android - 如何从 UIAutomator 运行 "adb commands"

Question

所以我有一个 UIAutomator 测试脚本，在测试执行期间我希望它运行一些 adb 命令。我该怎么做？

我在想有没有办法在 UI 自动化器类中调用脚本？或者有没有办法直接执行“adb 命令”？

这是我的代码:

package com.uia.example.my;


import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

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

public class ADBCommandTest extends UiAutomatorTestCase{
    public void testDemo() throws UiObjectNotFoundException{

        System.out.println("Entering the shell script");
        try {
            ProcessBuilder pb = new ProcessBuilder("./run.sh");
            Process p = pb.start();
            BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
            String line = null; 
                while ((line = reader.readLine()) != null)
                {
                    System.out.println(line);
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

    }

}

这是我得到的错误:

我将 run.sh 脚本文件放在我的类文件所在的同一位置。请帮忙。

我以前使用运行时方法在测试 setUp()/tearDown() 中注入(inject) shell 命令，但是当我切换到 UIAutomator 2.0 和 Gradle 时，它​​对我不起作用。

如果您可以使用 API 21 (lollipop) 及更高版本，Google 会为我们提供此 API:

InstrumentationRegistry.getInstrumentation().getUiAutomation().executeShellCommand("pm clear " + Constants.PACKAGE_NAME);

此方法适用于我的用例。来源:
