Unit Test Ice Breakers

So you’re looking at this pre-existing code. You aren’t sure what to do with it, but you need to get some unit tests going. What do you do when you get stuck.

• Start by testing you can instantiating the class.
• Test that you can call the function at all.
• Pick the easiest bit of functionality.
• Write the name and assertion first.
• Write the function call as you would like it to appear.
• Refactor the existing tests.
• Pick the most interesting bit of functionality.
• Switch partners.
• Read the code for obvious flaws.
• Rerun the AT

Again, this is part of the work being done by myself and Jeff Langr.
