# Mock Data Fixtures Deterministic mock data for browser (Playwright) tests. Each fixture exports typed objects that conform to generated types from `packages/ingest-types` or Zod schemas in `src/schemas/`. ## Usage with `page.route()` > **Note:** `comfyPageFixture` navigates to the app during `setup()`, > before the test body runs. Routes must be registered before navigation > to intercept initial page-load requests. Set up routes in a custom > fixture or `test.beforeEach` that runs before `comfyPage.setup()`. ```ts import { createMockNodeDefinitions } from '../fixtures/data/nodeDefinitions' import { mockSystemStats } from '../fixtures/data/systemStats' // Extend the base set with test-specific nodes const nodeDefs = createMockNodeDefinitions({ MyCustomNode: { /* ... */ } }) await page.route('**/api/object_info', (route) => route.fulfill({ json: nodeDefs }) ) await page.route('**/api/system_stats', (route) => route.fulfill({ json: mockSystemStats }) ) ``` ## Adding new fixtures 1. Locate the generated type in `packages/ingest-types` or Zod schema in `src/schemas/` for the endpoint you need. 2. Create a new `.ts` file here that imports and satisfies the corresponding TypeScript type. 3. Keep values realistic but stable — avoid dates, random IDs, or values that would cause test flakiness.
