to see the keywords you can use and the examples that would help you with a few examples.



<ul class="list_style_disc"><li>Now let’s see how we can use the testdata without hardcoding it to the test step.</li></ul>



Delete the text testdata and select the @|Parameter| from the suggestions. Instead, choose the testdata name that comes up on the suggestions. See representation.



 



<figure class="wp-block-video"><video controls src="https://testsigma.com/blog/wp-content/uploads/2019/04/Choose-Test-Data-Profile_Testsigma.mp4"></video></figure>



 



<ul class="list_style_disc"><li>Now, you just need to create a simple Dry Run and click Create and Run.</li></ul>



This is just an example for illustrating data-driven testing. There are a whole lot of possible ways you can put to use the test data without necessarily hard coding it to your test steps.

Overcome common Regression Testing challenges and ensure that any change does not impact the quality of the software deliverable. Agile development is acclaimed for delivering working software frequently. Each time it adds or enhances a minor feature that is of value to the customer.



We need to plan our <a href="https://testsigma.com/regression-testing" target="_blank" rel="noreferrer noopener">Regression Testing</a> effectively to cater to the changing demands in Agile. Let us start with one of the major Regression Testing challenges.<gwmw style="display:none;">

<h2 id="top-8-regression-testing-challenges">Top 8 Regression Testing Challenges</h2>



Regression testing ensures that modifications or upgrades to a program or system do not affect previously tested functionality. However, various issues can influence the quality of the testing process, such as the following.<gwmw style="display:none;">



<h3 id="1-optimizing-and-selecting-the-right-test-cases">1.Optimizing and selecting the right test cases</h3>



The test cases affected due to a change may not be the same reason for another. Identifying the relevant affected test cases is a major problem in Regression Testing.



Prioritize test cases affected by a new function addition, update, or edit. Only run these instead of a complete test suite with irrelevant test cases and overloading. Identify the affected regions and analyze how changes, new features, or bug fixes might have impacted existing features and functionalities.



Regularly monitor and perform periodic cleanup to remove obsolete and duplicate test cases from the regression test suites.



If the Automated regression testing is done consistently, it will be easier to optimize and maintain the right test cases.

</div> 



<h3 id="2-test-authoring-time">2.Test Authoring time</h3>



It could be challenging to keep up with the pace of delivery in Agile with the huge scripting necessary time to test a simple functionality and rewrite every affected test. Updating and maintaining huge scripts at any time requires understanding the existing code. But one major disadvantage of Selenium is the huge test authoring time required.<gwmw style="display:none;">



Cutting down on the test authoring time allows us to use the full benefits of automating the regression testing process. This is now possible with the advent of Scriptless Automation Testing tools! Now, the tests can be <a href="https://testsigma.com/test-development" target="_blank" rel="noreferrer noopener">written using natural language</a>; This makes it easy for anyone to refer to the tests and make changes easily at any time.

<h3 id="3-close-the-communication-gap">3.Close the Communication gap</h3>



Effective communication forms the basis of the success of Agile. Continuous engagement with the team ensures that the client expectations are met, testers find quick solutions to issues and the deliverables meet customer expectations. Quite often, major issues or bugs are not identified early because the process was not followed and the team failed to communicate with each other.



A useful communication tool that will help understand the status of the project and broadcast changes.



<h3 id="4-examine-and-choose-the-right-automation-testing-tools">4.Examine and choose the right automation testing tools</h3>



We need to choose Automated Regression Testing tools that make the re-editing or rework of Regression Testing easier. You may want to refer this guide to help you <a href="https://testsigma.com/blog/how-select-right-automated-regression-testing-tool/" target="_blank" rel="noreferrer noopener" aria-label="We need to choose Automated Regression Testing tools that make the re-editing or rework of Regression Testing easier. You may want to refer this guide to help you choose an Automated Regression Testing Tool effectively. (opens in a new tab)">choose an Automated Regression Testing Tool</a> effectively.



Intelligent automated regression testing tools like Testsigma help you create Regression test plans automatically and suggest all affected automated tests and areas so you can spend less time identifying affected areas and advice fixes.



The main challenges with conventional test automation are building a robust and maintainable automation framework and managing the “likely to change” objects and ui-identifiers. The automation testing tool must ensure that the automated tests are reusable and maintainable and non-resistant to changes in the application UI and also ensure that the automated tests remain stable(automatically).



What you can do is get the vendors to demonstrate how implementing their tool will minimize risk and improve the release quality.



