  Unit Test for the readField function in the ThingSpeak Communication Library for Arduino

  ThingSpeak ( https://www.thingspeak.com ) is a free IoT service for prototyping
  systems that collect, analyze, and react to their environments.
  
  This test use the ArduinoUnit 2.1.0 unit test framework.  Visit https://github.com/mmurdoch/arduinounit to learn more.
