Following our plan, we must implement this as a test to verify that the correct functionality is there. Our test would look something like this:

  double expectedC = TemperatureConverter.fahrenheitToCelsius(f);
  double actualC = celsiusInput.getNumber();
  double delta = Math.abs(expectedC - actualC);
