Audit Checklist

1. Test Organization

• Tests grouped by feature/domain
• Naming convention consistent
• Test files co-located with source

2. Test Quality

• No flaky tests
• Fast execution (< 100ms each)
• Clear assertion messages
• Proper setup/teardown

3. Coverage Gaps

• Happy path covered
• Error paths tested
• Edge cases addressed
• Security scenarios included

4. Maintenance

• Tests follow DRY
• Shared fixtures extracted
• Page objects used for UI
• Data builders for test data

For Mansoni

Priority test areas:

1. Auth — login, register, logout, RLS
2. Chat — send, receive, reactions, real-time
3. Storage — upload, download, delete
4. E2EE — encryption, key exchange

Improving Test Quality

// BAD: Unclear test
test('works', async () => {
  const result = await send({ a: 1 });
  expect(result).toBeTruthy();
});

// GOOD: Descriptive test
test('sends message to channel successfully', async () => {
  const result = await messageService.send({
    channelId: 'general',
    content: 'Hello world',
    userId: 'user-123',
  });

  expect(result.id).toBeDefined();
  expect(result.channelId).toBe('general');
  expect(result.content).toBe('Hello world');
  expect(result.createdAt).toBeInstanceOf(Date);
});
