5 Best Platforms That Support Regression Testing in 2025

Every software update, whether a new feature, a bug fix, or a security patch, comes with the risk of breaking existing functionality. Regression testing prevents this by re-running tests to ensure that recent changes haven’t caused unintended issues.

However, manually testing everything after each update isn’t realistic, especially with frequent releases. Automated regression testing solves this by running test cases quickly and accurately, reducing human effort and minimizing errors. According to GitLab’s 2024 DevOps Report, 60% of developers deploy multiple times a day, making automation essential for maintaining software quality.

With CI/CD pipelines and Agile development driving faster release cycles, the demand for efficient regression testing tools is growing. This guide covers five of the best platforms in 2025.

What is Regression Testing?

Every time a software application is updated whether it’s a new feature, a bug fix, or a performance improvement there’s a chance that something that was working perfectly before might stop working. Regression testing is the process of verifying that these updates don’t introduce new issues or break existing functionality.

Regression testing isn’t just a one-time task, it’s needed whenever there’s a change in the code. Some key situations include:

• To confirm that the existing features still work as expected.
• To ensure that a bug fix doesn’t introduce new problems elsewhere.
• To verify that speed improvements don’t cause functional errors.
• To check that external dependencies don’t disrupt functionality.
