Two test cases:

  1. test_interval_timer_creates_executions - Main test

    • Creates 5-second interval timer
    • Verifies 3 executions in ~15 seconds
    • Checks timing precision (±1.5s tolerance)
    • Validates event → enforcement → execution flow
  2. test_interval_timer_precision - Precision test

    • Tests 3-second interval over 5 fires
    • Calculates interval statistics (avg, min, max)
    • Verifies ±1 second precision

Success Criteria:

  • Timer fires every N seconds with acceptable precision
  • Each event creates enforcement and execution
  • All executions succeed
  • No service errors

T1.2: Date Timer (One-Shot Execution)

Three test cases:

  1. test_date_timer_fires_once - Main test

    • Schedules timer 5 seconds in future
    • Verifies fires exactly once
    • Checks timing precision (±2s tolerance)
    • Waits additional 10s to verify no duplicate fires
  2. test_date_timer_past_date - Edge case

    • Creates timer with past date
    • Verifies either fires immediately OR fails gracefully
    • Ensures one-shot behavior
  3. test_date_timer_far_future - Edge case

    • Creates timer 1 hour in future
    • Verifies doesn't fire prematurely
    • Validates sensor correctly waits

Success Criteria:

  • Timer fires once at scheduled time
  • Exactly 1 event and 1 execution

Four test cases:

  1. test_webhook_trigger_with_payload - Main test

    • Creates webhook trigger
    • POSTs JSON payload
    • Verifies event payload matches POST body
    • Validates execution receives webhook data
  2. test_multiple_webhook_posts - Multiple invocations

    • Fires webhook 3 times
    • Verifies 3 events and 3 executions
    • Validates all complete successfully
  3. test_webhook_with_complex_payload - Nested data

    • POSTs complex nested JSON structure
    • Verifies structure preserved in event
    • Validates nested path access
  4. test_webhook_without_payload - Empty payload

    • Fires webhook with empty body
    • Verifies system handles gracefully

Success Criteria:

  • Webhook POST creates event immediately
  • Event payload matches POST body
  • Execution receives webhook data

Comprehensive bash script for running tests:

Features:

  • Colored output (info, success, warning, error)
  • Service health check (API availability)
  • Automatic environment setup (venv, dependencies)
  • Tier-based test execution (--tier 1)
  • Verbose output (-v)

Testing Best Practices Established

  1. Test Isolation:

    • Each test creates unique resources
    • No shared state between tests
    • unique_ref() prevents naming conflicts
  2. Clear Test Structure:

    • Descriptive test names
    • Step-by-step execution
    • Print statements for debugging
    • Summary at end of test
  3. Robust Waiting:

    • Polling with timeouts
    • Configurable intervals
    • Clear timeout errors
    • Multiple wait strategies
  4. Comprehensive Assertions:

    • Verify all success criteria
    • Check intermediate states
    • Validate timing/precision
    • Test edge cases
  5. Good Documentation:

    • Docstrings on all tests
    • Quick start guide
    • Troubleshooting section
    • Example outputs

Known Limitations

  1. Service Dependency: Tests require all 5 services running

    • Could add service availability checks
    • Could implement service mocking for unit tests
  2. Timing Sensitivity: Timer tests sensitive to system load

    • Have tolerance built in (±1-2 seconds)
    • May be flaky on heavily loaded systems
  3. Cleanup: Tests don't clean up created resources

    • Could add automatic cleanup in teardown
    • Could use test database that gets reset
  4. Parallel Execution: Tests not designed for parallel runs

    • Use unique references to enable parallelism
    • Could add pytest-xdist support
