How do you form a list of tests for regression testing in a project?

To form a regression test suite, tests that cover critical and frequently used functional areas are usually selected, as well as those that verify recently fixed bugs and modified functionalities. It is important to include:

• Tests that verify core business processes.
• Tests related to recent code changes.
• Tests that identified bugs in the past (to avoid repeating errors).

Automated tests are often used to speed up the process. It is also useful to maintain an up-to-date set of tests by removing outdated ones and adding new ones as the project develops.
