Sorry for the really newbie question, but trying this patch with cucumber and getting this error:

Can you help? :(

skiz commented Sep 5, 2011

@khelal I haven't tried this patch with cucumber, only selenium based integration specs. Hopefully this will be fixed upstream soon!

khelal commented Sep 5, 2011

@skiz thx for fast reply and I hope so too. in the meantime, did you have to add a require anywhere in rspec to get it to load or was it automatic? i'm assuming (hoping) it must be the same thing with cucumber..

skiz commented Sep 5, 2011

@khelal, I added it to spec/support which is automatically loaded when using rspec.

khelal commented Sep 5, 2011

@skiz: cool. just had a thought though. cucumber uses rspec right? so if i put it in rspec, it should also work for cucumber no? again, sorry if these are really stupid questions. that's what happens when a non-developer tries to fix something :(
