Files

Test file should be place in the package directory and should be name using the following convention :

• repo : github.com/go/pkg
• package : github.com/go/pkg/example
• package file : example/pkg.go
• test file : exemple/pkg_test.go

Run

go test github.com/go/pkg/package

fmt.Println is not working

Gniagniagnia, use

t.Log()

or

t.Logf()

also,

go test github.com/go/pkg/package -v

How to fail

Mark test as failed (next tests executed)

t.Fail()

Mark test as failed AND exit

t.FailNow()

Print and mark test as failed

t.Error()

or

t.Errorf()

Print, mark test as failed AND exit

t.Fatal()

or

t.Fatalf()

I don't want my tests to be messy (kudos @athoune)

Assert

Shit, i want to disable my oauth test on my CI

if os.Getenv("DRONE") == "true" {
	t.Skip("Skipping test in CI environment")
}

Short mode

This test is too long ? Skip it !

if testing.Short() {
    t.Skip("Skipping test in short mode")
}

go test github.com/go/pkg/package --short

Cleanup test cache

go clean -testcache
