从命令行运行UiAutomator 2.0测试

Question

我正在尝试使用Android UIAutomator进行一些简单的测试。我知道自UIAutomator 2.0以来它需要通过Gradle构建，我可以通过Android Studio或命令行运行我的简单测试，只需通过“gradlew.bat cC”按home键即可。我想知道如何使用adb命令运行它？

我尝试过

adb shell am instrument -w test.simple.uiatest/android.test.InstrumentationTestRunner

根据这里的建议，但我遇到了问题。

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.commands.am.Am.main(Am.java:99)
    at com.android.internal.os.RuntimeInit.nativeFinishInit(Native Method)
    at com.android.internal.os.RuntimeInit.main(RuntimeInit.java:250)

以下是我的代码片段和build.gradle文件，我做错了什么吗？

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();
    }
}

build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.0 rc2"

    defaultConfig {
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        applicationId "test.simple.uiatest"
        minSdkVersion 21
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    packagingOptions {
        exclude 'LICENSE.txt'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile 'com.android.support.test:runner:0.2'
    androidTestCompile 'com.android.support.test:rules:0.2'
    androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.0'
}

Answer 1

您看到的错误会在测试APK未安装或am instrument ...命令中的<test_package>/<runner_class>错误时出现。

要列出可用于您设备的测试工具，可以运行adb shell pm list instrumentation指令。您应该会看到如下行:

instrumentation:test.simple.uiatest/android.test.InstrumentationTestRunner (target=simple.target.app)

如果您看不到匹配您测试的行，则需要安装测试APK。如果已安装，请仔细检查pm list instrumentation输出中的test.simple.uiatest/android.test.InstrumentationTestRunner部分是否与您的am instrument命令相匹配。

Answer 2

for your package, try this：

adb shell am instrument -w test.simple.uiatest.test/android.support.test.runner.AndroidJUnitRunner

请使用包test.simple.uiatest.test代替。

Answer 3

根据您发布的build.gradle文件，您应该使用"android.support.test.runner.AndroidJUnitRunner"

adb shell am instrument  -w test.simple.uiatest/android.support.test.runner.AndroidJUnitRunner
