How regularly did you create and maintain automated tests in your projects?

I regularly created and maintained automated tests, usually within each sprint or development iteration. After adding new functionality or fixing bugs, I immediately wrote corresponding tests to cover the changes. I also periodically reviewed and updated existing tests to keep them relevant and reflective of the current application logic.

In Python projects, I often used frameworks like unittest or pytest, which allowed for quick creation and execution of tests. Regular maintenance of the test base helps quickly identify regressions and improves product quality.
