rspec

Invoking "template.expect_render" automatically registers a listener on :after, but does it on the class Spec::Example::ExampleGroup - and unfortunately our viewspecs are of the type Spec::Rails::Example::ViewExampleGroup, which does not inherit from Spec::Example::ExampleGroup.

This means the :after listener never fires, because Spec::Example::ExampleGroup is not running, and the expectation goes unverified.

The following patch works around the problem by registering a listener on the correct type.

klass = Spec::Rails::Example::RenderObserver
klass.module_eval do
  def unregister_verify_after_each
    proc = verify_rendered_proc
    Spec::Example::ExampleGroup.remove_after(:each, &proc)
    Spec::Rails::Example::ViewExampleGroup.remove_after(:each, &proc)
    Spec::Rails::Example::ControllerExampleGroup.remove_after(:each, &proc)
  end

  def register_verify_after_each #:nodoc:
    proc = verify_rendered_proc
    Spec::Example::ExampleGroup.after(:each, &proc)
    Spec::Rails::Example::ViewExampleGroup.after(:each, &proc)
    Spec::Rails::Example::ControllerExampleGroup.after(:each, &proc)
  end
end
