# 09 - Testing Detection Rules: Unit Testing for Security Logic

Unit testing for detection rules: test framework, synthetic log generation, red team validation and coverage metrics.

## What you'll learn

- Detection rules are code: they need tests like any other code
- sigma-test allows co-located tests with the rule in native YAML format
- pytest offers flexibility for advanced tests: stress testing, coverage, parameterization
- Automatically generated synthetic logs cover more cases than manual events
- CI/CD gate prevents deployment of faulty rules to production
