我正在使用Jake的Android单元测试插件gradle：https://github.com/JakeWharton/gradle-android-test-plugin
我的build. gradle看起来像这样：
dependencies {
// analytics
compile('com.crittercism:crittercism-android:3.0.11')
// retrofit
compile('com.squareup.retrofit:retrofit:1.2.2')
compile('com.squareup.okhttp:okhttp:1.2.1')

compile('com.squareup.dagger:dagger-compiler:1.1.0')
// compatibility
compile('android.compatibility:android-support:v4-r13')
compile('com.actionbarsherlock:actionbarsherlock:4.4.0@aar')
// Picasso

// Otto

// Tests

testCompile 'org.robolectric:robolectric:2.2'
testCompile 'org.powermock:powermock-api-mockito:1.5.1'
testCompile 'org.easytesting:fest-assert-core:2.0M10'
}
不幸的是，我无法运行Android Studio的所有或特定单元测试。我得到错误：

这是正确的，因为运行命令行不包括我的JUnit依赖项：

我想知道是否有人能够在Android Studio中运行单元测试？如果可能，如何做到这一点？
只需在 /src下添加名为InstrentTest的文件夹，它应该有/java
然后扩展类ActivityTestCase（或任何其他android单元测试类），例如
package com.example.app.test;
import android.test.ActivityTestCase;
import junit.framework.Assert;
public class MainActivityTest extends ActivityTestCase {
public void testHappy(){
Assert.assertTrue(true);
}
}
右键单击绿色java目录并选择运行所有测试，您应该得到以下内容：
好运
AS 1.1更新，android gradle插件1.1
最后，这是可能的，没有很多技巧。这里是一个项目的例子，展示了如何在Android Studio v1.1和android gradle plugin v1.1中设置Robolectra测试：https://github.com/nenick/AndroidStudioAndRobolectric
您还可以找到可能的问题和解决方法。是的，Robolec的很复杂，没有得到Google的官方支持，所以它仍然存在一些问题。但大多数情况下，它都有效，并为您的项目带来巨大的价值。
我还鼓励您开始使用Robolectricv3。它几乎已经发布并且足够稳定。
AS 0. x和1.0x的旧答案以及1.1以下的android gradle插件版本
在朋友的帮助下，我设法做到了。
因此，基本上您需要进行下一步更改以在Android Studio中运行Robolec的单元测试：
-classpath"对我来说，新的类路径的开始是这样的：
/Users/emartynov/Development/Projects/work/android.project/build/test-classes:/Users/emartynov/.gradle/caches/modules-2/files-2.1/junit/junit/4.11/4e031bb61df09069aeb2bffb4019e7a5034a4ee0/junit-4.11.jar
问题：

我遇到了这个问题并找到了一个解决方案-将分解包（. aar）中的类.jar包含在构建文件夹中。不过，我认为这对在.aar依赖项中查找资源没有帮助。
testCompile fileTree(dir: "$project.buildDir/exploded-bundles", include: "**/classes.jar")
编辑：自Android Gradle构建工具0.9.0以来，依赖项已更改为：
androidTestCompile fileTree(dir: "$project.buildDir/exploded-aar", include: "**/classes.jar")
编辑2：自Android Gradle构建工具0.10.0以来，依赖项已更改为：
androidTestCompile fileTree(dir: "$project.buildDir/../../build/exploded-aar", include: "**/classes.jar")
注意：根据您的项目结构，相对路径可能会有所不同。
