Work Summary: E2E Testing Phase 2 - Test Suite Implementation

Date: 2026-01-22
Focus: Implemented E2E integration test suite infrastructure
Status: 🔄 IN PROGRESS - Test framework ready, execution pending

---

Overview

Implemented the core test infrastructure for end-to-end integration testing of the Attune platform. Created a comprehensive Python test suite with pytest, API client wrapper, and automated test runner. The framework is ready to validate all 5 services working together (API, Executor, Worker, Sensor, Notifier).

---

Completed Tasks

1. E2E Test Suite Implementation ✅

Created comprehensive pytest test suite (tests/test_e2e_basic.py - 451 lines):

AttuneClient API Wrapper:

• Full REST API client with authentication
• JWT token management with automatic login
• HTTP retry logic for resilience
• Complete CRUD operations for all entities:
  • Packs (register, get)
  • Actions (create, get)
  • Triggers (create, get)
  • Sensors (create, get)
  • Rules (create, get)
  • Events (list, get)
  • Executions (list, get, wait for status)
• Polling helper: wait_for_execution_status() with timeout

Test Fixtures:

• client - Session-scoped authenticated API client
• test_pack - Registers test pack once per session
• unique_ref - Generates unique resource identifiers per test

Test Scenarios Implemented:

1. ✅ API health check (with correct /health endpoint)
2. ✅ Authentication and JWT token generation (with /auth/login)
3. ✅ Automatic user registration fallback
4. ✅ Pack registration from local directory
5. ✅ Action creation with parameters
6. ✅ Timer trigger + rule creation (infrastructure)
7. ✅ Manual action execution (if endpoint exists)

Key Features:

• Configurable API URL and timeouts via environment variables
• Automatic cleanup of test resources
• Rich error messages with context
• Retry logic for flaky network conditions
• Proper status code validation

2. Test Dependencies Management ✅

• pytest-asyncio>=0.21.0 - Async test support
• pytest-timeout>=2.1.0 - Test timeout enforcement
• pytest-xdist>=3.3.0 - Parallel test execution

HTTP & WebSocket:

• requests>=2.31.0 - HTTP client
• websockets>=11.0.0 - WebSocket client for notifier tests

• pytest-json-report>=1.5.0 - JSON test reports
• pytest-cov>=4.1.0 - Code coverage

3. Test Runner Script ✅

Created automated test runner (tests/run_e2e_tests.sh - 242 lines):

Features:

• Automatic virtual environment creation
• Dependency installation
• Service health checks (validates API is running)
• Environment variable configuration
• Colored console output with progress indicators
• Flexible test execution options:
  • -v, --verbose - Detailed test output
  • -s, --stop-on-fail - Fail fast mode
  • -k EXPRESSION - Filter tests by name
  • -m MARKER - Run tests by marker
  • --coverage - Generate coverage reports
  • --setup - Initialize test environment
  • --teardown - Clean up artifacts

Workflow:

1. Check/create virtual environment
2. Install test dependencies
3. Verify API service is reachable
4. Run pytest with configured options
5. Generate reports
6. Optional cleanup

Output:

• Clear status messages (info, success, warning, error)
• Professional formatting with box borders
• Exit codes for CI/CD integration
• HTML and JSON reports (optional)

Test Architecture

AttuneClient Design

class AttuneClient:
    - Wraps all API endpoints
    - Automatic authentication
    - Session management with retry logic
    - Consistent error handling
    - Helper methods for common patterns

Example Usage:

# Create and authenticate
client = AttuneClient("http://localhost:8080")
client.login()

# Register pack
pack = client.register_pack("/path/to/pack", skip_tests=True)

# Create action
action = client.create_action({
    "ref": "test.echo",
    "pack": "test",
    "runner_type": "python-script",
    "entry_point": "echo.py"
})

# Wait for execution
result = client.wait_for_execution_status(
    execution_id=123,
    target_status="succeeded",
    timeout=30
)

Test Flow Pattern

@pytest.mark.e2e
def test_automation_flow(client, test_pack, unique_ref):
    # 1. Setup: Create resources
    action = client.create_action(...)
    trigger = client.create_trigger(...)
    rule = client.create_rule(...)
    