Ensuring that a website functions as expected in all major browsers and mobile devices or tablets across different screen resolutions and sizes is challenging for testers in agile projects to manage and run them in parallel. It is particularly daunting to perform Regression Testing across browsers and devices. Managing environment specific datasets and variables that are likely to change in multiple execution environments at each stage like Development, Testing, Staging, Production is also crucial. Check if the automated regression testing tool offer real devices for testing to speed up your run times.



Also, choose an automated regression testing tool that can integrate with tools such as Jenkins, so you can run your regression tests continuously right from the first build incrementally and collate the results on a consistent loop integrated with the testing server which helps in getting actionable feedback allowing dev teams to act on them immediately in contrast to late hitting bugs towards the end of the sprint.

</div> 



<h3 id="5-reduce-the-dev-test-complete-gap">5.Reduce the Dev/Test Complete Gap</h3>



Regression tests must be run after every development iteration and after changes are made. The delivery pipeline should trigger regression tests automatically whenever a successful build is made. This results in a shorter feedback loop between developers and testers, leading to faster error identification and fixing. This saves time compared to testing postponed towards the end of the cycle.



<h3 id="6-build-automation-in-sprint">6.Build Automation In-sprint</h3>



Automation usually lags by at least one sprint. Teams take the risk of ignoring regression testing of the new feature at the end of the cycle due to the amount of manual effort and time required to achieve complete test coverage. Instead, the tester can begin building the skeleton of an automated test and fill in the objects/element ui identifiers later when the application UI is available.



Once the UI is close to done, all the participants should be working more closely to complete the UI mapping. This ensures the tests are completely automated along with the development and ready to run through continuous integration.



By the time the code is complete and ready to be committed, there are unit tests, API tests, and a handful of automated UI tests. The feature is all set for automated regression testing and then to move to the production.



Regression testing is now faster and the development flow will be smooth.



<h3 id="7-deal-with-changing-requirements">7.Deal with changing Requirements</h3>



The Agile methodology allows for change in requirements even late in the development. The scrum teams need to be prepared to accept the late change in requirements. When the requirements change, especially towards the end of the sprint and a particular functionality hasn’t been tested well, the team should make informed decisions whether to release the feature or push it to the next sprint based on the criticality of that function/feature. If this is the case, you could do a heads off by performing basic Sanity testing of the changes and not go into deeper levels of testing.



It can also be the case that the user stories/requirements are not recorded appropriately and, the team missed out on critical functionalities. This can also happen as a result of not involving testers in the early planning/designing phases or due to improper documentation.



Many a time, product requirement documents are too often read once and left which isn’t ideal for an Agile process. This creates a challenge for testers because there is a lack of understanding and requirements, so proper test cases can’t be constructed.



<h3 id="8-perform-some-exploratory-testing">8.Perform some Exploratory Testing</h3>



When everything goes fine, you could do some free unrestricted or “not bound by rules” testing with less or no documentation. You can see if you missed out on anything or an unused feature.



It would be wise to set a dedicated time for some exploratory testing complementary to Regression Testing to explore other areas of the software like a real user would.



The purpose of regression testing is to unmask abnormalities, unexpected behavior as a result of change, updates, or re-releases. For this, it is required that every relevant test case that has direct or indirect impact is run within the limited span of time in the sprint.



It is mandatory that a consistent test management and requirement management approach is followed right from the early stages within the automated regression testing tool you choose.

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



<h3 id="what-are-the-disadvantages-of-regression-testing">What are the disadvantages of regression testing?</h3>



One of the major disadvantages is the time and effort necessary to run regression tests, which may be particularly significant in big, sophisticated applications. Additionally, regression testing may not always capture all faults, and it may be impossible to test every scenario fully in some cases.



<h3 id="how-do-you-overcome-regression-testing-challenges">How do you overcome regression testing challenges?</h3>



A well-defined testing strategy and relevant tools and methodologies are necessary to address the obstacles of regression testing. This includes prioritizing test cases based on criticality, maintaining appropriate test data management standards, and employing automated testing technologies to boost productivity and decrease the risk of human mistakes. Testing should be carried out throughout the development lifecycle.



<h3 id="what-are-the-pros-and-cons-of-regression-testing">What are the pros and cons of regression testing?</h3>



Regression testing helps verify that previously tested functionality is not impacted by modifications or upgrades. It can detect errors early in the development process and evaluate the program&#8217;s overall quality. The time and effort necessary to run regression tests, the expenses involved with maintaining and upgrading test cases and data, and the chance that it may not identify all flaws are all disadvantages are also a few of the regression testing challenges. The choice to do regression testing should be based on a detailed examination of each project&#8217;s possible advantages and drawbacks.
