Increase test coverage

[dominv]

Current test coverage is 73.45%. We need to increase the test coverage above 80 %

There are a couple of places where I don't understand the 0%, for example the freestyle-slick and freestyle-doobie modules.

@peterneyens Initially, I'm going to check that codecov is well configured and then I'll check what's happening with the tests. In some cases there already are tests but they seem not to be correctly configured. I'll take care of it.

I potentially have a guess about the code coverage.

Follow my attempt here: #285

BTW, any concern replacing AsyncWordSpec by just WordSpec?

• Update: no clue where the problem is. Codecov still interprets test classes as standard source code :(
