{userInput}
+ + // ✅ ALWAYS DO THIS +
{sanitizePlainText(userInput)}
+ ``` + +2. **Never bypass validation** for "convenience": + ```typescript + // ❌ WRONG + if (isAdmin) { + // Skip lock check for admins + await updateSubmission(id, { status: 'approved' }); + } + + // ✅ CORRECT + // Let RLS policies handle authorization + const { error } = await supabase + .from('content_submissions') + .update({ status: 'approved' }) + .eq('id', id); + ``` + +3. **Always check lock state** before actions: + ```typescript + const isLockedByOther = useModerationQueue().isLockedByOther( + item.id, + item.assigned_to, + item.locked_until + ); + + if (isLockedByOther) { + toast.error('Submission is locked by another moderator');

Test Isolation + +Each test should be independent: +- ✅ Clean up test data in `afterEach` or `afterAll` +- ✅ Use unique identifiers for test records +- ❌ Don't rely on data from previous tests + +### 2. Realistic Test Data + +Use realistic data patterns: +- ✅ Valid email formats +- ✅ Appropriate string lengths +- ✅ Realistic timestamps +- ❌ Don't use `test123` everywhere + +### 3. Error Handling + +Test both success and failure cases: +```typescript +// Test success +test('should approve valid submission', async () => { + const { error } = await approveSubmission(validId); + expect(error).toBeNull(); +}); + +// Test failure +test('should reject invalid submission', async () => { + const { error } = await approveSubmission(invalidId); + expect(error).toBeTruthy(); +}); +``` + +### 4. Async Handling + +Always await async operations: +```typescript +// ❌ WRONG +test('test name', () => { + asyncFunction(); // Not awaited + expect(result).toBe(value); // May run before async completes +}); + +// ✅ CORRECT +test('test name', async () => { + await asyncFunction(); + expect(result).toBe(value); +}); +``` + +### 5.
