Hi, Just published my blog post on ParametrizedTests that is a proposal that addresses the question we have been discussing in this thread. http://car.mines-douai.fr/2013/10/parametrized-tests/
I believe it can be easily integrated into Pharo's SUnit. Noury On 25 sept. 2013, at 12:38, Frank Shearar wrote: > Hi Noury, > > At the moment it's hard-coded to 100 data points.
