Say you have a source file like so in hello.go:

	package somepackage 

	func Thing(str string) string {
		return "hello " + str
	}

Then you can issue tests for it by creating a hello_test.go in the same directory:

	package somepackage 

	import "testing"

	func Test_should_have_correct_result(t *testing.T) {
		if x:= Thing("a"); x!="hello a" {
			t.Error("I wanted hello a. I got: " + x)
		}
	}

Any functions in hello_test.go starting with Test will be run.

You can run all the tests by issuing this command in your source directory:

	go test
	// or 'go your/package/name test' if you're not in the source directory.
