Completed Work

1. Database Migration

File: migrations/20260120200000_add_pack_test_results.sql (154 lines)

Tables Created:

• attune.pack_test_execution - Main table for test execution tracking
  • Stores complete test results as JSONB
  • Tracks pass/fail counts, pass rate, duration
  • Links to pack with CASCADE delete
  • Supports trigger reasons: install, update, manual, validation

Views Created:

• attune.pack_test_summary - All test executions with pack details
• attune.pack_latest_test - Latest test result per pack

Functions Created:

• get_pack_test_stats(pack_id) - Statistical summary
• pack_has_passing_tests(pack_id, hours_ago) - Recent test validation
• update_pack_test_metadata() - Trigger function for metadata updates

Indexes:

• idx_pack_test_execution_pack_id - Fast pack lookup
• idx_pack_test_execution_time - Time-based queries
• idx_pack_test_execution_pass_rate - Filter by success rate
• idx_pack_test_execution_trigger - Filter by trigger reason

Constraints:

• Valid test counts (non-negative)
• Valid pass rate (0.0 to 1.0)
• Valid trigger reasons (install, update, manual, validation)

2. Data Models

File: crates/common/src/models.rs

Models Added:

// Database record
PackTestExecution {
    id, pack_id, pack_version, execution_time,
    trigger_reason, total_tests, passed, failed,
    skipped, pass_rate, duration_ms, result, created
}

// Test execution structure
PackTestResult {
    pack_ref, pack_version, execution_time,
    total_tests, passed, failed, skipped,
    pass_rate, duration_ms, test_suites[]
}

// Test suite (per runner type)
TestSuiteResult {
    name, runner_type, total, passed, failed,
    skipped, duration_ms, test_cases[]
}

// Individual test case
TestCaseResult {
    name, status, duration_ms,
    error_message, stdout, stderr
}

// Test status enum
TestStatus: Passed | Failed | Skipped | Error

// View models
PackTestSummary - Summary with pack details
PackLatestTest - Latest test per pack
PackTestStats - Statistical aggregation

3. Repository Layer

File: crates/common/src/repositories/pack_test.rs (410 lines)

Methods Implemented:

Creation:

• create(pack_id, pack_version, trigger_reason, result) - Record test execution

Retrieval:

• find_by_id(id) - Get specific test execution
• list_by_pack(pack_id, limit, offset) - Paginated pack tests
• get_latest_by_pack(pack_id) - Most recent test
• get_all_latest() - Latest test for all packs

Statistics:

• get_stats(pack_id) - Full statistical summary
  • Total executions, successful, failed
  • Average pass rate and duration
  • Last test time and status
• has_passing_tests(pack_id, hours_ago) - Recent validation

Filtering:

• list_by_trigger_reason(reason, limit, offset) - Filter by trigger
• get_failed_by_pack(pack_id, limit) - Failed executions only
• count_by_pack(pack_id) - Count total tests

Maintenance:

• delete_old_executions(days_old) - Cleanup old test data

Tests:

• Unit tests for all major operations (3 tests implemented)
• Tests marked as #[ignore] (require database)
• Coverage for creation, retrieval, statistics

4. Design Documentation

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

Sections:

1. Overview - Purpose and design principles
2. Pack Manifest Extension - pack.yaml testing configuration
3. Test Discovery Methods - Directory, manifest, executable
4. Test Execution Workflow - Installation flow and test process
5. Test Result Format - Standardized JSON structure
6. Database Schema - Complete schema documentation
7. Worker Service Integration - Test executor design
8. CLI Commands - Command specifications
9. Test Result Parsers - JUnit XML, TAP, simple formats
10. Pack Installation Integration - Modified workflow
11. API Endpoints - REST API design
12. Best Practices - Guidelines for pack authors
13. Implementation Phases - Phased rollout plan

Key Features Designed:

• Runtime-aware testing (shell, Python, Node.js)
• Fail-fast installation (tests must pass)
• Standardized result format across all runner types
• Database tracking for audit trail
• Configurable failure handling (block, warn, ignore)

5. Pack Configuration

File: packs/core/pack.yaml

Added Testing Section:

testing:
  enabled: true
  discovery:
    method: "directory"
    path: "tests"
  runners:
    shell:
      type: "script"
      entry_point: "tests/run_tests.sh"
      timeout: 60
      result_format: "simple"
    python:
      type: "unittest"
      entry_point: "tests/test_actions.py"
      timeout: 120
      result_format: "simple"
  result_path: "tests/results/"
  min_pass_rate: 1.0
  on_failure: "block"

