Regression testing is a software testing technique that focuses on ensuring that new code changes or modifications to an existing software application do not adversely affect the existing functionality. The primary goal of regression testing is to identify and catch any unintended side effects or defects that might have been introduced when new features are added, bugs are fixed, or code is updated.
It is a critical quality assurance practice that ensures that an application continues to function correctly and reliably as it undergoes changes and updates. It helps catch defects early in the development process, reducing the risk of releasing software with unintended issues.
Addressing these challenges in regression testing often involves careful test case management, test automation best practices, version control for test scripts and data, continuous monitoring of test environments, and collaboration between development and QA teams. It’s important to strike a balance between thorough regression testing and efficient testing practices to ensure software quality while maintaining development velocity.
