android - UIAuitomator 代码错误

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。但是这个测试用例有一些错误。你能告诉我如何添加 uiautomator.jar 的 javadocs。因为我找不到 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

您的代码有一个方法 demo() 一旦您添加了如下前缀测试，testdemo() 就会找到并执行测试。

为了完整起见，这是运行测试时两者之间的区别。首先，使用方法 public void demo()

本质上是什么代码

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)

一旦方法被正确命名为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)

这里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();
    }
}
