running rails 2.3, I do a rake test:units. No tests only default stuff. I get: You have a nil object when you didn’t expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[] Any ideas? I have no real tests yet. ---

But first look at it try and see why something that is expected to be one of your model objects is acutally nil. Colin ---
