If you're developing something that you aren't currently capable of testing or keeping 'tidy', should you just give up? If you focus on developing that thing and make the tests work later, it is absolutely possible to push boundaries. There was no testing framework capable of testing my latest JS library so I built my own; but here's the catch: the testing framework for the library is bootstrapped by the library itself, necessitating building a large amount of the functionality before getting CI in place.
