What types of testing are used to verify server-side applications?

The following types of testing are usually used to verify the server-side of applications:

• Unit Testing — testing individual functions or methods without dependence on external systems.
• Integration Testing — testing the interaction between modules and components.
• Functional Testing — verifying that functionality meets requirements.
• API Testing — testing REST or RPC interfaces for correctness and stability.
• Load Testing — testing server behavior under high load.
• Security Testing — checking for vulnerabilities and data protection.

In Go, the testing package is often used for unit testing, and third-party tools and frameworks are used for integration and load testing.
