MockServer

A quick way of mocking an external web service you want to consume.

Usage

You're writing a feature that needs to connect to an external web service (anything served by HTTP). You wonder how to test that. Your options are to stub methods in Net::HTTP and equivalents, but by doing that you are tying yourself to an implementation detail. The ideal thing to do is to lay out an environment where your code can still run, connect to a web server, send out requests and get responses back. Enter MockServer.

class RSSFeedTest < Test::Unit::TestCase
  extend MockServer::Methods

  mock_server {
    get "/feed.xml" do
      <<-EOS
      <?xml version="1.0"?>
      <rss version="2.0">
        <channel>
          <title>A mock website</title>
          <link>http://example.com/</link>
        </channel>
      </rss>
      EOS
    end
  }

  def test_rss_feed
    # YourAwesomeComponent should connect to http://localhost:4000.
    # (you *are* putting those URLs in an environment-aware config file, right?)

    posts = YourAwesomeComponent.load_posts

    assert_equal "A mock website", post.first.channel.title
  end
end

Yes, things happening inside the mock_server call are just a regular Sinatra application. w00t!

Not available on rubygems.

I tried to bundle install this gem off of ruby-gems in my rails app and it doesn't seem to find it. 🤔
