Espresso：错误包不存在

Question

我正在尝试将Espresso添加为我的Android项目的测试框架，并在运行样本测试时遇到以下运行时错误。

error: package android.support.test.rule does not exist

error: package android.support.test.runner does not exist

我的文件夹结构如下：

app/src/androidTest/java/com/[identifier]/support/[app_folders] app/src/com/java/com/[identifier]/support/[app_folders]

我的build.gradle看起来像以下减去编辑不相关的陈述。
