如何配置简单的android工作室来运行JUnit测试

Question

我正在运行Android工作室的JUnit测试，这太棒了。

为了做到这一点，我只好打了一下，并添加以下到VM选项，因为添加的junit 4.12至依赖于项目结构的应用没有工作的。

我的问题是：为什么，我做错了什么？

-ea -classpath "C:\Users\obfuscated\.gradle\caches\modules-2\files-2.1\junit\junit\4.12\2973d150c0dc1fefe998f834810d68f278ea58ec\junit-4.12.jar;D:\Program Files\Android\Android Studio\lib\idea_rt.jar;D:\Program Files\Android\Android Studio\plugins\junit\lib\junit-rt.jar;D:\Android\sdk\platforms\android-21\android.jar;D:\Android\sdk\platforms\android-21\data\res;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\classes\test\debug;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\classes\debug;C:\Users\obfuscated\.gradle\caches\modules-2\files-2.1\org.objenesis\objenesis\1.0\9b473564e792c2bdf1449da1f0b1b5bff9805704\objenesis-1.0.jar;C:\Users\obfuscated\.gradle\caches\modules-2\files-2.1\org.hamcrest\hamcrest-core\1.3\42a25dc3219429f0e5d060061f71acb49bf010a0\hamcrest-core-1.3.jar;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\exploded-aar\com.android.support\support-v4\21.0.3\libs\internal_impl-21.0.3.jar;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\exploded-aar\com.android.support\support-v4\21.0.3\classes.jar;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\exploded-aar\com.android.support\support-v4\21.0.3\res;D:\Android\sdk\extras\android\m2repository\com\android\support\support-annotations\21.0.3\support-annotations-21.0.3.jar;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\exploded-aar\com.android.support\support-v13\21.0.2\libs\internal_impl-21.0.2.jar;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\exploded-aar\com.android.support\support-v13\21.0.2\classes.jar;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\exploded-aar\com.android.support\support-v13\21.0.2\res;C:\Users\obfuscated\.gradle\caches\modules-2\files-2.1\org.mockito\mockito-core\1.9.5\c3264abeea62c4d2f367e21484fbb40c7e256393\mockito-core-1.9.5.jar;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\exploded-aar\com.android.support\cardview-v7\21.0.2\res;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\exploded-aar\com.android.support\cardview-v7\21.0.2\classes.jar;D:\Android\projets\AndroidStudioProjects\ElevationDrag\Application\build\intermediates\mockable-android-21.jar"

如果我按照给定的here指示，我发现自己有以下错误：

Answer 1

的Android类在设备或仿真器中运行。如果没有，你需要一些手段来嘲笑的android.jar
