What are the main types of testing in the software quality assurance process?

Main types of testing in software quality assurance:

• Unit Testing — testing individual functions or components.
• Integration Testing — testing the interaction between modules.
• System Testing — testing the entire system as a whole.
• Acceptance Testing — verifying that the system meets the customer's requirements.
• Regression Testing — ensuring that new changes do not break existing functionality.
• Load Testing — testing the system's behavior under high load.
• Security Testing — identifying vulnerabilities.

Each type of testing addresses its own tasks and together they ensure the quality and stability of the product.
