Over the last day or so, I have been playing with RSPEC. I must admit, its NICE.
What makes it even nicer, is using autotest
This is a nice addon that will automatically run your tests or rspecs when you change files and save them in your rails project.
Even nicer, you can coax it to talk to growl and get the tests to notify you onscreen as to progress.
Really wonderful. and not a daffodil in sight.
