rspec users - Feb 2008 - Shared Examples + “initialized constant” warnings

Hi List,
I''m using rspec''s shared example groups in a rails project
(rails
2.02, rspec(on_rails) 1.1.3) and I''m getting lots of errors of the  
following kind when(before) running the specs:

(RAILS_ROOT)/vendor/plugins/rspec/lib/spec/extensions/main.rb:78:  
warning: already initialized constant ContentExamples
(RAILS_ROOT)/vendor/plugins/rspec/lib/spec/extensions/main.rb:78:  
warning: already initialized constant EditViewExamples

The shared example groups are defined in files like spec/shared/ 
foo_examples.rb
and declared as
share_as :FooExamples do?end
(and then included in other example groups with "include FooExamples")
They''re loaded in spec_helper.rb with the following:
Dir.glob(File.join(File.dirname(__FILE__), ''shared'',
''*.rb'')).each do |
shared_example|
   require shared_example
end


I''m guessing that''s what needs to change. Has anyone else seen
these
warnings? I find them quite annoying and would like to get rid of  
them. Any pointers would be much appreciated.
Thanks,
Gerrit

Hey Gerritt.

The likely culprit is in ExampleGroupRunner, which uses the load
command (not require) and therefore reloads anything that might be in
the spec path. That is necessary to support drb, and unlikely to
change, so it is up to you to ensure that shared example groups don''t
get reloaded. How you do that depends on how you are running your
specs and what other config changes you''ve made.

So ... how are you running your specs? Have you made any additional
config changes in terms of what files get loaded?

No changes in terms of loaded files. I''m normally running them via  
autotest, but invoking "script/spec spec/**/*_spec.rb" directly gives
the same warnings (which is what I find weird, considering the shared  
example groups don''t live in *_spec.rb files.

Here''s my spec.opts:
--colour
--format
progress
--format
profile:doc/spec/slowest_examples
--format
html:doc/spec/report.html
--loadby
mtime
--reverse

Thanks for you help,
Gerrit
