Test Coverage Gaps - StrategIQ

This document outlines areas that need additional test coverage. Each section should be converted to a GitHub issue for tracking.

🚨 High Priority - Critical Path

Issue: E2E Test for Complete Analysis Flow

Priority: High Effort: Medium

Description: Need end-to-end test that covers the complete workflow:

1. User submits analysis form
2. Background Celery task processes analysis
3. Status updates via HTMX polling
4. Final SWOT results rendered
5. PDF download triggered

Current Coverage: Individual endpoints tested, but not full integration Gap: No test covering Celery worker, real AI agent execution, complete flow

Suggested Tests:

• test_complete_analysis_workflow_e2e() - Mock AI agent, verify full flow
• test_analysis_with_real_celery_worker() - Integration with Celery
• test_multiple_concurrent_analyses() - Session isolation
