这也可能与当我点击 Dock 中打开的 Android Studio 图标时出现错误 no JVM was found 但我可以通过终端打开它没问题.

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.

这与一个全新的 android studio 项目相同，默认 applicationTest 尝试运行.

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

推荐答案

那么两件事

首先，如果您尝试在 Yosemite 升级时打开 Android Studio 并显示未找到 JVM"，则您需要为 osx 安装 java 6 此处 因为 Android 需要 java 1.6 而不是 java 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，我发现的异常是因为它试图运行 JUnit，就好像我想通过 Java 标准控制台而不是通过 Android 运行一样.

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.

不要使用带有黑色箭头的 Java 测试，使用 Android 测试中的单元测试并删除 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.

您的配置应该如下所示，然后您可以右键单击单个测试并像平常一样运行它们.

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