type Messenger interface {
	GetMessage() (*BuildServiceRequest, error)
	DeleteMessage() error
}

type MessengerImpl struct {
	session *sqsiface.SQSAPI // Need to use amazon's interface
	message *sqs.Message
}

// In your tests you need to mock out session

type MockedSession struct {
  sqsiface.SQSAPI
  // Mocked functions from the Real amazon api
  Response sqs.RecieveMessageOutput
}

// Mock out the functions declared underneath stubbed session
func (m MockedSession) ReceiveMessage(input *sqs.RecieveMessageInput)() { return bullshit response }

// Create a test to use your real code and inject the mocked session
func Test(t *testing.T) {
  queue := MessengerImpl {
     session: MockedSession{Response:} //inject client here
  }
  queue.GetMessage() // hits your real code and returns values
}
