Download the two source code files of sample code named Temperature.java and TemperatureConverter.java.$$Those two files make a standalone program which converts Celsius to Fahrenheit and Fahrenheit to Celsius.

For this assignment, write a JUnit test case to test two methods in the Temperature class.$$ Test the toCelsius method, and also write a test case to test the toFahrenheit method.$$ You can write both test cases in one class file, which should be a JUnit test file.
