Testing Procedures

Invoke with /tzurot-testing for test-related procedures.

Testing patterns are in .claude/rules/02-code-standards.md - they apply automatically.

Running Tests

# Run all tests
pnpm test

# Run specific service
pnpm --filter @tzurot/ai-worker test

# Run specific file
pnpm test -- MyService.test.ts

# Run with coverage
pnpm test:coverage

# Run only changed packages
pnpm focus:test

Coverage Audit Procedure

# Run unified audit (CI does this automatically)
pnpm ops test:audit

# Filter by category
pnpm ops test:audit --category=services
pnpm ops test:audit --category=contracts

# Update baseline (after closing gaps)
pnpm ops test:audit --update

# Strict mode (fails on ANY gap)
pnpm ops test:audit --strict

Unified Baseline: test-coverage-baseline.json (project root)

Test File Types

| Type | Pattern | Location | Infrastructure | | ----------- | ------------------ | --------------------- | -------------- | | Unit | *.test.ts | Next to source | Fully mocked | | Integration | *.int.test.ts | Next to source | PGLite | | Schema | *.schema.test.ts | common-types/types/ | Zod only |

Debugging Test Failures

1. Run Specific Test

pnpm test -- MyService.test.ts --reporter=verbose

2. Check for Fake Timer Issues

// ❌ WRONG - Promise rejection warning
const promise = asyncFunction();
await vi.runAllTimersAsync(); // Rejection happens here!
await expect(promise).rejects.toThrow(); // Too late

// ✅ CORRECT - Attach handler BEFORE advancing
const promise = asyncFunction();
const assertion = expect(promise).rejects.toThrow('Error');
await vi.runAllTimersAsync();
await assertion;

3. Reset Mock State

beforeEach(() => {
  vi.clearAllMocks(); // Clear call history, keep impl
});
afterEach(() => {
  vi.restoreAllMocks(); // Restore originals (spies only)
});

Creating Mock Factories

// Use async factory for vi.mock hoisting
vi.mock('./MyService.js', async () => {
  const { mockMyService } = await import('../test/mocks/MyService.mock.js');
  return mockMyService;
});

// Import accessors after vi.mock
import { getMyServiceMock } from '../test/mocks/index.js';

it('should call service', () => {
  expect(getMyServiceMock().someMethod).toHaveBeenCalled();
});

Integration Tests with PGLite

describe('UserService', () => {
  let pglite: PGlite;
  let prisma: PrismaClient;

  beforeAll(async () => {
    pglite = new PGlite({ extensions: { vector } });
    await pglite.exec(loadPGliteSchema());
    prisma = new PrismaClient({ adapter: new PrismaPGlite(pglite) });
  });

  it('should create user', async () => {
    const service = new UserService(prisma);
    const userId = await service.getOrCreateUser('123', 'testuser');
    expect(userId).toBeDefined();
  });
});

⚠️ ALWAYS use loadPGliteSchema() - NEVER create tables manually!

Integration Test Triggers

Integration tests (*.int.test.ts) run separately from unit tests and are not included in pnpm test or pre-push hooks.

Always run pnpm test:int after:

| Change | Why | | -------------------------------- | --------------------------------------------------------------------- | | Add/remove slash command options | CommandHandler.int.test.ts snapshots capture full command structure | | Add/remove subcommands | Same snapshot tests | | Restructure command directories | getCommandFiles() discovery changes affect command loading | | Change component prefix routing | Integration tests verify button/select menu routing |

Update snapshots with: pnpm vitest run --config vitest.int.config.ts <file> --update

Definition of Done

• [ ] New service files have .int.test.ts
• [ ] New API schemas have .schema.test.ts
• [ ] Coverage doesn't drop (Codecov enforces 80%)
• [ ] Run pnpm ops test:audit to verify no new gaps
