MediationTestSuite.launch() 1.3.0 crash

[kmityakov]

Here's the exception I get when I try to launch MediationTestSuite 1.3.0. Have to fallback to 1.2.2 for now.

java.lang.NullPointerException: Attempt to invoke interface method 'boolean java.util.List.add(java.lang.Object)' on a null object reference

I use the following ads related dependencies:
implementation 'com.google.firebase:firebase-ads:18.3.0' (Checked on 19.0.1 as well)
implementation 'com.google.ads.mediation:facebook:5.7.1.1'
implementation 'com.google.ads.mediation:inmobi:9.0.2.0'

Thanks for reporting @kmityakov. This issue has come up internally and it will be fixed in the next release of the test suite. In the meantime I recommend sticking with 1.2.2 for now.

@stowy Thanks for the info. I'd keep this open before the new release comes out if you don't mind.
