Why is Regression Testing In Agile?

Regression testing is crucial to Agile development because it guarantees that previously developed and tested applications or software continue functioning successfully following modifications, such as enhancements, bug repairs, or new features. Agile development involves iterative cycles, or sprints, and frequent codebase modifications that may inadvertently create new issues or break previously functional features. Regression testing reduces this risk by repeating previously completed test cases to verify that the software continues to behave consistently even after changes have been made.

What’s the role of regression testing in Agile?

Regression testing safeguards current software features against unfavorable outcomes from newly added or modified code in agile development.

Regression testing involves testers confirming that all expected and required functionality is being passed by the updated code base (the code base following modifications that have been merged). The primary objective is to preserve current functionality while avoiding the introduction of new bugs. Agile regression testing is important because it supports software quality and stability during iterative development cycles, adheres to the principles of Agile methodology, and makes software development processes more reliable and efficient.

Conclusion:-

Agile relies heavily on regression testing to make sure that new code changes don’t interfere with already-existing functionality. Regression tests contribute to the system’s reliability throughout several releases because of the iterative, agile nature of frequent upgrades. Regression test automation allows teams to confirm that the program is still dependable rapidly. The continuous input from these tests helps Agile achieve its objective of producing high-quality software quickly. Regression testing ultimately lowers the chance of errors while preserving the development process’s flexibility.
