Android Instrumentation测试中的ClassNotFoundException

Question

我正在尝试为我的应用程序编写检测测试，但出现此错误。我已经看了互联网上几乎所有的答案，但没有一个对我有用。

我已附上我的gradle文件并在此处进行测试以供参考

java.lang.RuntimeException: Unable to instantiate instrumentation ComponentInfo{com.vuclip.viu.test/android.support.test.runner.AndroidJUnitRunner}: java.lang.ClassNotFoundException: Didn't find class "android.support.test.runner.AndroidJUnitRunner" on path: DexPathList[[],nativeLibraryDirectories=[/system/lib64, /vendor/lib64]]
