# Fixture Architecture Playbook
|
|
|
|
- Build helpers as pure functions first, then expose them via Playwright `extend` or Cypress commands so logic stays testable in isolation.
|
|
- Compose capabilities with `mergeTests` (Playwright) or layered Cypress commands instead of inheritance; each fixture should solve one concern (auth, api, logs, network).
|
|
- Keep HTTP helpers framework agnostic—accept all required params explicitly and return results so unit tests and runtime fixtures can share them.
|
|
- Export fixtures through package subpaths (`"./api-request"`, `"./api-request/fixtures"`) to make reuse trivial across suites and projects.
|
|
- Treat fixture files as infrastructure: document dependencies, enforce deterministic timeouts, and ban hidden retries that mask flakiness.
