Makes me wonder if there should be an open source test suite for numerical routines, i.e. just a big table (in JSON or something) of inputs, transformations and expected outputs, so new projects could get easily started with a fairly robust (if not a bit generic) test suite they could filter to suite their needs as they grow the feature set.
