Agent Skills: harper-testing

This skill should be used when adding, repairing, or designing tests for a Harper (HarperDB/Fabric) component app — Vitest unit tests for pure functions and Resource methods, local Harper integration tests that boot/symlink/seed/assert real endpoints, Playwright e2e tests against REST/GraphQL routes, and schema/verify-script coupling. Use it when a Harper app needs its first test suite, endpoint coverage, seed isolation, or a local smoke/verify path. Pairs with harper-build-and-deploy, harper-schema-graphql, and e2e-coverage-gaps.
