@mmiklavc The 10k+ line spec file is a working unit test which contains
mock data as well.
Unfortunately, some other unit tests failing in this PR. We already to a
separate ticket for fixing and enriching unit tests.
@justinleet managed to make UI unit tests part of our Travis build. He
opens a PR for that soon.---
