Supercharge your Tests with Factories
summary
Factories plus Prisma and TypeScript cut test setup down to reusable build/create factory functions that call Prisma client, use a faker (chance) for randomized defaults, and expose a createFactory abstraction to infer required fields. Tests use a truncated resetDB, Jest runInBand, inline snapshots for error assertions, and Cypress tasks that invoke the same factories from the browser tests. Result: fewer brittle fixtures, one-place updates when a required column appears, higher request and E2E coverage used successfully at Echobind and discussed on GitHub.
