Make your shoulda tests faster with fast_context 24

I’ve been using Shoulda for a while. And for my current project, I decided to go fixtureless with Shoulda + Factory Girl. All good, except one problem. Slow as fuck tests. So here’s fast_context as a solution for it. fast_context compiles all the ‘should’s within a context into a single test.

For example :

1
2
3
4
5
6
7
8
9
10
11

class UsersControllerTest < ActionController::TestCase
  fast_context "#new" do
    setup do
      @user = Factory(:user)
      get :new
    end

    should_render_template :new
    should_render_with_layout :users
  end
end

This will be compiled into something like :

1
2
3
4
5
6
7
8

class UsersControllerTest < ActionController::TestCase
  test "test: #new should run_fast"
    @user = Factory(:user)
    get :new
    should_render_template :new
    should_render_with_layout :users
  end
end

As your setup method just once per fast_context, the tests run much faster.

To install :



script/plugin install git://github.com/lifo/fast_context.git
