@buzzr/dfs-engine-test-vectors

Canonical reference fixtures for @buzzr/dfs-engine.

Each vector is a { entry, gameLogsByLegId, expected } triple that has been verified against the engine in this package's own tests. External integrators who wire their own stat providers or settlement pipelines can replay these vectors to prove their setup grades identically to Buzzr's.

Install

npm install --save-dev @buzzr/dfs-engine-test-vectors @buzzr/dfs-engine

Usage

import { describe, expect, test } from 'vitest';
import { createDfsEngine, defineStatProvider } from '@buzzr/dfs-engine';
import { TEST_VECTORS } from '@buzzr/dfs-engine-test-vectors';

describe('my-integration', () => {
  test('grades canonical vectors identically to Buzzr', async () => {
    for (const v of TEST_VECTORS) {
      const provider = defineStatProvider({
        id: 'mine',
        getGameLog: ({ leg }) => v.gameLogsByLegId[leg.legId] ?? [],
      });
      const engine = createDfsEngine({ statProviders: [provider] });
      const result = await engine.settleEntry(v.entry, { statProviderId: 'mine' });
      expect(result.status).toBe(v.expected.status);
    }
  });
});
