在Android Studio上测试Robolectric时出错

我有一个在android studio 0.8.1和gradle上运行的项目，运行起来没有任何问题，但是如果我尝试在我的项目中运行一些测试，我会得到以下错误：

Error:Execution failed for task ':app:dexDebugTest'.

我的build.gradle看起来像：

谢谢

试着用这个替换你的

androidTestCompile('org.robolectric:robolectric:2.3') {

你为什么投反对票？我如何改进我的问题？我是这里的活跃成员，所以我不会简单地否决我不能回答的每个问题，更糟糕的是，没有任何解释。现在我找不到类：“FirstActivityTest”。有什么想法吗？@LeonardoFerrari是FirstActivityTest您的一个测试类，还是来自依赖项？这很奇怪。尝试将其添加到gradle配置中。robolectric{include'**/*Test.class'}您是否试图从命令行或android studio构建和运行测试？从android studio运行JUnit测试。我试着给你反馈。谢谢你的耐心！
