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().

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.
