## Summary Unifies test mocking tooling across Jest and Storybook, replaces handcrafted mock data with auto-generated server-fetched data, and restructures the mock data generation script for maintainability. ### Mock data generation - Split `generate-mock-data.ts` into three focused modules under `scripts/mock-data/`: - `utils.ts` — shared authentication, GraphQL client, and file writer - `generate-metadata.ts` — fetches object metadata from `/metadata` - `generate-record-data.ts` — fetches record data from `/graphql` using metadata-driven dynamic queries - The orchestrator (`generate-mock-data.ts`) authenticates once and passes the token to both generators - Company records are now fetched from the actual server (limited to 10 records) instead of being handcrafted - Generated files are organized under `generated/metadata/objects/` and `generated/data/companies/` ### Unified test utilities - Consolidated Jest and MSW mocking into shared utilities that compose production code (`prefillRecord`, `getRecordNodeFromRecord`, `getRecordConnectionFromRecords`) with mock metadata - Renamed `generateEmptyJestRecordNode` → `generateMockRecordNode` and moved to `testing/utils/` - Extracted `generateMockRecordConnection` into its own file - Removed `sanitizeInputForPrefill` workaround (no longer needed with correctly shaped generated data)

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
