Introduction

This snippet is something I put together to play around with the FestivalsLab API inside a Rails app I was building. I built it with Rails 3 on Ruby 1.9.2 but there's no reason it shouldn't work on older versions of either of those.

This could potentially be used as a bare Ruby library without Rails, but I am using a couple of useful features - Rack's query string parsing and some MIME type handling - that would have to be rewritten to do that. I'm using these features because I don't think that any URI string manipulation should happen outside of a URI library, your philosophy may be different ;)

This code should be considered a work in progress, there are no guarantees that it will work for you, or that it won't wipe your hard drive. But you can see the code, it's all pretty simple.

# A Ruby meta-programming puzzle for polite programmers.

# This puzzle was created by Matt Wynne (@mattwynne) on 2011-04-10 inspired by Jim Weirich's
# talk at the Scottish Ruby Conference 2011.
#
# The challenge is: you have a class Foo which you want to monkey-patch, but politely.

Then /^I should see( only)? the following error messages?( in order)?:$/ do |only, ordered, table|
  # Uses Capybara's `all` CSS selector to find error messages in Rails' default
  # error messages output format
  errors = all(:css, "#errorExplanation li").map { |error| [error.text] }
  errors_expected = table.raw
  errors_actual = only ? errors : (errors & table.raw)
  unless ordered
    # Cucumber cares about the order of tables, If we don't then we need to sort
    # both sets of messages using the same criteria
    errors_actual = errors_actual.sort
