Hello, I am following along with your article https://proandroiddev.com/kotlin-clean-code-for-android-part-1-3d01703ebea8. I tried to run the unit tests in your repo, and they are failing because of LeakCanary:

Any ideas? Thanks

Hello Igor, Junit and LeakCanary do not work together, for the time being, the ugly hack is to introduce the build variant called 'unitTest'. Please change the build variant to unitTest and run the tests. Readme.md already reflects the same.

"3. When running the unit test cases choose the debug variant unitTest, it will not work with debug or release variants"

Thanks.
