问题描述

我所有的单元测试都开始抛出这个错误:

All my Unit Test started throwing this error:

它工作得很好.我唯一改变的是我将 Android Studio 更新到 2.3，将 gradle 插件更新到 2.3.到目前为止，我通过在每个测试的运行配置路径中手动写下 $MODULE_DIR$ 来修复它.但是每次都写下来真的很烦.有没有人遇到过这样的情况?

It worked just fine. The only thing that I changed is that I updated Android Studio to 2.3 and the gradle plugin to 2.3. So far I fix it by manually writing down $MODULE_DIR$ in each test's Run Configuration path. But is really annoying write it down every time. Has anyone experience something like this?

推荐答案

默认设置，这样你创建的每一个新的测试配置都会继承它:

Set it by default, so every new test configuration that you create will inherit it:

运行 > 编辑配置... > 默认 > Android JUnit

在工作目录中输入:$MODULE_DIR$
