after applying this lib to my project i still get the error below

Mockito can only mock non-private & non-final classes.
If you're not sure why you're getting this error, please report to the mailing list.



IMPORTANT INFORMATION FOR ANDROID USERS:

The regular Byte Buddy mock makers cannot generate code on an Android VM!
To resolve this, please use the 'mockito-android' dependency for your application:

Here is my custom test runner

It is the Mockito bug.
mockito/mockito#1472

Add the following line after DexOpener#install in your AndroidJUnitRunner.

System.setProperty("org.mockito.android.target", context!!.cacheDir.absolutePath)
