What types of testing exist in the software verification process?

There are many types of software testing, the main ones are:

• Unit Testing — testing individual functions or classes.
• Integration Testing — testing the interaction between modules.
• Functional Testing — verifying that the functionality meets the requirements.
• System Testing — testing the entire system as a whole.
• Acceptance Testing — verifying the product's readiness for use by the customer.
• Regression Testing — ensuring that changes haven't broken existing functionality.
• Performance Testing — testing speed and stability.
• Security Testing — checking for vulnerabilities.

In Python, for unit testing, frameworks like unittest, pytest, and others are often used.
