In Go, the standard testing package, which is built into the language and requires no additional dependencies, is most commonly used for unit testing. It allows writing tests in files with the suffix _test.go and running them with the command go test.

For more convenient writing and organization of tests, the following are often used:

• testify — a library with convenient assertions and mocks.
• gomock — for creating mock objects.
• httptest — for testing HTTP servers.

Example of a simple test using testing:

func TestSum(t *testing.T) {
    result := Sum(2, 3)
    if result != 5 {
        t.Errorf("Expected 5, got %d", result)
    }
}

Thus, the standard testing package is the main tool, and additional libraries help to write more expressive and convenient tests.
