this is incompatible with Cucumber

[ghost]

Running rails (3.2.6), ruby (1.9.3-p125), cucumber-rails (1.3.0) , not using RSpec

Not installing test-unit-rails (1.0.2) :

• I can run all my tests ( units , functionals) w rake test
• I can run my cucumber integration tests => cucumber --format progress -r features

Trick , using only gem 'test-unit' in the gem file ( to avoid the faulty notify.rb
and adding 2lines in the Cucumber /features/support/env.rb
require 'test/unit/assertions'
World(Test::Unit::Assertions)

However, after installing test-unit-rails (1.0.2) which seems to require and install all dependencies test-unit (2.5.1), test-unit-activesupport (1.0.0), test-unit-capybara (1.0.2), test-unit-notify (0.3.0)
I get an error

Using the default profile...
undefined method prepare' for Test::Unit::AutoRunner:Class (NoMethodError) ..../gems/test-unit-notify-0.3.0/lib/test/unit/notify.rb:14:inmodule:Unit'
..../gems/test-unit-notify-0.3.0/lib/test/unit/notify.rb:13:in <module:Test>' ..../test-unit-notify-0.3.0/lib/test/unit/notify.rb:12:in<top (required)>'
...
obviously Test::Unit::AutoRunner doesn't have the 'prepare' method

Sorry for my late response.

It seems that test-unit-notify uses Ruby bundled Test::Unit instead of test-unit gem.
I want to try it on my environment. Could you show your test/test_helper.rb?
