rspec users - Feb 2009 - undefined method `inherit'' for Merb::Test::ExampleGroup

RSpeckers:

I''m trying to install this into a Merb-generated RSpec rig:

   http://code.jeremyevans.net/doc/fixture_dependencies/

It requires inserting their test case into RSpec. This is the documented way to 
do it:

describe ''Post'' do
   inherit FixtureDependencies::SequelTestCase

And that leads to the syntax error in the subject line. (No stack trace is 
available - ask the Merb spec runner why!)

Has anyone seen that one before?

Hi Phlip,

Are you sure it''s inherit and not extend?
Second, I guess the missing trace is cuz you should
put a ''before'' block into the describe.
Took me some time to figure that out last month...

so try this and let us know the results:

describe ''Post'' do
   before do
     extend FixtureDependencies::SequelTestCase
   end
end

ciao, tom

Per the blogs, inherit() got invented to install Test::Unit::TestCase, to get 
its extra goodies. That''s a class, so you can''t extend or
import it!

Were those blog entries since redacted?

Huh? The trace is just missing; test runners should propagate it.

Here''s the relevant bits that don''t work. (I changed the goal
library to the
''assert2'' patched into Test::Unit::Assertions.)

require File.join( File.dirname(__FILE__), ''..'',
"spec_helper" )
require ''test/unit''
require ''assert2''


describe ''Post'' do

   before do
     include Test::Unit::TestCase
      # inherit Test::Unit::TestCase # does not compile
      # include Test::Unit::Assertions # does not import assert{}
   end

   it ''should have fixtures'' do
     posts = posts(:Joan_Crawford_Has_Risen, :Jammin, :Sardonicus, :Lithium)
     posts[0].body.should == ''From the Grave''
     posts[0].tags.should include(tags(:progressive))

  # this line never compiles
     assert{ posts[0].tags.include? tags(:rocksteady) }
   end

end

The rspec-rails plugin sure has me spoiled, huh? I formerly thought 
Test::Unit::Assertions would be automatically available, even without Rails 
around...

I have to bump this one because it looks like it''s on RSpec''s
core feature list,
and I reeally need a fix for it.

Feel free to blame Merb, if they munged the inherit() method somehow!

I''ll blame Merb on the basis that there is no "inherit" in
RSpec.  I''m
guessing it''s some kind of merb extension.

I know I know - time flies!

If it has been superseded, then how do you inject a batch of assertions defined 
in someone else''s class into RSpec?

For example, how does RSpec on Rails import its ActiveSupport::TestCase
assertions?

rspec-rails defines Spec::Rails::Example::RailsExampleGroup that
inherits from ActiveSupport::TestCase.  All other example groups are
subclasses of REG.

What you want to do is something along the lines of:

class SequelExampleGroup < FixtureDependencies::SequelTestCase
  extend Spec::Example::ExampleGroupMethods
  include Spec::Example::ExampleMethods
  # also any other modules that contain merb-specific expectations
  Spec::Example::ExampleGroupFactory.register :sequel, self
end

describe ''Post'', :type => :sequel do
  ...
end

(I don''t know that that''s exactly it, but it should get you
going)

I think that forcing you to inherit from
FixtureDependencies::SequelTestCase is pretty sucky and I''m not sure
why they don''t just have some modules that you could mix in in the
Spec::Runner.configure block.

module MyMethods
  # define matchers
end

Spec::Runner.configure do |c|
  c.include MyMethods
end

That will include the module in every example group, regardless of the
base class.

Tx that was it!
