Question

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

我在想有没有办法在UI automator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位置。请帮忙。

Answer 1

我以前习惯使用运行时方法在测试setUp（）/ tearDown（）中注入shell命令，但是当我切换到UIAutomator 2.0和Gradle时它停止了工作。

如果您使用API 21（棒棒糖）及以上版本可以，Google会为我们提供此API：

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

这种方法适合我。来源：

Answer 2

这是有效的代码。在运行UiAutomator测试之前，我已将脚本文件“command.sh”复制到外部SD卡。

代码不需要任何root权限。

package ui;
import java.io.File;
import java.io.IOException;
import android.os.RemoteException;
import com.android.uiautomator.core.UiDevice;
import com.android.uiautomator.core.UiObjectNotFoundException;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

public class SampleCode extends UiAutomatorTestCase {
    public void testHome() throws RemoteException,
        UiObjectNotFoundException {

    // press Home
    UiDevice mydevice = getUiDevice();
    if (!mydevice.isScreenOn()) {
        mydevice.wakeUp();
    }
    mydevice.pressHome();

    // Script path
    String filePath = "/mnt/sdcard_ext/command.sh";
    File command = new File(filePath);
    command.setExecutable(true);

    // Run command
    Process p = null;       
    try {
        Runtime.getRuntime().exec(
                "/system/bin/sh /mnt/sdcard_ext/command.sh");
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (p != null)
            p.destroy();
    }

 }

}

这是“command.sh”的内容，输出将被写入外部SD卡上的文件

SDCARD="/mnt/sdcard_ext/"
LOG="$SDCARD/testlog.txt"
logcat -d >> $LOG

尝试这种方法 -

public String shell(String cmd) {

    String s = null;
    try {
        Process p = Runtime.getRuntime().exec(cmd);

        BufferedReader stdInput = new BufferedReader(new InputStreamReader(
                p.getInputStream()));

        BufferedReader stdError = new BufferedReader(new InputStreamReader(
                p.getErrorStream()));

        // read the output from the cmd
        String result = "";
        while ((s = stdInput.readLine()) != null) {
            result = result + s + "\n";
        }

        // read any errors from the attempted comd
        while ((s = stdError.readLine()) != null) {
            System.out.println(s);
        }
        return result;

    } catch (IOException e) {
        System.out.println("exception here's what I know: ");
        e.printStackTrace();
        return "Exception occurred";
    }
}

现在你打电话 -

String ls= Shell("ls");
