Regression testing is essential to ensure that code changes do not negatively impact existing software functionality, especially when adding new features or fixing bugs. While regression testing helps maintain software quality and mitigate risks, it can be time-consuming and repetitive without automation tools, and may pose challenges in agile development environments. Key benefits include improved test coverage and identifying vulnerabilities before they affect performance.

1. All You Need To Know About Regression Testing
Regression Testing Becomes Very Important When:
Why Is Regression Testing
Needed For App Frameworks
Regression testing is a testing cycle that
confirms that the changes made in the
codebase do not hurt the existing
software framework and functionality.
Regression tests are important in the
multiple test framework before certain
software deployment.
You have added new
features to the software
framework
You have fixed some bugs
recently that introduce
some minor changes
You have updated an
existing feature for
better functionality
As a developer, you have to ensure that the software framework is not affected in a broad sense due
to the above changes. The developer completes regression testing cycles by employing the same
testing cases against the newly updated framework he had employed against the previous code
framework and cleared. If the new code framework clears through these test cases just like the
previous versions of the code, the regression test is successful.
Pros of Regression Testing
Checks for any changes in the code affecting the overall functionality so that the functionality
can be maintained after modification
Ensures that the issues and bugs fixed in improvement cycles do not recur in the framework.
Mitigates risks arising during multiple testing cycles, so code errors have no domino effect.
Easy to do, learn about and analyze results for complete insights on necessary actions.
Cons of Regression Testing
The Best Regression Testing Tools
The type of testing can be very time-consuming for the developer if he does not employ
any automated tools.
The developer has to perform these tests for any small code change. This can be very repetitive
for developers without tools and assistance.
The regressive testing phases are not suitable for agile model development as they can make
the testing approach rigid.
The developer has to create complex tests for every testing cycle of regression.
The developer needs automated, supportive tools for every regression test cycle
Benefits of Regression testing
Regression testing needs certain practices by an extensive developer team for proper results.
Regression testing maintains the concurrency of the code between old and new versions.
Regression testing covers more area of software in one go, helping improve test case coverage
for the entire software
Regression testing allows the developer to know the vulnerabilities before they become highly
problematic to the app's performance.
Regression testing helps create high quality software after every cycle of testing.
