Mocha with blocks

The popular ruby mocking library, mocha, has a handy feature for testing incovations. The with method can take a block. This is useful for assert params that you are calling the object with.

  # common usage

  # use a block to verify parameters
  User.expects(:save).with do |user|
    assert_equal 'tyler', user.first_name
    assert_equal 'mercier', user.last_name
    assert_equal 'active', user.status
