Subject [18/55] [abbrv] beam git commit: Fix Queries tests
Date Wed, 23 Aug 2017 17:09:26 GMT
Fix Queries tests

Workaround for issue #22 + extra cleaning

Replace junit asserts by hamcrest asserts
Set numEvents in test to the minimum number that makes the tests pass
issue #15

comments, improve asserts (hamcrest), reformat

For now make generate monothreaded
