Join Bill Weinman for an in-depth discussion in this video Prototyping in a testbed, part of iOS App Development: Building Data-Driven Apps with SQLite.
- Sometimes in the course of your work as a programmer,…you'll need to try a snippet of code or test out an idea…or even write a simple TestSuite 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 testbed to test your idea in.…This is different than unit tests,…which are designed to validate existing code.…This testbed is for experimenting and working out ideas.…Here I have open an Xcode, a working copy of testbed-done…from chapter 1 of the exercise files.…
This is a very simple app.…It's useful for testing things on the simulator…or on a device.…Notice that it has a UITextView…and a simple method for showing messages…on the textview, you can see this message method down here,…and here it is in use inside this range base for loop.…So when I build this and run it,…see it's running here in the simulator,…and it has, this is line 1, 2, 3 through 10,…it has the testbed 1.1, and you'll notice…here in viewDidLoad,…it prints out the version and then it calls test 1…
