android – 从命令行测试UiAutomator 2.0

我正在尝试使用 Android UIAutomator进行一些简单的测试,我知道它需要由Gradle自UIAutomator 2.0构建,我可以运行我的简单测试,它只通过Android studio或命令行按下主页按钮“gradlew .bat cC“,我想知道如何用adb命令运行它？

我试过了

adb sHell am instrument -w test.simple.uiatest/android.test.instrumentationTestRunner

按照建议here,但我明白了

instrUMENTATION_STATUS: id=Activitymanagerservice
instrUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponenTinfo{test.simple.uiatest/android.test.instrumentationTestRunner}
instrUMENTATION_status_code: -1
android.util.AndroidException: instrUMENTATION_Failed: test.simple.uiatest/android.test.instrumentationTestRunner
    at com.android.commands.am.Am.runinstrument(Am.java:951)
    at com.android.commands.am.Am.onRun(Am.java:316)
    at com.android.internal.os.baseCommand.run(BaseCommand.java:47)

    at com.android.internal.os.RuntimeInit.nativeFinishInit(Native Method)
    at com.android.internal.os.RuntimeInit.main(RuntimeInit.java:250)

下面是我的代码片段和build.gradle,我做错了什么？

package test.simple.uiatest;

import android.support.test.uiautomator.UiDevice;
import android.test.instrumentationTESTCase;

public class ApplicationTest extends instrumentationTESTCase {
    private UiDevice theDevice;

    @Override
    public void setUp() throws Exception {
        super.setUp();
        theDevice = UiDevice.geTinstance(getinstrumentation());

        theDevice.pressHome();
    }

    public void testName() throws Exception {
        theDevice.pressHome();
    }
}

的build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.0 rc2"

    defaultConfig {
        testinstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

            proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
        }
    }

    packagingOptions {
        exclude 'LICENSE.txt'
    }
}

    compile fileTree(dir: 'libs',include: ['*.jar'])
