Go provides the built-in testing package for tests.

Each test in Go is a function, with some special requirements:

• it must be in a file whose name ends in _test.go;
• the name of a test function must begin with the word Test;
• it has to accept a parameter whose type is *testing.T;
• they don’t return anything.

When all this requirements are satisfied, you can run the tests from the terminal with: go test
