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.
