One pillar of my high code-coverage is this little plugin, which allows you to simply state that a controller or a action should behave RESTfully.
So far it is experimental, meaning it works on my machine 🙂
Any testers and contributes highly welcome.
Install instruction and usage.
Example
describe UsersController do before :each do login_as :quentin #if your controllers need login @item = @user = stub_model(User)#or anything else that has a to_param method end behave_like_resource end