    # 2. Action: Trigger automation
    # (via sensor or manual execution)
    
    # 3. Assert: Verify results
    execution = client.wait_for_execution_status(...)
    assert execution["status"] == "succeeded"
    
    # 4. Cleanup: (automatic via fixtures)

Test Scenarios Planned

Basic Tests (Phase 2)

• API health endpoint validation
• Authentication and token generation
• Pack registration from local directory
• Action creation with parameters
• Timer automation flow (NEXT - requires all services)
• Manual action execution (if endpoint available)
• Event creation and retrieval
• Execution lifecycle tracking

Advanced Tests (Phase 3)

• Workflow execution (3-task sequential)
• FIFO queue ordering (concurrency limits)
• Inquiry (human-in-the-loop) flows
• Secret management across services
• Error handling and retry logic
• WebSocket notifications
• Dependency isolation (per-pack venvs)

Technical Decisions

Why pytest?

• Industry standard for Python testing
• Rich plugin ecosystem (async, parallel, coverage)
• Excellent fixture system for test setup/teardown
• Clear, readable test syntax
• Great CI/CD integration

Why requests over httpx?

• More mature and stable
• Simpler API for synchronous tests
• Built-in retry logic via urllib3
• Wider adoption and documentation
• Can upgrade to httpx later for async tests

Why custom client over OpenAPI generator?

• Full control over error handling
• Custom retry and timeout logic
• Helper methods for common patterns (wait_for_status)
• No dependency on backend OpenAPI spec
• Easier to debug and maintain for tests

---

Lessons Learned

1. Service Dependencies: E2E tests require all services running, which is more complex than unit tests. Need good service management scripts.

2. Test Isolation: Each test should create unique resources to avoid conflicts when running in parallel.

3. Timeout Management: Always set timeouts on polling operations to avoid infinite hangs.

4. Error Context: Rich error messages with execution IDs and current state make debugging much easier.

5. Environment Setup: Automated setup/teardown reduces friction for new developers running tests.

---

Blockers & Risks

Current Blockers

1. Services Not Running: Tests require all 5 services to be running

   • Mitigation: Service health checks before running tests
   • Workaround: Skip tests that require unavailable services

2. Direct Execution Endpoint: May not exist yet

   • Mitigation: Test via rule/event flow instead
   • Workaround: Skip manual execution tests

Risks

1. Test Flakiness: Network issues, timing dependencies

   • Mitigation: Retry logic, generous timeouts, polling

2. Service Startup Order: Dependencies between services

   • Mitigation: Health checks, retry connections

3. Database State: Tests may interfere with each other

   • Mitigation: Use unique refs, test-specific database

API Endpoint and Schema Fixes

After initial testing, fixed several API endpoint URLs and request schema issues:

Issues Found:

1. Authentication endpoint was /auth/login but should be /auth/login
2. Health endpoint returned "ok" not "healthy"
3. No default admin user - tests need to register first
4. Auth field names incorrect: Used username instead of login, full_name instead of display_name
5. Password validation: Minimum 8 characters required (was using admin123)

Fixes Applied:

• Updated login() to use /auth/login (auth routes are at root, not under /api/v1)
• Updated _request() to check for correct login path
• Added register() method for user registration
• Added fallback registration in login() if user doesn't exist (401/404)
• Fixed health check assertion to expect "ok" status
• Fixed auth request fields: username → login, full_name → display_name
• Updated default password: admin123 → AdminPass123! (meets 8-char minimum)
• Created quick_test.py for manual validation without pytest

Corrected API Routes:

• Health: /health (root level, no versioning)
• Auth: /auth/* (root level, no versioning)
• API endpoints: /api/v1/* (versioned)

Corrected Auth Schema:

// Login Request
{
  "login": "user@example.com",      // NOT "username"
  "password": "SecurePass123!"      // Min 8 chars
}

// Register Request
{
  "login": "newuser@example.com",   // NOT "username", min 3 chars
  "password": "SecurePass123!",     // Min 8 chars, max 128
  "display_name": "New User"        // NOT "full_name", optional
}
