Have you had experience with automated testing in projects?

In Go projects, automated testing is usually implemented using the standard testing package. Experience may include:

• Writing unit tests for functions and methods using testing.T.
• Using test tables to check various input data.
• Running tests with the go test command.
• Using mocks and stubs to isolate components.
• Integration testing with external services.

Example of a simple test:

func Add(a, b int) int {
    return a + b
}

func TestAdd(t *testing.T) {
    result := Add(2, 3)
    if result != 5 {
        t.Errorf("Add(2, 3) = %d; want 5", result)
    }
}

This approach allows for quick error detection and maintaining code quality.
