Robolectric Unit Test fails with NoClassDefFoundError when the app depends on AppsFlyerLib

Question

My app has following appsflyer dependencies:

'com.appsflyer:af-android-sdk:4.8.15' 'com.android.installreferrer:installreferrer:1.0'

And, I have tried running Robolectric unit test with appsflyer dependency added, but my test did not start but just throws an error, which is below(I can run the test and test succeeds if I remove the appsflyer dependency.)
