title: test-unit gem displays test stat for every rake run
body: <p>I using test-unit gem with a Rails 3.1 project, and I have a small issue. If I start rake tasks, I always see a test result, with zeros.</p>
  
  <p>My Gemfile is:</p>
  
  <pre><code>source :rubygems
  
  gem 'rails', '3.1.2'
  
  gem 'sqlite3'
  gem 'json_pure'
  
  # Gems used only for assets and not required
  # in production environments by default.
  group :assets do
  #  gem 'sass-rails',   '~&gt; 3.1.5.rc.2'
  #  gem 'coffee-rails', '~&gt; 3.1.1'
    gem 'therubyracer'
    gem 'uglifier', '&gt;= 1.0.3'
  end
  
  gem 'jquery-rails'
  
  # Rails i18n
  gem 'rails-i18n', :git =&gt; 'git://github.com/hron84/rails-i18n.git'
  
  # Paginator
  
  gem 'will_paginate'
  
  # To use ActiveModel has_secure_password
  gem 'bcrypt-ruby', '~&gt; 3.0.0'
  
  # Use unicorn as the web server
  gem 'thin'
  
  # Deploy with Capistrano
  gem 'capistrano'
  
  # To use debugger
  # gem 'ruby-debug'
  
  group :development do
    gem 'rails3-generators'
    gem 'nifty-generators'
  end
  
  group :test do
    gem 'rspec'
    gem 'rspec-rails'
    gem 'ci_reporter'
    gem 'factory_girl'
    unless defined? Rubinius
      gem 'rcov'
      gem 'rcov_rails'
      gem 'test-unit'
    end
    gem 'ruby-prof'
    gem 'faker'
  end
  
  # Application-related stuffs
  
  gem 'authlogic'
  
  # Slug helper
  gem 'slug'
  
  # vim: ft=Gemfile
  </code></pre>
  
  <p>Is there a way to avoid it? What I do wrong?</p>
