Thank you for the clarification. I did misinterpret your statement and have taken your suggestion on board for the enum values. :)

Thank you for your feedback.

One of the reasons why I have not represented the states of the three lights as an enum is because that would not translate well to the actual hardware. In the traffic light hardware there is a high powered 150W bulb for each light. Heach bulb is held in a buld holder. Each bulb holder is switched on by the contacts for the high current side of a mechanical relay. The solenoid of each relay is powered by a low current circuit which is turned on by a transistor. The transisitor is turned on by a very low current supplied to its base pin. So each light needs an on or off state. An Enum does not translate well to the "electronic" interface, but three boolean states do.

I will reword the decription to better describe this.

Is there a .Net unit test equivelent of the Test.Inspect(object) in the JavaScript test framework?

Damn damn damn. I need to learn to read it over and over until it sticks in! Thanks!

B**ger! No I haven't thank you! :)

Awesome, example tests now pass. If only I could read! ;)

Now just need to get the main tests to pass.

Aha. Fairplay. I did get round it in the end. Fantastic kata. Really enjoyed it.
