UIAutomator中的RunTimeException在Android中测试

其实我是UIautomator测试的新手。我做了一个需要测试的课程。任何人都可以告诉我一些步骤，我怎样才能让我的UIAutomator测试用例课程？我已经得到了一些错误，如...UIAutomator中的RunTimeException在Android中测试

和我的代码是...

 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有人帮我吗？

的问题是在你的构造，'超（）'不能与空值传递。 – NullPointer 2013-03-26 10:08:03

但是当我在构造函数中传递一些值时，它会给我错误？ – Aditya 2013-03-26 10:08:34

只需删除您的构造函数，就不需要它。 – NullPointer 2013-03-26 10:12:10

由于空指针已经指出，构造函数需要删除。

这里是修改后的代码（我已编译和成功运行）

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(); 
    } 
}

对于下文中，所有的命令从命令行运行，而不是在一个IDE

下面是如何我编译&的UIAutomator码推送到设备 ant clean build && adb push bin/UIAutomatorExample.jar /data/local/tmp/

我怎么跑“你的”测试 adb shell uiautomator runtest UIAutomatorExample.jar -c com.example.automatoapp.test.Test2

为了完整这里是输出：

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

OK (1 test)
