Sometimes in the course of your work as a programmer you need to try a snippet of code or test out an idea or even write a simple test suite for a class or a library that you're writing. For these situations it can be helpful to have a small, simple, flexible base of code to use as a test bed to test your ideas in. Here we have such a test bed, and I call it Testbed, and you'll notice if I run this in the simulator it displays some messages up on a text view here on this iOS Device.
If we look at the code here I have a simple runTest function that puts out messages using this message function, Testbed version and for id in this array I have a little message that says object is with the string for each member of the array and right here we have Testbed Version 1.0, object is Klaatu, barada, nikto, and that's exactly what we have there. So you can see that this is very simple to test code in. Now, you could leave the stimulator alone, and you could use NSLog, and that's okay, and many people do that--and you can certainly do that if you want to--but it's nice to have the log for errors and the stimulator screen is a lot less cluttered, and it's easy to read this way.
So, this Testbed is easy to build and in fact I've already done a lot of the work for you, so let's take a moment out from our busy day and build a little Testbed to experiment and learn with.
