What methods and tools did you use to verify the correctness and quality of your code?

To verify the correctness and quality of Go code, the following methods and tools are usually used:

• Testing: writing unit tests using the testing package. It allows testing individual functions and methods.
• Test coverage: the command go test -cover shows what percentage of the code is covered by tests.
• Static analysis: golint for style checking, go vet for identifying potential errors.
• Formatting: gofmt automatically formats code according to Go standards.
• Profiling and debugging: pprof for performance analysis.

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("Expected 5, got %d", result)
    }
}
