+## Known Integration Test Issues and Solutions
+
+This section documents common test issues encountered in integration tests, their root causes, and solutions. These patterns recur frequently.
+
+### 1. Vitest globalSetup Runs in Separate Node.js Context
+
+**Problem:** Vitest's `globalSetup` runs in a completely separate Node.js context from test files. This means:
+
+- Singletons created in globalSetup are NOT the same instances as those in test files
+- `global`, `globalThis`, and `process` are all isolated between contexts
+- `vi.spyOn()` on module exports doesn't work cross-context
+- Dependency injection via setter methods fails across contexts
+
+**Affected Tests:** Any test trying to inject mocks into BullMQ worker services (e.g., AI failure tests, DB failure tests)
+
+**Solution Options:**
+
+1. Mark tests as `.todo()` until an API-based mock injection mechanism is implemented
+2. Create test-only API endpoints that allow setting mock behaviors via HTTP
+3. Use file-based or Redis-based mock flags that services check at runtime
+
+**Example of affected code pattern:**
+
+```typescript
+// This DOES NOT work - different module instances
+const { flyerProcessingService } = await import('../../services/workers.server');
+flyerProcessingService._getAiProcessor()._setExtractAndValidateData(mockFn);
+// The worker uses a different flyerProcessingService instance!
+```
+
+### 2. BullMQ Cleanup Queue Deleting Files Before Test Verification
+
+**Problem:** The cleanup worker runs in the globalSetup context and processes cleanup jobs even when tests spy on `cleanupQueue.add()`. The spy intercepts calls in the test context, but jobs already queued run in the worker's context.
+
+**Affected Tests:** EXIF/PNG metadata stripping tests that need to verify file contents before deletion
+
+**Solution:** Drain and pause the cleanup queue before the test:
+
+```typescript
+const { cleanupQueue } = await import('../../services/queues.server');
+await cleanupQueue.drain(); // Remove existing jobs
+await cleanupQueue.pause(); // Prevent new jobs from processing
+// ... run test ...
+await cleanupQueue.resume(); // Restore normal operation
+```
+
+### 3. Cache Invalidation After Direct Database Inserts
+
+**Problem:** Tests that insert data directly via SQL (bypassing the service layer) don't trigger cache invalidation. Subsequent API calls return stale cached data.
+
+**Affected Tests:** Any test using `pool.query()` to insert flyers, stores, or other cached entities
+
+**Solution:** Manually invalidate the cache after direct inserts:
+
+```typescript
+await pool.query('INSERT INTO flyers ...');
+await cacheService.invalidateFlyers(); // Clear stale cache
+```
+
+### 4. Unique Filenames Required for Test Isolation
+
+**Problem:** Multer generates predictable filenames in test environments, causing race conditions when multiple tests upload files concurrently or in sequence.
+
+**Affected Tests:** Flyer processing tests, file upload tests
+
+**Solution:** Always use unique filenames with timestamps:
+
+```typescript
+// In multer.middleware.ts
+const uniqueSuffix = `${Date.now()}-${Math.round(Math.random() * 1e9)}`;
+cb(null, `${file.fieldname}-${uniqueSuffix}-${sanitizedOriginalName}`);
+```
+
+### 5. Response Format Mismatches
+
+**Problem:** API response formats may change, causing tests to fail when expecting old formats.
+
+**Common Issues:**
+
+- `response.body.data.jobId` vs `response.body.data.job.id`
+- Nested objects vs flat response structures
+- Type coercion (string vs number for IDs)
+
+**Solution:** Always log response bodies during debugging and update test assertions to match actual API contracts.
+
+### 6. External Service Availability
+
+**Problem:** Tests depending on external services (PM2, Redis health checks) fail when those services aren't available in the test environment.
+
+**Solution:** Use try/catch with graceful degradation or mock the external service checks.
+

+| podman              | Container management                     |
+| filesystem          | File system access                       |

+| postgres            | Direct database queries (localhost:5432) |
+| playwright          | Browser automation and testing           |
+| redis               | Redis cache inspection (localhost:6379)  |
+
+**Note:** MCP servers are currently only available in **Claude CLI**. Due to a bug in Claude VS Code extension, MCP servers do not work there yet.
