@tenderlove asked about the wisdom of teaching RSpec to new Ruby developers. I have some relevant experience. Here it is, for what it's worth.

Notes on teaching both test/unit and RSpec to new Ruby developers

@tenderlove asked "Is it good to teach RSpec (vs t/u) to people who are totally new to Ruby?" I have experience suggesting that it is a good thing; after a short back and forth, it seemed useful to write it up in detail.

Background

This goes back several years, to when I was the primary Ruby/Rails trainer for Relevance from 2006-2009. I'm guessing that worked out to probably 6-8 classes a year during those years. Since then, RSpec has changed a fair amount (with the addition of expect) and test/unit has changed radically (it has an entirely new implementation, minitest, that avoids some of the inconsistencies that made test/unit a bit confusing during the time I'm writing about here).

I started out as an RSpec skeptic. I've never been afraid of what a lot of people denigrate as "magic" in Ruby libraries … to me, if you take the trouble to understand it, that stuff's just pr

The limitations of test

From Out of the Tar Pit:

The key problem with testing is that a test (of any kind) that uses one particular set of inputs tells you nothing at all about the behaviour of the system or component when it is given a different set of inputs. The huge number of different possible inputs usually rules out the possibility of testing them all, hence the unavoidable concern with testing will always be — have you performed the right tests?. The only certain answer you will ever get to this question is an answer in the negative — when the system breaks.

This is a strong argument for some form of generative, simulation, or property-based testing.
