Rails::SubTestTask warns on test failure and moves on. Renamed from TestTaskWithoutDescription.

This makes it easier to add your own tests to the default suite:

  task test: 'test:acceptance'

  namespace :test do
    Rails::SubTestTask.new acceptance: 'test:prepare' do |t|
      t.libs << 'test'
      t.pattern = 'test/acceptance/**/*_test.rb'
    end
  end

Now `rake` runs unit, functional, integration, and acceptance tests.

 require 'rake/testtask'
