Within the dynamic realm of software development–an arena where change is not only constant but also inevitable: ensuring that new updates do not disrupt existing functionalities becomes paramount. Enter Regression Testing; it plays a crucial role in this context. This article, aiming to demystify regression test and illuminate its purpose, and process—along with identifying optimal times within the software development lifecycle for performance—is our contribution towards greater clarity on these critical aspects.

What is Regression Testing?
A quality assurance process, Regression Testing re-runs previously executed test cases; its primary goal: is to ensure that the introduction of new code changes does not affect existing functionalities. This strategy actively detects and addresses unintended side effects or defects potentially arising from software modifications.

When Should You Perform Regression Testing?

After Code Changes:
Introducing code changes – be it bug fixes, new feature additions or enhancements: Regression Testing emerges as an absolute necessity; this process guarantees that the modifications don’t detrimentally affect validated aspects of the software already in existence.

Periodic Releases:
Before each software release or deployment, perform Regression Testing: this action ensures the application’s stability and reliability–even as it undergoes evolution with novel features or enhancements.

Integration of Third-Party Components:
Integrating third-party components or libraries into the software necessitates essential Regression Testing: changes in the environment or dependencies may inadvertently impact the system. Running regression tests–a critical tool for identifying and rectifying any issues–is therefore imperative.

Environment Changes:
Necessary for ensuring the software’s compatibility and stability under different conditions, Regression Testing becomes imperative when changes occur in the testing environment – particularly updates to the operating system, database or server configurations.

Defect Fixes:
Performing Regression Testing proves crucial after addressing defects or issues identified in earlier testing phases; this process ensures that the fixes neither introduce new problems nor compromise other functionalities within the system.

Routine Maintenance:
Throughout routine maintenance activities such as software updates or patches, Regression Testing ensures the application’s overall integrity is upheld.

The Process of Regression Testing:

Test Selection:

From the existing test suite, identify a subset of test cases that must cover critical functionalities and interactions within the application.

Test Execution:

To ensure that the modifications do not introduce new defects or negatively affect existing features, execute the selected test cases on the altered code.

Comparison of Results:

Thoroughly investigate any discrepancies or deviations by comparing the results of the current test run with previously established expected outcomes during prior testing phases.

Defect Resolution:

Identifying and promptly documenting new defects remains crucial; the overarching aim is to preserve an impeccable, stable software application: one that operates without errors.

Automation:

To streamline repetitive tasks, consider automating the Regression Testing process: this can be achieved through the utilization of Automated Regression Testing tools. These sophisticated instruments execute a comprehensive set of test cases with speed and efficiency; hence–enhancing overall productivity.

Conclusion:

Software development can be complicated. Regression testing is important to make sure changes don’t break existing features. Opkey is a test automation company that uses artificial intelligence to automate testing. This helps companies test their software better.

It not only saves time and money running tests but also makes testing much faster. Instead of just cutting costs, Opkey also aims to completely change how companies do regression testing.
