I’m using Chris Kampmeier’s FakeWeb to set up my tests for searching with John Nunemaker’s Twitter plugin. My first setups, hitting XML, were really easy and went off without a hitch. But when I needed to start loading JSON for search results, I started getting all sorts of errors: Net::HTTPBadResponse, Can’t convert string to hash, even Can’t convert hash to string. After hours of banging my head against the wall, this is what finally worked for me:


%w[@cdwarren @bphogan].each do |keyword|
  FakeWeb.register_uri(:get, "http://search.twitter.com:80/search.json?q=#{keyword}",
  :string => JSON.parse(File.new("#{RAILS_ROOT}/test/files/search/#{keyword}.json").read))
end

I tried loading the file in several different ways, using :response and :file instead of :string, but they weren’t happy with what I was doing either.

Oh, and for the record, this is how I’m loading the XML files. Many thanks to Brian Hogan for getting me going on this part.


%w[cdwarren bphogan].each do |screen_name|
  FakeWeb.register_uri(:get, "http://twitter.com:80/users/show/#{screen_name}.xml",
  :string => REXML::Document.new(File.new("#{RAILS_ROOT}/test/files/profile/#{screen_name}.xml")))
end

Oh, and don’t forget to require 'json' if you’re going to use JSON.parse!
