The RSpec 2 generator matchers are used to match on file content that are the result of running the generator under test. 
These matchers can be used to test if the resulting file contains content/ruby code as expected (or specified).  

* have_class name, &block
* have_module name, &block
* have_method name, &block, type:Symbol (:class)
* include_module name
* inherit_from name, &block
* have_call name, [args]
* have_block name, [options] 

h3. Example use of matchers

<pre>
g.should generate_model name do |content|
  content.should have_class name do |klass_content|
    klass_content.should include_module 'Canable::Ables'
  end
end
</pre>

h4. have_class

<pre>have_class MyClass do |class_content|
  class_content.should ...
end
</pre>

h4. have_module

<pre>have_module MyModule do |module_content|
  module_content.should ...
end
</pre>

h4. have_method

<pre>have_method :song do |song|
  song.should ...
end
</pre>

h4. have_method

<pre>have_method :song do |song|
  song.should ...
end
</pre>

h4. include_module

<pre>include_module 'UserRoles'</pre>

h4. inherit_from

<pre>inherit_from 'ActiveRecord::Base' do |klass|
  klass.should ...
end
</pre>

h4. have_call

<pre>have_call 'move', :args => ':north'</pre>

Note: Currently not tested. Any issues?

h4. have_block

<pre>have_block 'move', :args => ':north', :block_args => 'place'</pre>
