FeedValidator :: validating RSS and ATOM feeds using Ruby

Publicado por Edgar González 11 Abril 2006 en Rails, Ruby, Software Libre / Abierto, Testing. english • español

As a result of the work in RubyCorner, I decided to develop a mechanism in Ruby to validate RSS and ATOM feeds.

FeedValidator is a Ruby interface to the W3C Feed Validation online service, based on its SOAP 1.2 support.

It helps to find errors in RSS or ATOM feeds.

FeedValidator add a new assertion (assert_valid_feed) which you can use in your functional tests in Rails applications. This assertion implements a cache to improve the performance of the tests and to not abuse of the W3C Feed Validation online service.

Examples

For use FeedValidator just do this:

PLAIN TEXT

RUBY:

require 'feed_validator'
v = W3C::FeedValidator.new()
v.validate_url('http://www.w3.org/QA/news.rss')
puts v.to_s unless v.valid?

In Rails you can use it in your functional tests, just modify your /test/test_helper.rb adding this line:

PLAIN TEXT

RUBY:

require 'feed_validator/assertions'

And now you can use in your functional test, in this way:

PLAIN TEXT

RUBY:

def test_bar_valid_feed
get :bar
assert_valid_feed
end

Or use the class-level method to quickly create validation tests for a bunch of actions at once:

PLAIN TEXT

RUBY:

assert_valid_feed :bar, :foo
