Regression testing has three most prominent implementation methods, including re-test all, regression test selection, and test case prioritization. In this technique, regression testing is applied to all existing test suites. Although it is the safest way to ensure all bugs are detected and resolved, this method requires substantial time and resources. That is why the complete regression approach fits better in certain contexts — for example, when the application is adjusted for a new platform or language, or when the operating system gets a major update.
Minimize effort to create a test suite with Parallel Testing. You may select the relevant parts that can be affected by the changes and perform regression testing on these chosen parts only. By picking out the related areas, you can apply limited and relevant test cases to reduce both the time and effort invested in regression testing. You may choose to prioritize test cases that must be included and performed first in the regression testing process. These test cases should be prioritized based on these criteria: failure rate, business impact, and gradually used functionalities.
The test cases that relate to customer-facing aspects and newly added functionalities are of high priority as well. The two terms re-testing and regression testing can be confusing for automation novices.
They might sound similar but are entirely different from each other. Re-testing takes place when a defect in the source code is fixed or when a particular test case fails in the final execution and needs to be re-run. Regression testing is performed to find out whether the updates or changes had caused new defects in the existing functions. This step would ensure the unification of the software.
In a typical software development pipeline, re-testing is performed before regression testing practices. Re-testing solely focuses on the failed test cases; while regression testing is applied to those that have passed, in order to check for unexpected new bugs.
Another important note is that re-testing includes error verifications, in contrast to regression testing. Moreover, automation is a crucial feature in regression testing, allowing you to make the most of your test case capabilities. Additionally, regression testing eliminates all underlying side effects caused by code changes in the most cost-effective way possible.
With the Agile development approach , teams can gain numerous benefits and values, such as accelerated time-to-market, ROI, customer support, and product improvements. However, this comes with a significant challenge of balancing between sprint development and iterative testing to avoid conflicts as the product matures. Agile implementation of regression testing plays a key role in aligning the existing and updated functionalities, avoiding all possible rework in the future.
Agile regression testing ensures the business functions are stable and sustainable. On another note, regression testing helps developers to focus their efforts on building new functionalities for the application rather than keep on returning to check for defects in the old features. Applying regression testing reveals the unexpected risks in software builds, helping developers to respond more quickly and efficiently.
Regression testing is key to improve the overall quality of the product and user experience. The right regression testing tools can significantly identify all surfaced defects and eliminate them early in the pipeline. In addition, regression testing in Agile offers a host of technical and business advantages. Selenium can be used for browser-based regression testing. It uses VBScript language for automation. It is a Data-driven, Keyword based tool.
This is primarily used for automating regression test cases and it also integrates with Rational Test Manager. Configuration Management during Regression Testing becomes imperative in Agile Environments where a code is being continuously modified.
To ensure effective regression tests, observe the following :. Retesting means testing the functionality or bug again to ensure the code is fixed. If it is not fixed, Defect needs to be re-opened. If fixed, Defect is closed. Regression testing means testing your software application when it undergoes a code change to ensure that the new code has not affected other parts of the software.

We should have "just the right amount" of depth in each trade, but our true value is seeing how each trade works with the others to advocate for users. QA must depend on the expertise of each component owner in the software cycle, and must foster relationships with them. That's why QA can't be the only ones responsible for regression testing. QA should not be simply an inspector of dev code, but rather should explore the overall customer experience from a broader, more user-based vantage point.

Time to step up, devs. Here's why regression testing responsibility needs to be shared between QA and devs. They do this because the headlines are littered with big and small companies who have suffered major setbacks due to software glitches. Many, if not all, of these issues, could have been avoided with better testing. Comprehensive regression testing of an application with every release, before it goes live, is essential to avoid becoming the next headline.
While that part is pretty cut and dry, the bigger question is who is responsible for doing it. While it has traditionally been done by a dedicated tester, depending on your organization, it could be performed by a developer or even an automated test tool. There are even automated test tools that use artificial intelligence to perform regression testing. Typically, however, regression testing is performed by a test engineer who creates and manages the test cases, ensuring that all modules are effectively tested and working according to user specifications.
The key thing to remember is that regression testing is a key part of the release process — every bit as important as the development itself.
The stages of testing shown in the above diagram are identical regardless of whether your organization uses Agile or DevOps. The key difference between them arguably comes down to minor changes in the development lifecycle, and who is responsible for the various stages of testing. With the Waterfall methodology the various testing stages were clear cut and well defined by different individual and team roles. Developers developed, testers tested and managers managed.
However, with the continuous delivery and continuous testing model of Agile, those well-defined lines have become blurred. As companies try to improve development life-cycle efficiency, the responsibilities associated with each stage have shifted left. In practice, this mean that developers were now taking on a significant amount of the testing to expedite issue resolution and code release. Then organizations began implementing DevOps with the goal of improving efficiency even more, which blurred the lines of finite roles even further and the responsibilities shifted even further to the left in the cycle.
This meant that developers would take on more testing, and testers would take on more development. In some cases, even tasks that would traditionally have been the responsibility of operations would now be performed by testers and developers — interacting directly with the customer, identifying issues, and then quickly resolving them.
The only way to develop quality software as quickly and efficiently as possible is to provide efficient, effective regression testing. Application testing in a large enterprise needs to be performed in a wide variety of environments that mimic the production environment as closely as possible. There are many ways to do this. One of the more popular methods is called Service Virtualization. In simple terms, this creates a virtual environment that simulates the production environment.
This allows developers and testers to test their new code in an environment as close to live production as possible.
