Robolectricunit testing失败,Android Studio 2.3更新

我所有的unit testing开始抛出这个错误:

它工作得很好。 我改变的唯一的事情是我更新了Android Studio到2.3和gradle插件到2.3。 到目前为止,我通过在每个testing的运行configurationpath中手动写下$MODULE_DIR$来修复它。 但是真的很烦人,每次都写下来。 有没有人经历过这样的事情?

默认设置它,所以你创build的每一个新的testingconfiguration都会inheritance它:

默认设置

运行 > 编辑configuration… > 默认值 > Android JUnit

工作目录中input: $MODULE_DIR$

Android工作室正在查看APP文件夹以运行AS 2.3版本的testing。 如果您有自定义Roboelectric Runner扩展RoboelectricTestRunner,则可以覆盖其中的工作目录,而不是每次都从编辑configuration中设置WORKING DIR。

这是我的代码。

公共类CustomRobolectricRunner扩展了RobolectricTestRunner {
