Add More Tests To Core Modules

[opticyclic]

#53 is blocked because the examples projects are apparently being used as tests:

I'm not sure this is a good idea for all of the samples.

They test important functionality. I think we should do this only after we've added more tests to the core modules.

@roastario please list the functionality that needs moving to tests and whether it needs to be unit or integration (using the DriverDSL for instance) so we can unblock it.

Thanks This will likely have to wait until the next release.
