Android Studio无法识别Espresso导入

我正在尝试使用Espresso编写测试用例.

我使用的是Android studio 1.5.1(稳定频道),Gradle插件1.5,Gradle 2.7.
问题是Android studio无法识别与Espresso(而不仅仅是)相关的任何导入

所以,我试图清理项目,重建,使缓存无效并重新启动,但没有.

我在我的app模块中添加了这些依赖项：

androidTESTCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
androidTESTCompile 'com.android.support:support-Annotations:23.1.1'
androidTESTCompile 'com.android.support.test:runner:0.4.1'
androidTESTCompile 'com.android.support.test:rules:0.4.1'

我在defaultConfig中添加了runner：

testinstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

我在AndroidTest文件夹下创建了测试套件类：

我做错了什么？

这是我的build.gradle的(部分)：
