Overview

This stub overrides OpenURI’s open method to allow programs that use OpenURI to be easily tested.

Usage

 require 'rc_rest/uri_stub'

 class TestMyClass < Test::Unit::TestCase

   def setup
     URI::HTTP.responses = []
     URI::HTTP.uris = []

     @obj = MyClass.new
   end

   def test_my_method
     URI::HTTP.responses << 'some text open would ordinarily return'

     result = @obj.my_method

     assert_equal :something_meaninfgul, result

     assert_equal true, URI::HTTP.responses.empty?
     assert_equal 1, URI::HTTP.uris.length
     assert_equal 'http://example.com/path', URI::HTTP.uris.first
   end

end
