@MediumTest
public void testSendMessageToReceiverActivity() {
    final Button sendToReceiverButton = (Button) 
            mSenderActivity.findViewById(R.id.send_message_button);

    final EditText senderMessageEditText = (EditText) 
            mSenderActivity.findViewById(R.id.message_input_edit_text);

    // Set up an ActivityMonitor
    ...

    // Send string input value
    ...

    // Validate that ReceiverActivity is started
    ...

    // Validate that ReceiverActivity has the correct data
    ...

    // Remove the ActivityMonitor
    ...
