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();
}



 }

，错误是......

我的MainActivity没有问题。它工作正常。但是这个测试用例给出了一些错误。你可以告诉我如何添加uiautomator.jar的javadocs。因为我无法找到uiautomator的javadoc的apk？

Answer 1

测试用例需要具有public void test...() { ... }

的标准junit 3样式方法签名

您的代码的方法为demo()按照以下方式添加前缀测试testdemo()后，即可找到并执行测试。

为了完整性，这是测试运行时2之间的差异。首先，使用方法public void demo()

实际上是您的代码

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)

一旦将方法正确地命名为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)

以下是示例代码的更正版本：

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();
    }
}

UIAuitomator代码出错
