DAO testing: NoClassDefFound error androidx/test/InstrumentationRegistry

Hello everyone I am writing DAO test and I am stuck at this line:

database = Room.inMemoryDatabaseBuilder(
    getContext(),
    SomeDatabase::class.java).build()

I am getting this error:

java.lang.NoClassDefFoundError: androidx/test/InstrumentationRegistry Caused by: java.lang.ClassNotFoundException: androidx.test.InstrumentationRegistry

I have added to my build.gradle :

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

but still no luck. Have anyone experienced similar issues? Thanks in advance.
