设计和Rspec测试集成

Question

I'm trying to run tests with Devise and Rspec and have been unsuccessful thus far - any help would be greatly appreciated.

rake spec:requests --trace

gives me this error

Answer 1

I don't know exactly what is going wrong, but a quick search for LoadError and the "Expected ... to define" pattern brought up a few relevant discussions.

• Expected ... to Define
• Rails 3.1 — 'load_missing_contant': Expected ... to define ... (LoadError)
• Expected x.rb to define X (LoadError)
• Rails: Why does RSpec crash on my overridden Devise controller request spec?

From the first link:

The error message is misleading. Expected foo.rb to define Foo usually just means that something bad happened when loading foo.rb (syntax errors, missing constant etc...). You can usually get a better error message by just typing Foo into script/console

The error is coming directly from Devise, so perhaps there is some naming conflict in your controllers with the devise controllers? I don't use devise so I don't really know much about how it works. Although I doubt that it's the problem, have a look at the file /Users/carl/.rvm/gems/ruby-1.9.2-head/gems/devise-2.1.2/app/controllers/devise_controller.rb and make sure it's not corrupted. You might try to reinstall the gem in rvm.

Answer 2

A friend helped me figure this one out. In my application controller I was overriding Devise with the below code. Commenting this out allowed rake spec:requests to pass successfully.

# ===============================================
  # == Commented this out to make rspec tests work
  # ===============================================
  # Override Devise create session controller
  # Devise::SessionsController.class_eval do
    # def create
    #  resource = warden.authenticate!(auth_options)
    #     set_flash_message(:notice, :signed_in) if is_navigational_format?
    #     sign_in(resource_name, resource)
    #     @sign_in_path = after_sign_in_path_for(resource)
    #  end
    # end

Thank you again for your time and help!
