I've created a Rails project for playing around with something, and
I've made a single controller with two actions in it. The tiny app
runs fine, but I decided to try doing a functional test and see what I
got. But 'rake test' fails with a not-very-useful error, and I don't
know where to go to track it down. Google is as confused as I am. 
Here's what I get when I run rake:
Ryans-MacBook:~/dev/play rew$ rake -v test:functionals (in /Users/rew/dev/play) [some stuff deleted for space] ** Invoke db:schema:load (first_time) ** Invoke environment ** Execute db:schema:load ** Execute test:functionals rake aborted! wrong number of arguments (3 for 2) /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:725:in `fu_check_options' /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:725:in `sh' /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:812:in `sh' /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:747:in `ruby' /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake.rb:812:in `ruby' /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake/testtask.rb:117:in `define' [some stuff deleted for space]
Now, if I run the test directly, it seems to work:
Ryans-MacBook:~/dev/play rew$ ruby test/functional/welcome_controller_test.rb Loaded suite test/functional/welcome_controller_test Started . Finished in 0.02188 seconds.
1 tests, 1 assertions, 0 failures, 0 errors
So how can I track down what's gone busted with my 'rake test' stuff? Any pointers?
