+=== Dummy for testing
+
+A Dummy class is also provided for use with tests. The dummy class will return a response based on the response code given.
+
+You can instantiate an instance of the DummyInteltechSms, passing the initial credit, and optionally the response code
+
+Example ruby code:
+
+    require 'rubygems'
+
+    require 'dummy_inteltech_sms'
+
+    test_sms = '123'
+
+    gateway = DummyInteltechSms.new(1)
+
+    credit = gateway.get_credit.inspect
+
+    puts "You have #{credit} Credit/s left"
+
+    res = gateway.send_sms(test_sms,'Test from Ruby')
+    puts "send_sms to #{res.sms} was successfull."
+
+    credit = gateway.get_credit.inspect
+    puts "You have #{credit} Credit/s left"
+
+    begin
+      # This will return no credit
+      res = gateway.send_sms(test_sms,'Test from Ruby')
+      puts "send_sms to #{res.sms} was successfull."
+    rescue ex => InteltechSms::Error
+      puts "send_sms to #{res.sms} failed. Gateway response #{ex.response.class} with code #{ex.response.response_code}."
+    end
+
+    res2 = gateway.send_multiple_sms([test_sms, test_sms2, landline_sms],'Test from Ruby to multiple numbers')
+
+    gateway.response_code = InteltechSms::UNAUTHORIZED_RESPONSE_CODE
+    # OR
+    gateway = DummyInteltechSms.new(1,InteltechSms::UNAUTHORIZED_RESPONSE_CODE)
+
+    puts "send_multiple_sms (sending to mobiles should work, sending to a landline should fail):"
+    puts res2.collect {|r| "sms to #{r.sms} #{r.success? ? 'was successfull' : "failed (#{r.class} with code #{r.response_code})"}."}.join("\n")
