I submitted a ticket for Cucumber, and I hope that it gets accepted:
I encountered a problem when I was using cucumber today. I changed a small detail in one of my Rails controllers and when I ran the features many of them turned red! Disaster! So I scrolled back up, found one that was failing and copy and pasted the file:line syntax into the cucumber command and made them all work! What I didn't like about this process was that I had to scroll back up through a mixed mountain of red and green features. I only wanted to know which of my features were failing. Trudging through this mess, I thought "If only cucumber showed me the failing features in the summary, along with all the other useful information it displays there" and then I remembered "Cucumber is an open-source project, I could fork it and add it during my spare time!". So I did. My commit that adds this functionality is added here: http://github.com/radar/cucumber... for all to gaze upon, criticise and ideally improve upon. At the moment it does everything but exceptions that are raised during Scenarios, something I intend to look on later this evening or perhaps one of you lovely people could do that. I'd really love to see this merged into the core since I believe (along with my coworkers and friends) this is "extremely fucking useful". Thanks for reading!
And now the ticket's been accepted and applied! Thanks to Aslak for this!
