ActivityTestRule is not imported

Issue

I have added below dependencies in gradle:

But still ActivityTestRule can not be imported, showing error

Solution

It looks like you're using the old dependencies from Espresso 2.2.2. For the current version (Espresso 3.0.2), the ActivityTestRule dependency is found in

androidTestImplementation 'com.android.support.test:rules:1.0.2'

It would probably be a good idea to check the official documentation to make sure that the rest of the dependencies are set up correctly as well, but here's what I'd recommend to get started with Espresso.

In the dependencies section of app/build.gradle, add this:

androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
androidTestImplementation 'com.android.support.test:rules:1.0.2'
androidTestImplementation 'com.android.support.test:runner:1.0.2'

In the defaultConfig section of app/build.gradle, add this:

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

If you encounter other similar problems, the documentation includes a long list of other gradle dependencies that might have what you need, but what I've listed above should be enough to get you started.
