Session Summary: Tier 3 Medium Priority E2E Tests

Date: 2026-01-21
Focus: Implementing Tier 3 medium priority test scenarios
Status: ✅ COMPLETE - 4 new scenarios, 16 tests (~1,732 lines)

---

Overview

Continued implementation of Tier 3 E2E tests, focusing on medium priority scenarios for notifications, container execution, and log handling. Multi-tenancy tests were disabled per user request due to concerns about the multi-tenancy model.

Infrastructure Updates

Helper Functions Added

File: tests/helpers/polling.py

Added wait_for_inquiry_count() helper function:

• Polls for expected inquiry count with timeout
• Supports status filtering (pending, responded, expired)
• Supports comparison operators (>=, ==, <=, >, <)
• Consistent with existing polling helper patterns

Pytest Configuration

File: tests/pytest.ini

Added new test markers:

• notifications - Notification system tests
• websocket - WebSocket real-time notification tests
• container - Container runner tests
• logs - Log capture and size limit tests
• limits - Resource and size limit tests

Technical Decisions

1. WebSocket Tests Skipped: Two tests marked as skipped (not failed) since WebSocket client infrastructure is not yet implemented. Tests are written and ready to enable when infrastructure is available.

2. Container Image Choice: Used python:3.11-slim as the default test image for container runner tests - lightweight and fast for testing purposes.

3. Log Limits: Validated 10MB maximum log size based on reasonable production limits. System prevents memory issues from runaway log output.

4. Notification Metadata: Tests validate that notification metadata is properly stored even though WebSocket delivery is not yet fully implemented. This validates the data layer.

All high-priority security and validation tests are complete. Remaining scenarios are mostly medium and low priority edge cases and operational tests.

The E2E test suite now provides comprehensive coverage across:

• ✅ Core automation (Tier 1)
• ✅ Orchestration & data flow (Tier 2)
• 🔄 Advanced features & edge cases (Tier 3 - 62%)
