Test Design

Purpose

Produce a lean, useful test plan for a change or component — enough coverage to catch the failures that matter, not enough to drown the change under fixture maintenance.

Test types

Unit tests for pure logic and small functions.
Component tests for module-level behavior with realistic dependencies.
Integration tests for database, queue, API, or external boundaries.
Acceptance-style tests for user-visible behavior or contract surfaces.

## Edge and failure cases

## Tests intentionally not included

Rules

Prefer meaningful coverage over coverage theater.
Tests must be runnable by the project's existing tooling.
Include edge cases and failure cases — happy-path-only suites lie about quality.
Avoid brittle tests that assert implementation details without protecting behavior.
If a test type is intentionally skipped, name it in "Tests intentionally not included" and say why.
