Status: ✅ COMPLETE
Component: Core Pack (packs/core)

---

Objective

Implement comprehensive unit tests for all Core Pack actions to ensure they operate correctly with valid inputs, handle errors appropriately, and maintain reliability.

---

Completed Work

1. Test Infrastructure Created

Files Created:

• packs/core/tests/run_tests.sh - Bash-based test runner (377 lines)
• packs/core/tests/test_actions.py - Python unittest suite (557 lines)
• packs/core/tests/README.md - Comprehensive testing documentation
• packs/core/tests/TEST_RESULTS.md - Test results and status tracking

Features Implemented:

• Color-coded test output (bash runner)
• Fast execution with minimal dependencies
• CI/CD ready with non-zero exit codes on failure
• Optional dependency handling (PyYAML, pytest)
• Parameterized tests for multiple scenarios
• Timing validation for sleep tests
• Network request testing for HTTP action
• File permission validation
• YAML schema validation

2. Test Coverage Achieved

Total Tests: 76 (36 bash + 38 Python + 2 skipped)

core.echo (7 tests)

• ✅ Basic echo with custom message
• ✅ Default message when none provided
• ✅ Uppercase conversion (true/false)
• ✅ Empty messages
• ✅ Special characters handling
• ✅ Multiline messages
• ✅ Exit code validation

core.noop (8 tests)

• ✅ Basic no-op execution
• ✅ Custom message logging
• ✅ Exit code 0 (success)
• ✅ Custom exit codes (1-255)
• ✅ Invalid negative exit codes (error)
• ✅ Invalid large exit codes >255 (error)
• ✅ Invalid non-numeric exit codes (error)
• ✅ Maximum valid exit code (255)

core.sleep (8 tests)

• ✅ Basic sleep (1 second)
• ✅ Zero seconds sleep
• ✅ Custom message display
• ✅ Default duration (1 second)
• ✅ Multi-second sleep with timing validation
• ✅ Invalid negative seconds (error)
• ✅ Invalid large seconds >3600 (error)

core.http_request (10 tests)

• ✅ Simple GET request
• ✅ Missing required URL (error)
• ✅ POST with JSON body
• ✅ Custom headers
• ✅ Query parameters
• ✅ Timeout handling
• ✅ 404 status code handling
• ✅ Different HTTP methods (PUT, PATCH, DELETE, HEAD, OPTIONS)

Additional Tests (4+ tests)

• ✅ File permissions (all scripts executable)
• ✅ YAML schema validation (pack.yaml, action YAMLs)
• ✅ Pack configuration structure
• ✅ Script existence verification

3. Bug Fixes

Issue: SECONDS Variable Conflict

• Problem: sleep.sh used SECONDS variable which conflicts with bash built-in that tracks shell uptime
• Impact: Sleep tests were reporting incorrect durations
• Solution: Renamed variable to SLEEP_SECONDS throughout the script
• File Modified: packs/core/actions/sleep.sh
• Status: ✅ Resolved

Issue: Empty Message Test Expectation

• Problem: Python test expected empty output, but bash echo with empty string outputs newline
• Solution: Adjusted test expectation to account for bash behavior
• Status: ✅ Resolved

Issue: HTTP POST JSON Test

• Problem: Test expected wrong response structure from httpbin.org
• Solution: Updated test to parse nested JSON response correctly
• Status: ✅ Resolved

Technical Details

Test Methodology

Bash Test Runner (run_tests.sh):

• Executes action scripts directly with environment variables
• Captures stdout, stderr, and exit codes
• Validates output contains expected strings
• Tests for both success and expected failures
• Color-coded results (green=pass, red=fail, yellow=skip)

Python Test Suite (test_actions.py):

• Uses unittest framework (pytest compatible)
• Structured test classes per action
• setUp/tearDown lifecycle support
• Subprocess execution with timeout
• JSON parsing for HTTP responses
• Timing validation for sleep tests

Test Infrastructure Features

1. Optional Dependency Handling

   • Tests run even if PyYAML not installed
   • Tests run even if pytest not installed
   • HTTP tests skip if requests not available
   • Clear messages for skipped tests

2. Cross-Platform Compatibility

   • Works on Linux, macOS
   • Bash-based tests use portable shell features
   • Python tests use subprocess for portability

3. CI/CD Integration

   • Non-zero exit codes on failure
   • Structured output for parsing
   • Fast execution (<30 seconds total)
   • No interactive prompts

4. Error Validation

   • Tests verify error messages are helpful
   • Exit codes match expected values
   • Invalid inputs properly rejected
   • Boundary conditions tested

Programmatic Testing Framework Design

Design Document Created

In response to the need for automatic test execution during pack installation, a comprehensive Pack Testing Framework design has been created:

Document: docs/pack-testing-framework.md (831 lines)

Key Features

1. Pack Manifest Extension

• Added testing section to pack.yaml format
• Specifies test runners by runtime type
• Configurable test discovery methods
• Pass/fail criteria and failure handling

2. Test Discovery Methods

• Directory-based (recommended)
• Manifest-based (explicit listing)
• Executable-based (single command)

3. Test Execution Workflow

• Automatic during pack installation
• CLI command: attune pack test <pack>
• Worker service executes tests in appropriate runtime
• Results stored in database for auditing

4. Standardized Results Format

PackTestResult {
    total_tests, passed, failed, skipped,
    pass_rate, duration_ms,
    test_suites: Vec<TestSuiteResult>
}

5. Database Schema

• pack_test_execution table for tracking test runs
• pack_test_summary view for latest results
• Test result history for auditing

6. CLI Integration

attune pack test ./packs/my_pack
attune pack install ./packs/my_pack  # tests run automatically
attune pack install ./packs/my_pack --skip-tests

Core Pack Configuration

Updated packs/core/pack.yaml with testing section:

testing:
  enabled: true
  discovery:
    method: "directory"
    path: "tests"
  runners:
    shell:
      entry_point: "tests/run_tests.sh"
      timeout: 60
    python:
      entry_point: "tests/test_actions.py"
      timeout: 120
  min_pass_rate: 1.0
  on_failure: "block"

Implementation Phases

Phase 1: Core Framework (Design Complete)

• ✅ Design document created
• ✅ Core pack tests implemented
• ✅ pack.yaml testing configuration added
• ⏳ Database schema (next step)
• ⏳ Worker test executor (next step)

Phase 2: Worker Integration (Planned)

• Test executor in worker service
• Output parsers (simple, JUnit XML, TAP)
• Test result storage
• Error handling and timeouts

Phase 3: CLI Integration (Planned)

• attune pack test command
• Integration with pack install workflow
• Force/skip test options
• Test result display

Phase 4: Advanced Features (Future)

• API endpoints for test results
• Web UI for viewing test history
• Test caching and optimization
• Parallel test execution

Benefits

1. Fail-Fast Installation: Packs don't activate if tests fail
2. Dependency Validation: Verify all dependencies present before activation
3. Confidence: Tests run in actual deployment environment
4. Audit Trail: Test results stored for compliance
5. Quality Assurance: Encourages pack authors to write tests

---

Next Steps:

1. The test infrastructure is ready for adding tests for any new actions, sensors, or triggers added to the Core Pack in the future
2. Implement Phase 1 of the Pack Testing Framework (database schema and worker test executor) to enable programmatic test execution during pack installation
3. Consider running these tests as part of the CI/CD pipeline to catch regressions early
