What is the main function of testing frameworks in software development?

The main function of test frameworks is to automate the software testing process. They provide a structure and tools for writing, running, and organizing tests, which allows:

• Quickly verifying the correctness of code after changes.
• Ensuring repeatability and reliability of tests.
• Simplifying the integration of tests into the CI/CD process.

For example, JUnit for Java or pytest for Python enable the creation of unit tests that automatically check individual parts of the code for correctness.
