test-unit-rails 1.0.0 had been released!
test-unit-rails is a Rails adapter for test-unit 2. You can
use full test-unit 2 features, RR integration and Capybara
integration with test-unit-rails.
Rails supports Test::Unit bundled in Ruby 1.8 and MiniTest
but doesn’t support test-unit 2. Rails with test-unit 2
works but is not fully worked.
