Subject Re: IgniteConfigVariationsAbstractTest subclasses do not run
Date Wed, 01 May 2019 12:18:36 GMT
Ivan F.,

I think that it is better to enable IgniteConfigVariationsAbstractTest
subclasses first, so no new broken tests will appear. After that we
can fix IgniteConfigVariationsAbstractTest subclasses one by one in
separate ticket(s).
