An example application that uses a contacts library with a brittle test.

app.go

package app

import "contacts"

func GreatSpeaker() *Person {
	return contacts.Me()
}

func TestMyName(t *testing.T) {
	got := GreatSpeaker()
	want := &Person{
		FirstName: "Ross",
		LastName:  "Light",
	}
	if !reflect.DeepEqual(got, want) {
		t.Errorf("got %+v; want %+v", got, want)
	}
}
