停止按鈕不停止當前android單元測試

Question

需要一種解決方法來停止在ADT上運行在AVD上的長時間單元測試。在JUnit視圖中的停止按鈕不起作用，在調試視圖中都沒有停止按鈕。即使它打印該VM已終止。例如：

public class StopTest extends AndroidTestCase { 

    public void testSleep() throws Exception { 
     Thread.sleep(20000); 
    } 
} 

可能的解決方案：

顯示設備屏幕上的取消按鈕。

我設法用我的測試項目中的按鈕創建一個新的活動。不幸的是，測試套件是在我測試的應用程序的上下文中執行的。所以，要開始這個活動，我需要編輯我不想要的應用程序清單。所以我將這個活動添加到測試清單並從InstrumentationTestCase.getInstrumentation().getContext()開始。

用這個按鈕我的活動出現在屏幕上，但它在另一個進程中啓動。現在我需要從活動向我測試的應用程序發送消息。

不想將服務添加到我的應用程序，因爲，正如我所說的，我不想編輯應用程序清單。

是否可以發送Binder到活動並使用它發回消息？

在setUp()我用一個按鈕開始活動。按下後，我會回覆廣播，並在接收器中撥打System.exit()。
