Practical Unit Tests

Andrew Fray  |  Engineer, Spry Fox


Location: Room 304, South Hall

Format: Session
Track: Programming
Vault Recording: Video


Unit testing is common in the wider software world, but it has not taken off in the video game industry. There are many who claim it can't be successfully applied to games. Andrew Fray disagrees, and yet he could not call his first attempt at unit-tested code, a subsystem of a AAA console game, entirely successful. In this talk, Andrew will explain why he believes unit tests are perfectly usable in game development, but that like any technique, they need careful practice and considered application. By dissecting tests from his first project, he will explain the ways in which poor unit tests can affect a project's ability to iterate and grow, while also showing how to avoid these problems in your own code.

Takeaway

Attendees will understand how unit testing can be successfully applied to video game development, and the benefits and drawbacks of this technique. They will see real-life examples of common unit test anti-patterns, understand the problems caused by these anti-patterns, and how to avoid them.

Intended Audience

Programmers who are interested in unit testing or have attempted unit testing (either test-first or test-after), have not had success with it, and want to understand the common pitfalls to avoid.
