这可能也与当我挖掘我的码头开放的Andr​​oid Studio图标我没有得到任何JVM发现错误，但我可以通过终端打开它没有问题。

it may also be related to when i tap the open Android Studio icon in my Dock i get the error no JVM was found but i can open it via Terminal no problem.

这是一样的默认applicationTest试图运行一个全新的机器人工作室的项目。

This is the same as a brand new android studio project with the default applicationTest trying to run.

推荐答案

所以两件事

首先，如果你试图打开Android Studio中的优山美地升级，它说没有找到JVM你需要安装java 6 OSX的此处由于Android需要Java 1.6和Java的不是1.6 +

First, if you try to open Android Studio on Yosemite upgrade and it says "No JVM found" you need to install the java 6 for osx here as Android requires java 1.6 and not java 1.6+.

第二，我发现了异常被造成的，因为它试图运行JUnit，如果我想通过Java标准控制台，而不是与Android运行。

Second, The Exception I found was caused because it was trying to run JUnit as if I wanted to run through java standard console instead of with Android.

不要使用Java测试包含一个黑色的箭头，使用Android的测试中的单元测试，并删除了JUnit配置的所有用途。

Do not use the Java test that contains a black with arrows, use the unit tests within a Android Tests and delete all uses of the JUnit configuration.

您的配置应该是这样的，那么你可以用鼠标点击一个测试，并像正常运行。

Your configuration should look like this, then you can right click on single tests and run them like normal.
