Curated, product-agnostic snapshot of the post-story-04 tree: demo content deleted, auth-only reference feature, web-next shell, all gates green. Product-specific docs, ADRs 027-029, PRDs/epics/archive, editor library traces, and product naming are curated out; generic template repairs (coverage provider devDeps, root test:coverage script, live lint fixes, root-only release-please) are kept. See TEMPLATE.md for provenance, curation list, and usage. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016j8z4VHjedXDTjEDNg7qHK

## Filter: license
|
|
|
|
<!-- Result: MIT -->
|
|
|
|
`npm view @testing-library/jest-dom license` returns `MIT`. MIT is on the allowlist.
|
|
|
|
## Filter: types
|
|
|
|
<!-- Result: native -->
|
|
|
|
`@testing-library/jest-dom` ships its own TypeScript declaration files that extend the vitest/jest `expect` matchers. No separate `@types/` package is needed.
|
|
|
|
## Filter: maintenance
|
|
|
|
<!-- Result: active -->
|
|
|
|
Actively maintained by the Testing Library organization. The 6.x line is the current major. Regular releases tracking vitest and jest compatibility.
|
|
|
|
## Filter: boundary-fit
|
|
|

<!-- Result: pass -->

`@testing-library/jest-dom` is a dependency of `@repo/core-testing`, which is the workspace's shared testing infrastructure package. Custom DOM matchers (`toBeInTheDocument`, `toHaveTextContent`, etc.) are set up in `core-testing`'s setup file and available to all feature test suites via the `core-testing` dependency. This is the correct placement.
|
|
|
|
## Filter: shadow-check
|
|
|
|
<!-- Result: pass -->
|
|
|
|
`@testing-library/jest-dom` is the sole custom DOM matcher extension in the workspace. No competing matcher library is present.
|
|
|
|
## Filter: eu-residency
|
|
|
|
<!-- Result: n/a -->
|
|
|
|
`@testing-library/jest-dom` is a test utility library with no network communication. EU residency does not apply.
|
|
|
|
## Filter: cve-scan
|
|
|
|
<!-- Result: clean -->
|
|
|
|
`pnpm audit --audit-level=moderate` reports no advisories against `@testing-library/jest-dom` at the time of this trace.
|
|
|
|
## Filter: named-consumer
|
|
|
|
<!-- Result: pass -->
|
|
|
|
`@repo/core-testing` uses `@testing-library/jest-dom` to set up custom DOM assertion matchers. Feature packages that render React components in tests use these matchers via `core-testing`. Named, non-hypothetical consumer exists today.
|
|
|
|
## Prompt: replaces
|
|
|
|
`@testing-library/jest-dom` extends vitest's `expect` with semantic DOM matchers, replacing brittle assertion patterns like `expect(el.innerHTML).toContain('text')` with `expect(el).toHaveTextContent('text')`.
|
|
|
|
## Prompt: migration-cost-out
|
|
|
|
Low. `@testing-library/jest-dom` is configured in one setup file in `@repo/core-testing`. Removing it requires updating that setup and replacing any DOM-specific matchers in test files with lower-level assertions.
|
|
|
|
## Prompt: alternatives-considered
|
|
|
|
1. **Plain vitest `expect` matchers only** — Viable but produces less readable test assertions for DOM state; `toBeInTheDocument()` is significantly clearer than checking element existence manually.
|
|
2. **`@vitest/ui` accessibility assertions** — Narrower scope; `@testing-library/jest-dom` covers the full semantic DOM assertion surface.
