我正在使用：
我们最近搬到了Android Studio，我们正在努力让我们的仪器测试工作。但是当我运行测试时，它会给我错误
运行测试 测试运行startedTest运行失败：无法找到以下内容的检测信息：ComponentInfo {com.xxx.xxx.test / android.test.InstrumentationTestRunner} 空测试套件。
我不确定我在这里做错了什么。请参阅下面的配置：

原始问题中描述的确切情况可能与较旧版本的工具有关。
我在这里添加了我的经验，因为这是使用... Unable to find ... ComponentInfo ...错误消息进行搜索时Google首次点击之一。
使用最新版本的工具和Android插件，您似乎除了build.gradle之后不需要其他任何操作才能让测试与multiDexEnabled true一起使用：
...
android {
...
defaultConfig {
...
testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner"
}
}
（我有com.android.tools.build:gradle:1.5.0）

我不确定compile project(':Common')是什么，很可能是Android库;但是，除了该库之外，您没有理由使用MultiDex。
要使用InstrumentationTestRunner，您需要在androidTest文件夹中进行检测测试。
我强烈建议您将“基于Eclipse”的项目结构移动到Android Studio的默认Gradle结构：“src/main/java，src/test/java和src/androidTest/java”
