Testing

func TestMock(t *testing.T) {
	assert := assert.New(t)
	require := require.New(t)

	service, client, err := proto.NewHyperServiceMock()
	if err != nil {
		require.NoError(err)
	}
	defer service.Stop()

	service.On(proto.DesktopList, mock.Anything, &proto.DesktopListRequest{}).Return((*proto.DesktopListResponse)(nil), status.Error(codes.Internal, "custom error! :D"))

	list, err := client.DesktopList(context.Background(), &proto.DesktopListRequest{})

	assert.EqualError(err, status.Error(codes.Internal, "custom error! :D").Error())
	assert.Nil(list)
