generate-unit-pure-tests

To generate portable unit tests for pure business logic, provide a behavior specification, test harness path, and codebase root to classify rules as pure or stack-coupled, then output importable spec files for framework-independent testing.

Yes, you can use Jest or Vitest to test extracted pure business rules, as the test harness framework is automatically detected to generate portable spec files that remain valid across stack migrations.

The best way to separate portable business logic from framework-embedded behavior is by classifying behavior spec rules as pure, stack-coupled, or borderline, then generating tests only for the smallest importable pure units.

To handle multi-branch guards and state transitions during unit test generation, map behavior spec rules to the smallest extractable pure units, validating computational logic without HTTP, ORM, or DOM dependencies.

Behavior spec rules are excluded from generated unit test files when classified as stack-coupled, ensuring deterministic tiered testing discipline by recording these exclusions as cited_existing references instead of generating wrong-tier tests.
