Hi! I am part of the AVA team. For 0.15, we've added awesome features such as better test filename conventions (we run `__tests__` directories automatically), being able to submit tests that should fail, test macros, and experimental support for limited concurrency.
Hope you like it! Let us know in the issues or Gitter[1] if you have any problems.
