What types of tests are used in continuous integration (CI) process?

The following types of tests are typically used in continuous integration (CI):

• Unit tests — verify the correctness of individual functions or methods.
• Integration tests — check the interaction between modules or components.
• Functional tests — ensure that the system performs the declared functions.
• Smoke tests — quick checks to confirm that the main functions work and the build is not broken.

The main goal is to quickly identify errors early in development to prevent them from reaching the release.
