我在用着：

  • 安卓工作室 1.1.0
  • 摇篮 2.2.1
  • Gradle 的 Android 插件：1.1.0

我们最近搬到了 Android Studio，我们正在努力使我们的仪器测试工作。但是，当我运行测试时，它给了我错误

运行测试测试运行开始测试运行失败：找不到仪器信息：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。请看下面的配置：

应用类：

public class XxxApp extends MultiDexApplication
{
...
}

原始问题中描述的确切情况可能与旧版本的工具有关。

我在这里添加我的经验，因为这是使用... Unable to find ... ComponentInfo ...错误消息进行搜索时谷歌的第一个点击。

使用最新版本的工具和 android 插件，您似乎不需要任何其他东西build.gradle来获得测试multiDexEnabled true：

...
android {
    ...
    defaultConfig {
        ...
        testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner"
    }
}

（我有com.android.tools.build:gradle:1.5.0）

I am not sure what compile project(':Common') is, most likely an Android Library; however, besides that library there is no reason for you to use MultiDex.

In order to use InstrumentationTestRunner you need Instrumentation Tests in the androidTest folder.

I would highly suggest you move your "Eclipse-based" project structure to Android Studio's default Gradle structure: "src/main/java, src/test/java and src/androidTest/java"

Top build.gradle:

dependencies {
    classpath 'com.android.tools.build:gradle:1.1.3' // <-- Updated
}

App build.gradle:

apply plugin: 'com.android.application'

dependencies {
    compile project(':Common') // <-- Not sure what this is
    compile 'com.google.android.gms:play-services-maps:6.5.87'
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'org.apache.commons:commons-lang3:3.3.2'
    compile 'com.google.code.gson:gson:2.3.1'
    compile 'joda-time:joda-time:2.7'
    compile 'org.roboguice:roboguice:2.0' // <-- There is a newer versoin, but might break your current code
    compile 'com.google.zxing:core:3.2.0'
    androidTestCompile 'com.google.dexmaker:dexmaker:1.+'
    androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.+'
    androidTestCompile 'junit:junit:4.12'
    androidTestCompile 'org.hamcrest:hamcrest-library:1.3'
    androidTestCompile 'org.mockito:mockito-core:1.9.5'
}

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.0"
    enforceUniquePackageName false

    dexOptions {
