[Rails3] Displaying the full stack trace for test errors?

Rails
1

I’m porting an app from 2.3 to 3.0, have errors in my test suite, and
don’t get enough info to figure out where these occur. See the example
below; that’s all the feedback I get for an exception raised in a
view.

Suggestions on how I revert to the 2.x behaviour?

  1. Error:
    test_should_show_pet(PetsControllerTest):
    ActionView::Template::Error: undefined method `name’ for nil:NilClass

One way to do this is to export the BACKTRACE environment variable in
the shell executing your Rails 3.0 unit or functional tests: e.g.

BACKTRACE=blegga ruby test/unit/my_unit_test.rb

(setting the BACKTRACE environment variable suppresses the Rails
backtrace filter – see also test_help.rb in railties)
