What types of testing can you name and explain their features?

Main types of testing:

• Unit Testing — testing individual functions or classes for correctness. Usually isolated from external dependencies.

• Integration Testing — testing the interaction between modules or system components.

• Functional Testing — testing the application's functionality against requirements.

• System Testing — testing the entire system in conditions close to real-world scenarios.

• Acceptance Testing — verifying whether the system meets the expectations and requirements of the customer.

• Regression Testing — ensuring that changes in the code do not break existing functionality.

• Load Testing — testing system behavior under high load.

• Security Testing — testing for vulnerabilities and data protection.

Each type of testing has its own purpose and scope, which helps improve the quality and reliability of the software product.
