description: FaasJS unit testing playbook - use test() only, shared mocks setup, and coverage matrix.

Apply this skill when writing, refactoring, or reviewing unit tests in FaasJS projects.

Core rules

  • •Use test() from @faasjs/dev as the default test entry.
  • •Keep test files in __tests__/ and name them *.test.ts.
  • •Prefer precise assertions (statusCode, data, error, headers) over broad truthy checks.
  • •Extract repeated mock/setup logic into shared test helpers.

Guides

See Test-only workflow for:

  • •Standard test(func) usage patterns
  • •HTTP-style assertions via JSONhandler
  • •Non-HTTP assertions via handler

See Shared testing kit for:

  • •Shared mock lifecycle for repeated module mocks
  • •Reusable caller helper to remove repeated request setup
  • •Recommended shared/ directory layout

See Test matrix for:

  • •Minimal behavior coverage checklist
  • •Incremental run strategy for fast feedback
