Mirrors the canonical blog pattern landed earlier on this branch.
Per feature:
- src/__seeds__/dev.ts — lazy buildDev<Entities>() function using the
feature's existing factory for sensible defaults
- src/di/bind-dev-seed.ts — bindDevSeed<Feature>() async function that
rebinds the repo symbol(s) to a populated MockXRepository via
.toConstantValue
- src/di/bind-dev-seed.test.ts — 3+ tests per feature (populates,
reachable by id/slug, idempotent)
- package.json — adds ./di/bind-dev-seed subpath export
Tests + use cases continue to construct mocks directly; the seed never
runs from a *.test.ts path. App boot wiring (USE_DEV_SEED env branch)
follows in a separate commit.
