错误UIAuitomator代码

Question

我的代码如下，

package com.example.automatorapp.test; 

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

public class Try2 extends UiAutomatorTestCase 
{ 

public void demo() throws UiObjectNotFoundException 
{ 


    getUiDevice().pressHome(); 
} 



} 

，误差...

我的MainActivity没有problem.It工作fine.but这一测试案例给出一些错误。并且可以告诉我如何添加uautomator.jar的javadoc。因为我无法找到uautomator的javadoc的apk。

Answer 1

测试用例需要有public void test...() { ... }

你的代码标准的JUnit 3风格的方法签名的demo()方法一旦你添加前缀如下测试，testdemo()那么测试是发现和执行。

为了完整起见，这里是测试运行时2的区别。首先，什么本质上是一个与方法public void demo()

UIAutomatorExample$ adb shell uiautomator runtest UIAutomatorExample.jar -c com.example.automatoapp.test.Try2 
INSTRUMENTATION_STATUS: stream= 
Test results for WatcherResultPrinter= 
Time: 0.0 

OK (0 tests) 

而且一次你的代码的方法已经被正确地命名public void testdemo()

UIAutomatorExample$ adb shell uiautomator runtest UIAutomatorExample.jar -c com.example.automatoapp.test.Try2 
INSTRUMENTATION_STATUS: current=1 
INSTRUMENTATION_STATUS: id=UiAutomatorTestRunner 
INSTRUMENTATION_STATUS: class=com.example.automatoapp.test.Try2 
INSTRUMENTATION_STATUS: stream= 
com.example.automatoapp.test.Try2: 
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.Try2 
INSTRUMENTATION_STATUS: stream=. 
INSTRUMENTATION_STATUS: numtests=1 
INSTRUMENTATION_STATUS: test=testdemo 
INSTRUMENTATION_STATUS_CODE: 0 
INSTRUMENTATION_STATUS: stream= 
Test results for WatcherResultPrinter=. 
Time: 1.53 

OK (1 test) 

而这里的示例代码修正版本：

package com.example.automatoapp.test; 

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

public class Try2 extends UiAutomatorTestCase 
{ 
    public void testdemo() throws UiObjectNotFoundException 
    { 
     getUiDevice().pressHome(); 
    } 
}
