Strange rake test issue on rails 2.4 to 3.0.20 upgrade

Hi all !

I’m currently upgrading a huge app from Rails 2.4 to 3.0.20 and I’m running on Ruby 1.9.3-p448
The switch have been done with success except for the tests.

I’ve a strange issue and I’m not able to fix it :frowning:

When I’m running my tests via ‘rake test’ all the tests fail with a ‘no route matches error’ … But if I’m trying to run a specific one like rake test:functionals TEST=test/functional/users_controller_test.rb
everything work well !
I checked multiple examples on the web, checked my routes etc … For the moment nothing worked :frowning:

It’s really strange and really desapointing because that’s the last step I need to fix to finish the rails upgrade.

Do you have any suggestion or idea to fix it ?

Thanks all in advance !
