[rspec-users] Problems using config.extend(Macro)

Happy New Year everyone!!

I''m having a painful upgrade from Rails 2.3.11 to Rails 3.1.3 and one
of
the problems is with the following....

Under Ruby 1.8.7 - Rails 2.3.11 - Rspec 1:

I have model_macros.rb under spec/spec_helpers and it runs beautifully.

Dir[File.expand_path(File.join(File.dirname(__FILE__),
''spec_helpers'',
''**'', ''*.rb''))].each { require f }
config.extend(ModelMacros, :type => :model)

Exactly the same code under Ruby 1.9.2 - Rails 3.1.3 - Rspec 2 gives me ...
uninitialized constant ModelMacros (NameError)

Dir[Rails.root.join("spec/spec_helpers/**/*.rb")].each {|f| require f}
config.extend(ModelMacros, :type => :model)

.... which makes sense as it''s missing the namespace (but how did it
run
under 2.3.11. Is Ruby 1.8.7 more lenient? - I doubt it)

So I added the namespace and I got rid of that error

config.extend(SpecHelpers::ModelMacros, :type => :model)

But sadly the methods that are called from within the model specs are
unable to be found...... Exception encountered: #<NoMethodError: undefined
method `it_should_require_attributes''

This is only solved by including extend SpecHelpers::ModelMacros in the
model spec file. Not what I want.

Is there something I am missing while migrating all my code? Is there some
really basic Ruby thing I have forgotten to do to get this module included?

I also tried config.include(SpecHelpers::ModelMacros, :type => :model) but
to no avail.

Any help would be great, thank you.

That would make sense if Rails was autoloading (implicit) this, but
it''s not - spec_helper.rb is loading it explicitly. I think the
namespace thing is a red herring.

Which suggests that the config is being silently ignored, even though the
loading is working.

That would never have worked under any version because "include"
exposes methods to the example scope, not the group scope:

describe "something" do
  # methods in modules added using extend are available here
  it "does something" do
    # methods in modules added using include are available here
  end
end
> Any help would be great, thank you.
My best guess is that you don''t need the namespace, and you should
leave Rails out of loading this. Try this:

  Dir["spec_helpers/**/*.rb"].each {|f| require f}
  RSpec.configure do |config|
    config.extend(ModelMacros, :type => :model)
  end

That should work to load the file, since RSpec adds"./spec" to the
$LOAD_PATH.

If that doesn''t work, it might be that ":type => :model"
isn''t working correctly, so try "path => /spec\/model/"
instead. Please report back and let us know which, if either, works for you.

HTH,
David

Hey David, thanks for the reply.

Sadly nothing worked and here are my results

With ....
Dir["spec_helpers/**/*.rb"].each {|f| puts "loading ...
#{f}"; require f}

I didn''t find any file to load and got the following error....

/home/anthony/Development/websites/ruby/GMFT/spec/spec_helper.rb:84:in
`block in <top (required)>'': uninitialized constant ModelMacros
(NameError)

With ....
Dir["spec/spec_helpers/**/*.rb"].each {|f| puts "loading ...
#{f}"; require
f}

I found a file to load but require couldn''t find it ....

loading ... spec/spec_helpers/model_macros.rb
/home/anthony/.rvm/gems/ruby-1.9.2-p290 at
gmft313/gems/activesupport-3.1.3/lib/active_support/dependencies.rb:240:in
`require'': no such file to load -- spec/spec_helpers/model_macros.rb
(LoadError)

With ....
Dir[Rails.root.join("spec/spec_helpers/**/*.rb")].each {|f| puts
"loading
... #{f}"; require f}

I found a file to load, apparently it loaded it but then the
ModelMacros#method could not be found....

loading ...
/home/anthony/Development/websites/ruby/GMFT/spec/spec_helpers/model_macros.rb
/home/anthony/Development/websites/ruby/GMFT/spec/model/event_group_spec.rb:27:in
`block in <top (required)>'': undefined method
`it_should_require_attributes'' for #<Class:0xd25d5fc>
(NoMethodError

I also tried with :path in the third example but nada.

I''ve also tried all of the above running rspec 2.7.0 and rspec-rails
2.7.0.
No joy.

It must be something I''m doing wrong. But what?!!!

David,

I set an instance variable @dut  (domain under test) in a before block in
the spec and use it in the macro. I don''t know if this is the best way
but
I''m not an expert Ruby programmer.

before(:each) do
   @event_group = Factory.build(:event_group)
   @dut = @event_group
end

## and an example call in the spec
it_should_require_attributes :name, :created_by

Here are just a few methods from the macro .....

module ModelMacros
  ## dut - Domain Under Test
  ## aut - Attribute Under Test

  def it_should_require_attributes(*attrs)
    attrs.each { |attr| it_should_require_attribute(attr) }
  end

  def it_should_not_require_attributes(*attrs)
    attrs.each { |attr| it_should_not_require_attribute(attr) }
  end

  def it_should_require_attribute(aut)
    it "is not valid with missing #{aut}" do
      @dut.send("#{aut}=", nil)
      @dut.should_not be_valid
      @dut.should have(1).error_on(aut.to_sym)
    end
  end

  def it_should_not_require_attribute(aut)
    it "is valid with missing #{aut}" do
      @dut.send("#{aut}=", nil)
      @dut.should be_valid
    end
  end
end

I hope this helps. I''m really racking my brains but I just
can''t think of
anything.
