Automated Regression Testing Strategy For Agile Environments

April 14, 2021

In addition, if it also makes test case creation simpler and easier, then it further reduces your investment cost and enables returns faster. Imagine a scenario where your customers see a nasty bug in your application the day a major release was rolled out.

The testing team gets down to work and runs all test suites/scripts they developed to cover the product. When testing is done, the team hands bug reports to the development team, who then fixes the bugs. The choice of an approach depends on the scope of changes, the methodology and the stage of product delivery process. In our testing practice, we stick to risk-based partial regression testing whenever possible. In this case, regression testing assures that the software product performs flawlessly after integration with another product. Targeted feedback – You can use automated tools to work with parts of the system that might be trickier to get to when testing normally.

That’s why the ‘retest everything’ practice is rarely used among testers and, in the case where a team decides to go with it, the sessions will most likely be automated. The tip is to identify the points of integration and analyze how the changes, new features or bug fixes might have impacted the older features and functionality. Create new test cases for testing and verifying the correctness of integrated application. These test cases can be added to your regression suite now. Selection of test cases for the regression test suite is yet another challenge of regression testing. You want to make sure that all points of integration and changes are being verified by the regression. At the same time, you can not overload your regression test suite with test cases as you get less time for regression testing.

At this stage, a tester re-executes a set of cases they ran during the initial development stage to ensure there is no negative impact. It’s important to test not just the part of the code that has been modified or a newly added feature but the entire system. Closely monitoring of changes hold a vital importance in regression testing.

Azure Test Plans: Test Plans

These tools range from full-featured vendor products to open source options. Regression testing helps teams manage the risks of change. What happens once you finish the final build’s regression testing phase? Your manager will want a detailed report of the test cases executed, bugs found or removed, etc. A test closure report will have a summarized report of all the pretest and post-test details that the management will need before release. It’s time to discuss the things to check while carrying out regression testing. We shall divide the regression test plan checklist into three sections.

Consequently, it requires many resources and is usually expensive. At the same time, it provides the most detailed picture of the current state of an application. Performing continuous testing is how you’ll get the most out of your regression tests, and it should be a process incorporated into overall DevOps. Get the ultimate overview of the role of regression testing in software testing in this blog. A comprehensive regression testing plan regression testing is not so much about the number of test cases, as it is about covering the critical conditions. These conditions assure that the functionality remains, that the bug-fixing has been successfully done, and a particular functional area is capable of handling unexpected behavior. Purely undertaking regression testing by the number of cases is not very easy, nor is it practical.

How To Perform Regression Testing?

While for a landing page regression testing mostly features UI and usability test cases, for a portal it may employ multiple test cases for security, performance, compatibility testing and more. In some cases, developers revise the existing functionality and discard or edit some features. In such situations, regression testing checks whether the feature in question was removed/edited with no damage to the rest of the functionality. This is the most hire an app developer common reason to run regression testing. When developers introduce new code, they don’t fully concentrate on its compatibility with the existing code. Too much trust in automated reports – Automated tools can only tell you what has changed from the expectation you put into the tool and what currently exists in the system. Use other testing techniques around a suspect area of the software to determine if there is a regression in quality or not.

Regression testing in Agile is best done with test automation and continuous testing tools. This keeps teams focused on regression testing plan innovation through new features and releases. This reduces risk as well as the time it takes developers to fix them.

Random Testing Of User Scenarios

Integration regression test cases are executed to verify the interaction between units of the application with each other and with back-end services such as regression testing plan databases. It is not uncommon for this step to be called “regression testing,” although regression test cases are executed at every stage of development.

Up-front planning between you and the rest of your team can give clarity and visibility to your regression testing approach. Ask questions about the product and project, and learn to work and search for ways to improve yourself and your team, then you will be successful. A team that collaborates and communicates well about regression risks can make regression testing smoother. It doesn’t need to be a drain on your resources, but rather another awesome tool in your testing toolkit.

When should you start regression testing?

Regression testing should be performed after any change is made to the code base. Additionally, regression tests should also be executed anytime a previously discovered issue has been marked as fixed and must be verified.

After carrying out a second or third testing cycle, you can compare the outcomes with the expected or previous ones. Regression testing is a type of repetitive testing of a pretested code. The goal is to detect the sudden defects that arise because of code changes. The important distinction is that a critical function may not always be high risk. For example, mail merge may be prone to problems, but would likely not prevent the application from being usable overall. Criticality is the degree of dependence upon a particular function, process or system. As with all of testing, you need to prioritize on the functions that carry the highest risk as defined by the likelihood of failure and associated impact of failure.

