rspec users - Mar 2008 - Has anyone seen this strange mock behaviour?

I''ve got this example ''group'':

  before(:all) do
    @mock_user = mock_model(User)
    @mock_email_field = mock_model(EmailField, :user => @mock_user)
    @mock_email_field.stub!(:user).and_return(@mock_user)
    EmailField.stub!(:find_by_value).and_return(@mock_email_field)
  end

  it "should find existing user by email when asked for
group_user_from_attributes" do
    # @mock_email_field.stub!(:user).and_return(@mock_user)
    EmailField.should_receive(:find_by_value).with("joe at
blow.com").and_return(@mock_email_field)
    User.group_user_from_attributes(:email=>"joe at blow.com")
  end


This fails with a message:
should find existing user by email when asked for group_user_from_attributes
Mock ''EmailField_1001'' received unexpected message :user with
(no args)

Note that I defined the @mock_email_field to stub the user method.

If I uncomment the restubbing of the @mock_email_field in the example, it works.

It certainly seems that @mock_email_field points to the same object in
either case.

I''ve also tried using stub! in the before block instead or or in
addition to hash stub in mock_model, but unless I stub it in the
example no joy.

A couple of us have been scratching our heads over this and I thought
I''d throw it out to the wider RSpec community.

before(:all) will only be executed once - before all of your examples.
Why are you using before(:all)?

It''s highly recommended you don''t use before(:all) - and
definitely
not with mocks. All sort of sideeffects might happen.

Because I had a brain f*rt.

Actually I just caught this myself before checking back with the list.

Thanks!
