    end

    def test_request_with_response
      FakeWeb.register_uri('http://www.google.com/', :response => `curl -is http://www.google.com/`)
      Net::HTTP.start('www.google.com') do |req|
        response = req.get('/')
        if response.code == 200
          assert_equal "OK", response.message
          assert response.body.include?('<title>Google')
        elsif response.code == 302
          # Google redirects foreign sites to ccTLDs.
          assert_equal "Found", response.message
          assert response.body.include?('The document has moved')
        end
      end
    end

    def test_request_with_custom_status
      FakeWeb.register_uri('http://example.com/', :string => "Nothing to be found 'round here",
                                                  :status => ['404', 'Not Found'])
      Net::HTTP.start('example.com') do |req|
        response = req.get('/')
        assert_equal "404", response.code
        assert_equal "Not Found", response.message
        assert_equal "Nothing to be found 'round here", response.body
      end
    end

    def test_open_uri
      FakeWeb.register_uri('http://example.com/', :string => "Hello, World!")

= Description

FakeWeb is a helper for faking web requests. This makes testing easier,
because you can decouple your test environment from live services without
modifying code. It allows for a range of request behaviour, from simple
stubbing of HTTP responses to re-playing complete recorded responses.

In addition to the conceptual advantage of having idempotent request behaviour, 
FakeWeb makes tests run faster than if they were made to remote (or even local)
web servers. It also makes it possible to run tests without a network
connection or in situations where the server is behind a firewall or has
host based access controls.

FakeWeb is tested with
Net::HTTP[http://www.ruby-doc.org/stdlib/libdoc/net/http/rdoc/index.html] and
OpenURI[http://www.ruby-doc.org/stdlib/libdoc/open-uri/rdoc/]. It should work
with any web client library that uses Net::HTTP for its underlying requests
(e.g., Flickr.rb[http://redgreenblu.com/flickr/],
Ruby/Amazon[http://www.caliban.org/ruby/ruby-amazon.shtml],
soap4r[http://dev.ctor.org/soap4r/], etc.)

= Known Issues

* Request bodies are ignored, including PUT and POST parameters. If you
  need different responses for different request bodies, you need to request
  different URLs, and register different responses for each.
