UIAutomator中的RunTimeException在Android中測試

其實我是UIautomator測試的新手。我做了一個需要測試的課程。任何人都可以告訴我一些步驟，我怎樣才能讓我的UIAutomator測試用例課程？我已經得到了一些錯誤，如...UIAutomator中的RunTimeException在Android中測試

和我的代碼是...

 package com.example.automatorapp.test; 

    import com.android.uiautomator.core.UiObjectNotFoundException; 
    import com.android.uiautomator.testrunner.UiAutomatorTestCase; 

public class Test2 extends UiAutomatorTestCase 
{ 

    public Test2() 
    { 
    super(); 
    } 

    public void testDemo() throws UiObjectNotFoundException 
    { 

     getUiDevice().pressHome(); 

    } 


}

PLZ有人幫我嗎？

的問題是在你的構造，'超（）'不能與空值傳遞。 – NullPointer 2013-03-26 10:08:03

但是當我在構造函數中傳遞一些值時，它會給我錯誤？ – Aditya 2013-03-26 10:08:34

只需刪除您的構造函數，就不需要它。 – NullPointer 2013-03-26 10:12:10

由於空指針已經指出，構造函數需要刪除。

這裏是修改後的代碼（我已編譯和成功運行）

package com.example.automatoapp.test; 

import com.android.uiautomator.core.UiObjectNotFoundException; 
import com.android.uiautomator.testrunner.UiAutomatorTestCase; 


public class Test2 extends UiAutomatorTestCase 
{ 
    public void testDemo() throws UiObjectNotFoundException 
    { 
     getUiDevice().pressHome(); 
    } 
}

對於下文中，所有的命令從命令行運行，而不是在一個IDE

下面是如何我編譯&的UIAutomator碼推送到設備 ant clean build && adb push bin/UIAutomatorExample.jar /data/local/tmp/

我怎麼跑「你的」測試 adb shell uiautomator runtest UIAutomatorExample.jar -c com.example.automatoapp.test.Test2

爲了完整這裏是輸出：

INSTRUMENTATION_STATUS: current=1 
INSTRUMENTATION_STATUS: id=UiAutomatorTestRunner 
INSTRUMENTATION_STATUS: class=com.example.automatoapp.test.Test2 
INSTRUMENTATION_STATUS: stream= 
com.example.automatoapp.test.Test2: 
INSTRUMENTATION_STATUS: numtests=1 
INSTRUMENTATION_STATUS: test=testDemo 
INSTRUMENTATION_STATUS_CODE: 1 
INSTRUMENTATION_STATUS: current=1 
INSTRUMENTATION_STATUS: id=UiAutomatorTestRunner 
INSTRUMENTATION_STATUS: class=com.example.automatoapp.test.Test2

INSTRUMENTATION_STATUS: test=testDemo 
INSTRUMENTATION_STATUS_CODE: 0 
INSTRUMENTATION_STATUS: stream= 
Test results for WatcherResultPrinter=.

OK (1 test) 


INSTRUMENTATION_STATUS_CODE: -1
