Is it necessary to perform regression testing daily during the development process?

Regression testing is aimed at verifying that new changes in the code have not disrupted existing functionality. It is desirable to perform regression testing daily, especially during the active development phase when the code changes frequently.

Advantages of daily regression testing:

• Quick detection of errors caused by new changes.
• Maintaining product stability.
• The ability to promptly fix defects.

In modern development processes (for example, using CI/CD), regression tests are often run automatically with each commit or build. This helps maintain quality without significant time costs.

However, if the project is small or changes are infrequent, regression testing can be performed less often, for example, before a release.
