Property-Based Testing

A different way of testing, putting your tests to work for you.

Audio recorded at Railscamp itself. Still some minor goofs in the slides (a missing | on |x, and a missing .abs on float.abs) that’ve been corrected in the PDF linked above, and one verbal goof where I claimed that Erlang had QuickCheck first. Oops.
