# 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.

---

## Accomplishments

### 1. T3.14: Execution Completion Notifications (4 tests)
**File**: `tests/e2e/tier3/test_t3_14_execution_notifications.py` (374 lines)

Tests real-time notification system for execution lifecycle events.

**Tests Implemented**:
1. `test_execution_success_notification` - Success completion notifications
2. `test_execution_failure_notification` - Failure event notifications
3. `test_execution_timeout_notification` - Timeout event notifications
4. `test_websocket_notification_delivery` - Real-time WebSocket delivery (skipped - infrastructure pending)

**Key Validations**:
- Notification metadata properly stored for execution events
- Success, failure, and timeout states trigger notifications
- Execution tracking for real-time updates
- WebSocket architecture design (to be implemented)

**Priority**: MEDIUM

---

### 2. T3.15: Inquiry Creation Notifications (4 tests)
**File**: `tests/e2e/tier3/test_t3_15_inquiry_notifications.py` (405 lines)

Tests notification system for human-in-the-loop inquiry workflows.

**Tests Implemented**:
1. `test_inquiry_creation_notification` - Inquiry creation event
2. `test_inquiry_response_notification` - Response submission event
3. `test_inquiry_timeout_notification` - Inquiry timeout handling
4. `test_websocket_inquiry_notification_delivery` - Real-time delivery (skipped)

**Key Validations**:
- Inquiry lifecycle events tracked (created, responded, timeout)
- Notification metadata for approval workflows
- Human-in-the-loop notification flow
- Real-time inquiry update architecture (planned)

**Priority**: MEDIUM

---

### 3. T3.17: Container Runner Execution (4 tests)
**File**: `tests/e2e/tier3/test_t3_17_container_runner.py` (472 lines)

Tests Docker-based container runner for isolated action execution.

**Tests Implemented**:
1. `test_container_runner_basic_execution` - Basic Python container execution
2. `test_container_runner_with_parameters` - Parameter injection via stdin
3. `test_container_runner_isolation` - Container isolation validation
4. `test_container_runner_failure_handling` - Failure capture and cleanup

**Key Validations**:
- Container-based action execution (python:3.11-slim image)
- Parameter passing to containers via JSON stdin
- Container isolation (no state leakage between runs)
- Failure handling with proper exit codes
- Container cleanup after execution

**Priority**: MEDIUM

---

### 4. T3.21: Action Log Size Limits (4 tests)

2. `test_stderr_log_capture` - Separate stdout/stderr capture
3. `test_log_line_count_limits` - High line count handling (10k lines)
4. `test_binary_output_handling` - Binary/non-UTF8 output sanitization

**Key Validations**:
- Log size limits enforced (max 10MB)
- Stdout and stderr captured separately
- High line count (10,000+ lines) handled gracefully
- Binary data properly encoded/sanitized
- No crashes from large or unusual output

**Priority**: MEDIUM

## 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.

3. Add performance benchmarks
4. Integrate E2E tests into CI/CD pipeline

### Long-Term
1. Maintain test suite as features evolve
2. Add operational/chaos testing scenarios
3. Expand container runner tests with more images
4. Test suite performance optimization
