Overview

Go comes with a lightweight test framework that includes the go test command and the testing package.

The tests live in *_test.go files.

Also see external test packages.

TO DEPLETE

Writing a Unit Test

  • Write a _test.go test file. They should belong to the same package as the tested code. These files are ignored by the compiler and only compiled and executed when go test is run.
  • Import "testing"
  • Tests are identified as functions starting with Test_... and taking an argument (t *testing.T).
package blue

import "testing"

func TestBlue(t *testing.T) {
    ...
    t.Error("expected this, got ", ...)
}

Then

go test

The command will look for any tests in any of the files in the current folder and run them.
