Unit tests for Schedulers #27
Description
Schedulers are currently uncovered. It would be great to have a good coverage on those, too, following a BDD structure similar to how we've done the tests for sources and sinks.
The first part of this task involves a little bit of Test Architecture to make sure tests will look elegant, be efficient and easy to write (take how sources and sinks have been covered as an example), by actually creating a first few tests, as well.
