5 Best Practices of Regression Testing

The tester must identify all points where changes were made and then update the test cases accordingly.

Introduction: What is Regression Testing?

Software regression testing is the process of verification that new or changed software behavior matches the expected behavior. When bugs are fixed, software changes are made, or new features are added, regression testing is one way to verify that what was done was successful. Regression testing is an integral part of any software development process.

Regression Testing can be automated or manual. Automated regression tests are specifically written to test changes made to the system and its interactions with other systems. Manual regressions tests are conducted by an individual tester who runs through a set of carefully crafted scripts to test for expected functionality on a changelog provided by the developer. The tester must identify all points where changes were made and then update the test cases accordingly.

What are the five best practices of regression testing?

Regression testing is the process of checking to make sure that a change or new element does not break or cause unintended problems to exist features. This article will list the five best practices of regression testing.

1. Use an automated regression testing tool: Automating your tests is crucial for saving time and ensuring quality. A good automation tool enables you to test your website against many different browsers, operating systems, and devices in one go, which saves you loads of time in the long run.

2. Performing Exploratory Tests before automating test scripts: The point of exploratory testing is to understand better the product, the tools you are using, and the process.

Performing an exploratory test before running your automation scripts will help you find potential issues with your scripts before they cause problems for your business.

3. Maintain and Revise Regression Pack regularly

The regression pack is primarily a compilation of test cases executed when new software is upgraded. The scripted tests included in a pack are designed with the prerequisites of older software versions in mind. Ad-hoc or random tests can be simply integrated into the pack by testers. Regression tests can be laborious and time-consuming; the last thing you need is to count tests to see if an old feature that has been removed is still functional.

4. Only run a full regression suite when necessary.

It is not necessarily necessary to run the entire regression suite on every single build. In the case of a minor release, it is prudent to run or execute only the smoke tests and regression testing for any modules that have changed. To keep things easy, organize the test cases in regression testing according to the module of the AUT covered by each test. 

5. Determine which of the most essential regression test cases should be prioritized.

Because running all of the test cases in your regression pack can take a long time, it’s preferable to focus on the most critical or frequently used functions first. When time or financial restrictions prevent you from executing every test case in your regression pack, testing the most critical functions is an effective way to mitigate risks. 

Conclusion: Regression testing allows businesses to avoid the risks that come with updating applications, websites, or any other digital product. Bugs that limit specific functions to those that produce severe security vulnerabilities are all examples of these dangers. Software problems created by software upgrades, on the other hand, might enrage your customers, resulting in a drop in your brand’s image and income.
