One of my model code methods is throwing an error when run using script/console in test but not in development. I’d be grateful if someone can tell me the differences between the two, beyond the database that they connect to. Thanks. ---

I think all the differences are the differences between the settings in test.rb and development.rb in config/environment/ plus those in database.yml. 2009/5/9 Lee [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

A stack trace for the error will help out quite a bit. The most notable difference between the two environments is that the test environment has cache\_classes = true, which triggers preloading of the application classes on startup. But again, without a stack trace, it’s hard to tell. –Matt J.
