Hmm, not sure why all the other commits we included in this PR, let me try to fix that...

[manuelmeurer]

I changed the other tests that were using wait: 0.01 to use wait: false, otherwise it would be confusing why they are using a tiny delay when wait: false is also possible.

[manuelmeurer]

Actually, we don't need the check for duration in the test I added, since the timeout param would raise an error if there was any wait... shall we remove it?

This is looking good. As far as the tests go, it would be nice to have a few of the specs still implement numerical values as a check to ensure there were no regressions or breaking change with the implementation there.

Basically a check to ensure that non zero and above waits still perform as intended (negatives seem to be accounted for in the tests currently)

[manuelmeurer]

Sure, makes sense, I changed four occurrences back to wait: 0.01.
