[LRUG] Defining constants in ActiveSupport::TestCase ?

[James Adam]

I'm surprised you're seeing this, given that functional and unit tests
run in seperate ruby processes using the default Rails rake tasks. You
should be able to verify this is true by looking at the rake output:

$ rake
(in /Users/james/Code/project)
/opt/local/bin/ruby -I"/Users/james/Code/project/lib"
-I"/Users/james/Code/project/test"
"/opt/local/lib/ruby/gems/1.8/gems/rake-0.8.4/lib/rake/rake_test_loader.rb"
"test/unit/my_model.rb" (and then a bunch more files...)
/opt/local/bin/ruby -I"/Users/james/Code/project/lib"
-I"/Users/james/Code/project/test"
"/opt/local/lib/ruby/gems/1.8/gems/rake-0.8.4/lib/rake/rake_test_loader.rb"
"test/functional/my_controller.rb" (and then a bunch more files...)

As you can see, the unit and functional tests are actually being
invoked using independent ruby instances. Does that help you track
anything down, or at least eliminate one possible source of conflicts?
