使用浓缩咖啡进行活动测试中的NoClassDefFoundError

Question

I'm trying to get activity testing going using espresso but I'm getting a NoClassDefFoundError (see stack out put below). I've tried a few things that I saw on stackoverflow but none worked for me

您有一个testApplicationId "com.example.test"是故意的，不应有“ test”后缀：

totestApplicationId "com.example.test.test"
