# 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

---

### Issue: AI Agent Testing
**Priority**: High
**Effort**: Large

**Description**:
AI agent (Claude/GPT) has no test coverage. Need tests for:
- SWOT analysis generation
- Tool use (Reddit intelligence)
- Fallback behavior when APIs fail
- Rate limiting handling
- Output validation

**Current Coverage**: None
**Gap**: Core business logic untested

**Suggested Tests**:
- `test_swot_agent_generates_valid_analysis()` - Mock API responses

---

### Issue: HTMX OOB Swap DOM Validation
**Priority**: Medium
**Effort**: Medium

**Description**:
Current tests verify HTML content but don't validate DOM structure for OOB swaps.

**Current Coverage**: Response HTML contains expected strings
**Gap**: No validation that OOB swaps produce correct DOM structure

**Suggested Tests**:
- `test_status_oob_swap_creates_correct_dom()` - Parse HTML, verify structure
- `test_status_timeline_container_has_correct_id()` - Regression test for #status-timeline
- `test_multiple_oob_swaps_append_correctly()` - Sequential swaps

**Tools**: Use BeautifulSoup or lxml to parse HTML and validate structure
