Module: Matchbox

Included in:
Test::Unit::TestCase
Defined in:
lib/matchbox.rb,
lib/matchbox/version.rb

Overview

Test::Unit assertions for RSpec and Shoulda matchers.

I created this since:

  • I like assertions, not the Shoulda "should" statements.
  • I want to use shoulda-matchers in my Rails project.
  • I'm in love with the simplicity of the contest gem.

These methods are based upon those found in shoulda-context.

With shoulda-matchers, it can be used like so:

class PostTest < Test::Unit::TestCase
  def test_active_record_relations
    post = Post.new
    assert_accepts belong_to(:topic), post
  end
end
