type Reporter ¶

type Reporter struct {
	T *testing.T
}

Reporter wraps a *testing.T, and provides a more useful failure mode when interacting with gomock.Controller.

For example, consider:

func TestMyThing(t *testing.T) {
  mockCtrl := gomock.NewController(t)
  defer mockCtrl.Finish()
  mockObj := something.NewMockMyInterface(mockCtrl)
  go func() {
    mockObj.SomeMethod(4, "blah")
  }
}

It hangs without any indication that it's missing an EXPECT() on `mockObj`. Providing the Reporter to the gomock.Controller ctor avoids this, and terminates with useful feedback. i.e.

func TestMyThing(t *testing.T) {
  mockCtrl := gomock.NewController(test.Reporter{t})
  defer mockCtrl.Finish()
  mockObj := something.NewMockMyInterface(mockCtrl)
  go func() {
    mockObj.SomeMethod(4, "blah") // crashes the test now
  }
}
