Machinist and Rails controller tests

Machinist, my test-data generation plugin for Rails, has just gained some features that make it useful for controller tests. You can now do things like:

test "should create post" do
  assert_difference('Post.count') do
    post :create, :post => Post.plan
  end
  assert_redirected_to post_path(assigns(:post))
end

You an also call plan on ActiveRecord associations, making it easy to test nested controllers:

test "should create comment" do
  post = Post.make
  assert_difference('Comment.count') do
    post :create, :post_id => post.id, :comment => post.comments.plan
  end
  assert_redirected_to post_comment_path(post, assigns(:comment))
end

1. Leave a
   comment*

   Use Markdown for formatting.

2. Your name*
3. Your email*

   I’ll keep your email address private.

4. Your web site
