Is there a way to undo Mocha stubbing of any_instance?

Within my controller specs I am stubbing开发者_运维知识库 out valid? for some routing tests, (based on Ryan Bates nifty_scaffold) as follows :-

it "create action should render new template when model is invalid" do
  Company.any_instance.stubs(:valid?).returns(false)
  post :create
  response.should render_template(:new)
end

This is fine when I test the controllers in isolation. I also have the following in my model spec

it "is valid with valid attributes" do
  @company.should be_valid
end

Again this works fine when tested in isolation. The problem comes if I run spec for both models and controllers. The model test always fails as the valid? method has been stubbed out. Is there a way for me to remove the stubbing of any_instance when the controller test is torn down.

I have got around the problem by running the tests in reverse alphabetic sequence to ensure the model tests run before the controllers but I really don't like my tests being sequence dependant.

You need to manually configure RSpec.

Rspec.configure do |config|
  ...

  # == Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr
  # config.mock_with :rspec
end

Also, remember that Rspec provides its own methods to mock an object. Use the RSpec API or you won't be able to benefit from library abstraction. http://rspec.info/documentation/mocks/message_expectations.html

I'm having the same issue but not using Rspec but normal Test::Unit, actually ActionController::TestCase.

The defined expectations are keeping alive among the tests.

Is there any clue how can I reset my expectations between tests?

• Ruby: 1.9.2
• Rails: 3.0.3
• Mocha: 0.9.10

Updated: I have solved this with the unstub Mocha method: http://mocha.rubyforge.org/classes/Mocha/ObjectMethods.html#M000009

Does your spec_helper contain

Spec::Runner.configure do |config|
  config.mock_with :mocha
end

With that rspec should tear down mocks between tests.
