Problems setting up junit & mockito in Android Studio

I want to setup my project for unit testing.

I tried to follow the instructions on Android's page:

// Unit testing dependencies
testCompile 'junit:junit:4.12'
// Set this dependency if you want to use Mockito
testCompile 'org.mockito:mockito-core:1.10.19'
// Set this dependency if you want to use Hamcrest matching
androidTestCompile 'org.hamcrest:hamcrest-library:1.1'

However, when doing that and creating a test, I get:

"Cannot resolve symbol 'junit'"

"Cannot resolve symbol 'mockito'"

In Vogel's tutorial, a lot more dependencies are required, and I want the bare minimum.

Also, using Vogel's tutorial, I get:

Warning:Conflict with dependency 'com.android.support:support-annotations'. Resolved versions for app (22.2.1) and test app (22.2.0) differ.

So my question is: How can I get the dependencies from Android's page to work?

The support-annotations issue is a known one. You can find the info in their issue tracker. To workaround it, in the main (app, not module) build.gradle file, section allprojects add 

configurations.all {
    resolutionStrategy.force 'com.android.support:support-annotations:22.2.0'
}

(see answer #11 in the same link).

About the extra dependencies, you are going to need dexmaker and dexmaker-mockito for using mockito for your tests in devices/emulator, as they run on a Dalvik VM that expects .dex files, while mockito generates .class files. Unit testing as in the newest unit testing added to Android Studio, runs in your local JVM so it should probably run without dexmaker, but I cannot confirm this as of yet.
