TDD Zombies

Not these zombies

When I first used TDD I read James Grenning’s book Test Driven Development for Embedded C. In this book James proposed following a pattern for developing tests to test for zero, then one and then many (ZOM). Recently he has developed this idea further into ZOMBIE testing.

Z – Zero
O – One
M – Many (or More complex)
B – Boundary Behaviors
I – Interface definition
E – Exercise Exceptional behavior
S – Simple Scenarios, Simple Solutions

I’ve found this to be a really helpful pattern to follow when developing tests. To read more about it see James’ recent post TDD Guided by ZOMBIES
