Android：运行时错误，而UiTesting

Question

我想运行一个Ui测试，并且每次运行applicatoin它都会在控制台中提供以下错误并关闭正在运行的应用程序。我已经导入了uiautomator.jar，android.jar & JUnit4库。我使用Eclipse。我在这里错过了什么？

[2016年4月4日4时44分00秒 - UiTests]测试运行失败：仪表运行 失败，因为 '了java.lang.RuntimeException'

的TestClass

package android.support.v7.appcompat.test; 

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

public class DMTest extends UiAutomatorTestCase 
{ 
    public void testDemo() throws UiObjectNotFoundException 
    { 
     // setText 
     new UiObject(new UiSelector().description("edittext_brute")).setText("bazinga"); 

     // clickButton 
     //new UiObject(new UiSelector().description("button_done")).click(); 

     UiObject btDone = new UiObject(new UiSelector().description("button_done")); 
     btDone.click(); 
    } 

} 

清单

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="android.support.v7.appcompat.test" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk android:minSdkVersion="14" /> 

    <instrumentation 
    android:name="android.test.InstrumentationTestRunner" 
    android:targetPackage="com.example.sony.reel" /> 

    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" > 
     <uses-library android:name="android.test.runner" /> 
    </application> 

</manifest> 

编辑1：它让即使是testDemo（）构造

编辑2内没有代码相同的异常：logcat的

找不到测试类...

Android建议使用工作室为uiautomator测试项目和gradle建设。

对于您的情况，请尝试在测试类定义开始时添加@RunWith(AndroidJUnit4.class)注释。

如果您将此代码移至工作室，您的代码示例肯定会有效。或用ant进行编译并使用编译后的jar文件运行。
