Creating automated tests
In an ideal world, every system would have a large amount of testing, both automated and manual, that's done by developers and QA. Some ways to test your game is working correctly involve doing the following:
- Using types to prevent programmer errors
- Playing the game yourself
- Performing automated unit tests
- Performing automated integration tests
So far, we've only used the first two, which is an unfortunately common approach in real-world code. This can be suitable for personal or hobby projects but it isn't robust enough for production applications, particularly those written by a team.
Almost any application can benefit from automated, programmer-written unit tests and as a program becomes even larger, it begins to benefit from integration tests as well. There's not a consistent definition of the differences between these two types of tests as you tend to know them when you see them, but fortunately, we can...