How & When To Do Regression Testing

CodeceptJS in a JavaScript end-to-end testing framework. It can work with WebDriver, Puppeteer, or any other driver. The tool has excellent test data management, test parallelization, and great reporting. The tool is super-easy to learn and has a convenient drag-and-drop UI that allows you to quickly create complex asynchronous tests. With that out of the way, let’s take a look at our toolset for automating regression testing. GUI testing where QA engineers validate different components by interacting with the user interface. It has a lower ROI and requires careful maintenance as GUI tests tend to break with changes to the app’s UI.

The standard Wikipedia definition of regression testing is the process of testing changes to computer programs to make sure that the older programming still works with the new changes. Regression testing is a normal part of the program development process and, in larger companies, is done by code software development teams structure testing specialists. Your ideal outsourcing partner should have a long and successful history of providing software quality assurance services. The company’s clients should include prominent and established firms. The company’s developers should all have proven track record and qualifications.

To conduct manual tests, consider visual regression testing, in which tools evaluate web applications from the end user’s perspective. This process can reveal when visual elements, such as images or text, overlap, as well as whether responsive design works as expected. Additionally, emulators and real devices provide a means of regression testing mobile apps from the user perspective.

Is Regression Testing Outsourcing Worth It?

This type of testing always precedes automation, in some cases being even more efficient than the latter. For example, it’s impossible to write test scripts for testing application areas adjacent to the part of the code that was changed. Large-, medium- and small-scale products require a different approach to regression testing.

Hence, it becomes a challenge for the testers to deliver the knowledge of existing features and functionalities to the new members. Similarly, new testers are not very comfortable in gaining knowledge of what happened in the past. It facilitates the writing of automated tests by mimicking the behavior of a user interacting with a website. It supports multiple browsers like Internet Explorer, Chrome, Firefox, Opera and Safari. If you’re struggling with time or budget and need to convince the rest of the business that automation is the right choice, we’re here to help.

Regression testing is also required in cases where the underlying technology is changed or upgraded due to old libraries are deprecated. To ensure that this does not have any impact on functionality, testers perform complete regression testing. Automating regression testing where your code is steady & uncomplicated will assure your product is running smooth while saving your developers and testers time. The above-mentioned approach, specific to reduce regression problems can go a long way towards a high brand value and good client relationship. Whenever the new software updates happen, it is important to keep updating your regression test suite and also keep adding new automated test scripts or updating the existing ones.

If we think about this in terms of testing, I individually unit tested the ingredients. After preparing the dish, I did integration testing as well.

If you’re doing the regression test 1,000 times, for example, you can hire automation testers to write the test scripts for regression and save your time & money. Now adays, most of the organizations are following Agile practices. Developers work on new functionality and release them in every apps & features 2-4 weeks as sprint release. In agile, it is sure that for every 2-4 weeks once there will be a code change. In this case, the regression tests help in testing the new code change in every iteration to make sure that tested application continues to perform correctly after every iteration.

Is regression testing part of UAT?

Is Regression Testing the Same as UAT? No! User Acceptance Testing, or UAT, is not the same as regression testing. In regression testing, retests are done on modifications to the software to make sure any new changes that have been introduced do not interrupt the activity of previously working software.

However, the most overlooked area may be the impact on your employees. During this session, Dr. Lawton-Thesing will dive into his doctoral dissertation examining the impact of ERP implementation on employee retention and satisfaction. You’ll hear real implementation stories and learn how you can avoid employee turnover and dissatisfaction during an ERP implementation at your organization. We use a large number of tools to run test cases – the list includes TestLink, JIRA, HP ALM, Microsoft TFS, and many more. In order to provide companies with agile maintenance, at Performance Lab we run continuous system monitoring of nightly and weekly builds. Build verification testing – a series of small tests aimed at verifying if a build is worth fixing or the damage is irreparable. Includes test cases that are not providing high project value but are crucial to avoid tech debt and complications for developers.

Select Your Test Cases For The Regression Suite

However, more automated test cases mean more maintenance. If you make your test cases too loosely coupled to product functionality, they may pass even when issues exist. However, if they are too rigid they will need to be rewritten and updated with every small change to the system. It is important to think of the techniques you will use to maintain and execute the tests. For example, how to apply test automation within your plan or selecting tests for manual testing and automated testing.
