rspec users - Apr 2009 - [cucumber] Tests pass, application does not.

This has just cropped up this morning and I have no clue as to what is
causing it.

Here is the error when running the application through the web browser
in development:

 undefined method `method_exists?'' for #<Entity:0x2b7214243bd0>

/usr/lib64/ruby/gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:255:in
`method_missing''
/home/byrnejb/Software/Development/Projects/proforma.git/lib/hll_attr_set_by_names.rb:16:in
`attr_set_by_names''
...

Here is the code:

14  an.each do |f|
15     puts "checking method: #{f}"
16    self.send("#{f}=", "#{param_hash[f]}") if
self.method_exists?("#{f}=")
17  end

But, when I run the cucumber test for the same controller and view this
is what I see:
...
    And they enter the entity legal name "MyUser  LEGAL  NAME"
       #
features/app/models/entities/step_definitions/entity_steps.rb:66
entity_common_name
entity_legal_name
entity_legal_form
checking method: entity_common_name
checking method: entity_legal_name
checking method: entity_legal_form
    And I press "Create"
       # features/support/step_definitions/local_webrat_steps.rb:14
    Then they should see a save error message
       # features/app/step_definitions/crud_response_steps.rb:24

12 scenarios
78 passed steps

I am lost...  Help?

I just did a github search and the only place I found method_exists?
referenced was in mocha.  So my guess is that in test mode, mocha is
being loaded and so it''s passing for you.  Try using respond_to?
instead of method_exists?  I''ve never even heard of method_exists?
until just now.

I put in a print self.methods.sort.to_yaml and, sure enough, when I do 
this through the browser this is what I see:

...
- mark_for_destruction
- marked_for_destruction?
- metaclass
- method
- method_missing
- methods
- new_record?
- nil?
- object_id
...

I put the same check in the controller
  @entity = Entity.new
  print @entity.methods.sort.to_yaml

and it is missing there as well.



No method_exists?, So, where is it going?

Ahh, thanks. That fixed things.  Most disconcerting to have ones tests 
pass and the application die.

Could be completely off track, Pats mention of Mocha reminded me that 
Rails 2.3 tests have lots of ''require mocha'' dotted around the
place:

David raised a ticket on this:

https://rails.lighthouseapp.com/projects/8994/tickets/2240-let-users-decide-what-mock-framework-to-use

Could this be causing some conflict?

Yes - Rails now requires ''mocha'' in ActiveSupport::TestCase if
you
have it on your system. I''ve filed a ticket about this here:
https://rails.lighthouseapp.com/projects/8994/tickets/2240

It''s not just in Rails'' own tests. It''s actually in
ActiveSupport::TestCase, which means that if you have mocha installed,
it''s getting loaded whether you use it or not.

http://github.com/rails/rails/blob/660fc93942697b74a8093d4d5338d1ced25cbe7f/activesupport/lib/active_support/test_case.rb

Generally speaking, this should really not be a problem. But there are
those odd cases where a conflict may arise because both rspec-mocks
and mocha add methods to object to support partial mocking/stubbing on
any object. It happens that they use different method names.  But, for
example, if we wanted to alias :should_receive with :expects in RSpec
to give it more of mocha''s flavor, we''d be definitely be
risking some
unpleasant behaviour.

David
