What types of testing have you used in your projects?

In projects, I used several types of testing to ensure the quality of the software product:

• Unit Testing: testing individual functions or methods for correctness. Usually automated using frameworks (e.g., NUnit, JUnit).

• Integration Testing: testing the interaction between multiple components or modules to ensure they work together correctly.

• End-to-End (E2E) Testing: simulating real user behavior, testing the entire system, including UI, API, and database.

• Automation Testing: writing scripts for automatic test execution, which speeds up the process and reduces human error.

Using different types of testing helps identify errors at various levels and increases product reliability.
