After adding Multidex, tests through the console stopped running. If run from a package or class, then everything works. And through the console there. The application itself is going.

Part logcat:

    Don't use MultiDexTestRunner , which is deprecated; use AndroidJUnitRunner instead.

    https://developer.android.com/studio/build/multidex#testing

    If in Russian: Do not use outdated MultiDexTestRunner ; instead use AndroidJUnitRunner

     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    • The same state of affairs remains. I originally used AndroidJUnitRunner . Later in the course of the experiments I tried MultiDexTestRunner - Ivan
    • What - and the error is the same? - woesss
    • By the way, no. There was java.lang.NoClassDefFoundError Updated a question. Does this mean multidex-config.txt is not correct then? - Ivan
