Models Named Test* cause test failures
Reported by Chris | January 17th, 2009 @ 06:22 PM | in 2.x
We do A/B tests and multivariate testing in my rails app and so we have some models named Test*
This is causing some unfortunate testing errors:
$ rails -v Rails 2.1.1
$ rails foo $ cd foo $ ./script/generate model test_something $ rake db:migrate $ rake test
1) Error:
test_somethings(ActionController::TestCase): ArgumentError: wrong number of arguments (0 for 1)

This is a gotcha with the fixture loading; if you remove test_somethings.yml from fixtures/ the test will pass.
The conflict comes from the accessor method that AR generates; it would be test_somethings(:fixture_name) for this case. Unfortunately, then Test::Unit tries to run that function...

- State changed from “new” to “wontfix”
This is an inherent limitation with test/unit. The fixture accessors are treated as test methods.
The only option short of renaming all those models is to not use the fixtures as mentioned by matt.
