我有一个要与Jenkins建立的Android应用程序。我已经使用Android Emulator Plugin启动了一个模拟器，并使用gradle脚本构建了该项目，但是我无法让它运行我使用AndroidJUnitRunner编写的简单测试。

我从詹金斯的输出看起来像这样...

+ adb shell pm list instrumentation
instrumentation:com.android.emulator.connectivity.test/android.test.InstrumentationTestRunner (target=com.android.emulator.connectivity.test)
instrumentation:com.android.emulator.gps.test/android.test.InstrumentationTestRunner (target=com.android.emulator.gps.test)
instrumentation:com.android.smoketest.tests/com.android.smoketest.SmokeTestRunner (target=com.android.smoketest)
instrumentation:com.android.smoketest.tests/android.test.InstrumentationTestRunner (target=com.android.smoketest)
instrumentation:com.example.android.apis/.app.LocalSampleInstrumentation (target=com.example.android.apis)
[Short Sounds] $ /bin/sh -xe /tmp/hudson7415767398022941631.sh
+ adb shell am instrument -w com.sloths.speedy.shortsounds/android.support.test.runner.AndroidJUnitRunner
INSTRUMENTATION_STATUS: id=ActivityManagerService
INSTRUMENTATION_STATUS: Error=Unable to find instrumentation info for: ComponentInfo{com.sloths.speedy.shortsounds/android.support.test.runner.AndroidJUnitRunner}
INSTRUMENTATION_STATUS_CODE: -1
android.util.AndroidException: INSTRUMENTATION_FAILED: com.sloths.speedy.shortsounds/android.support.test.runner.AndroidJUnitRunner

如您所见，我已经通过shell命令列出了adb工具。在列表中找不到AndroidJUnitRunner。我是半积极的，应该在那里可以正常工作。

我在build.gradle文件中添加了适当的配置标签...即...

defaultConfig { 
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

我还添加了这些依赖项。

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    ...
    androidTestCompile 'com.android.support.test:runner:0.2'
    // Set this dependency to use JUnit 4 rules
    androidTestCompile 'com.android.support.test:rules:0.2'
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.1'
} …
