Introducing the Nova Rules Validation and Testing Pipeline

This article explains the Nova Rules Validation and Testing Pipeline, an automated CI/CD and local toolset for validating Nova detection rules. It covers four primary CI stages—syntax validation, metadata validation, linting, and YAML-based rule testing—describes CI vs full LLM testing modes, outlines pipeline architecture optimizations (targeted triggers, fail-fast syntax gate, parallel jobs, and two-tier caching), and provides example rule/test formats and commands to run validation and tests locally.