Benefits:

• Core pack now discoverable for testing
• Configuration demonstrates best practices
• Ready for automatic test execution

Technical Implementation Details

Database Design Decisions

1. JSONB for Full Results: Store complete test output for debugging
2. Separate Summary Fields: Fast queries without JSON parsing
3. Views for Common Queries: pack_latest_test for quick access
4. Functions for Statistics: Reusable logic in database
5. Trigger Reasons: Track why tests were run (install vs manual)
6. CASCADE Delete: Clean up test results when pack deleted

Model Architecture

1. Separation of Concerns:

   • PackTestExecution - Database persistence
   • PackTestResult - Runtime test execution
   • Conversion handled in repository layer

2. Type Safety:

   • Strongly typed enums for test status
   • SQLx FromRow for database mapping
   • Serde for JSON serialization

3. Extensibility:

   • JSONB allows schema evolution
   • Test suites support multiple runner types
   • Test cases capture stdout/stderr for debugging

Repository Patterns

1. Consistent API: All repositories follow same patterns
2. Error Handling: Uses common Result<T> type
3. Async/Await: All operations are async
4. Connection Pooling: Reuses PgPool efficiently
5. Testing: Unit tests with #[ignore] for database dependency

Next Steps (Phase 2)

1. Worker Test Executor Implementation

File: crates/worker/src/test_executor.rs

Requirements:

• Parse pack.yaml testing configuration
• Discover test runners by type
• Execute tests with timeout protection
• Parse output (simple format initially)
• Create PackTestResult structure
• Store results via PackTestRepository

Pseudocode:

struct TestExecutor {
    runtime_manager: Arc<RuntimeManager>,
    test_repo: PackTestRepository,
}

impl TestExecutor {
    async fn execute_pack_tests(
        pack_dir: &Path,
        pack_id: i64,
    ) -> Result<PackTestResult> {
        // 1. Load pack.yaml
        // 2. Parse testing config
        // 3. For each runner type:
        //    - Get runtime
        //    - Execute test script
        //    - Parse output
        //    - Collect results
        // 4. Aggregate results
        // 5. Store in database
        // 6. Return result
    }
}

2. Simple Output Parser

File: crates/worker/src/test_parsers/simple.rs

Requirements:

• Parse our bash test runner output format
• Extract: "Total Tests:", "Passed:", "Failed:"
• Create TestSuiteResult from parsed data
• Handle errors gracefully

Format:

Total Tests:  36
Passed:       36
Failed:       0
✓ All tests passed!

3. CLI Integration

File: crates/cli/src/commands/pack.rs

New Command: attune pack test <pack>

Requirements:

• Load pack from filesystem or registry
• Call worker test executor
• Display results with colors
• Exit with appropriate code (0=pass, 1=fail)

Options:

• --verbose - Show detailed test output
• --runtime <type> - Test specific runtime only

4. Pack Install Integration

File: crates/cli/src/commands/pack.rs

Modify: install_pack() function

Requirements:

• Check if testing enabled in pack.yaml
• Run tests before activation
• Handle failure based on on_failure setting
• Store results in database
• Display test summary

Options:

• --skip-tests - Skip testing
• --force - Install even if tests fail

---

Testing Strategy

Unit Tests (Completed)

• ✅ Repository unit tests (3 tests)
• ✅ Model serialization tests (via serde)

Integration Tests (Planned)

• End-to-end test execution
• Database result storage
• CLI command testing
• Pack install with tests

Manual Testing (Planned)

# Test core pack
attune pack test core

# Test with verbose output
attune pack test core --verbose

# Install with testing
attune pack install ./packs/my_pack

# Install skipping tests
attune pack install ./packs/my_pack --skip-tests

---

Performance Considerations

Database

• Indexes on common query patterns (pack_id, time, pass_rate)
• JSONB for flexible storage without schema changes
• Views for fast common queries
• Function for statistics to avoid repeated logic

Test Execution

• Timeouts prevent hanging tests
• Parallel execution possible (future enhancement)
• Test caching can speed up repeated runs (future)

Cleanup

• delete_old_executions() for pruning old data
• CASCADE delete removes tests when pack deleted
• Configurable retention period
