At first I would imagine you just get an UnknownStep error (or similar). That would trigger a conversation w/ a developer who would peruse the step matchers. Perhaps the next step would be a command to print out all the step matcher expressions so it becomes easier to find the expression (or perhaps that this When has no step defined for it yet). Eventually we could make it smarter, but that would be a way down the road. > > Alvin. > > > Cheers, > > David > > > > > >> Cheers, > >> David > >> > >> > >>> Pat > >>> _______________________________________________ > >>> rspec-users mailing list > >>> rspec-users@rubyforge.org > >>> http://rubyforge.org/mailman/listinfo/rspec-users > >>> > >>> > > > > > > ------------------------------ > > > > _______________________________________________ > > rspec-users mailing list > > rspec-users@rubyforge.org > > http://rubyforge.org/mailman/listinfo/rspec-users > > > > End of rspec-users Digest, Vol 16, Issue 43 > > ******************************************* > > > > _______________________________________________ > rspec-users mailing list > rspec-users@rubyforge.org > http://rubyforge.org/mailman/listinfo/rspec-users > _______________________________________________ rspec-users mailing list rspec-users@rubyforge.org http://rubyforge.org/mailman/listinfo/rspec-users
