Session: DC-012 Integration Tests

Date: 2026-01-27 Status: COMPLETE Feature: Dynamic Devcontainer Integration Tests

Session Summary

Implemented DC-012 integration tests for the dynamic devcontainer feature using ZERG methodology.

Accomplishments

1. Created task infrastructure:

   • .gsd/specs/dc-012-integration-tests/task-graph.json - ZERG task graph
   • .gsd/tasks/dc-012-integration-tests/BACKLOG.md - Task backlog
   • 9 prompt files for worker execution

2. Fixed configuration:

   • Updated .zerg/config.yaml to match new ZergConfig schema
   • quality_gates as list of QualityGate objects
   • mcp_servers as list of strings

3. Implemented 8 test files (79 tests total):

   • conftest_container.py - Shared fixtures and helpers
   • test_container_detection.py - Multi-language detection (2 tests)
   • test_container_devcontainer.py - Devcontainer generation (3 tests)
   • test_container_launcher_checks.py - Launcher availability (3 tests)
   • test_container_orchestrator.py - Orchestrator mode selection (2 tests)
   • test_container_init_cmd.py - Init command CLI (1 test)
   • test_container_rush_cmd.py - Rush --mode flag (1 test)
   • test_container_e2e.py - End-to-end flow (1 test)

4. Fixed API mismatches:

   • write_to_file → write_devcontainer(languages, output_dir)
   • ContainerLauncher.docker_available() → local docker_cli_available() helper
   • image_exists(image_name) → image_exists() (uses self.image_name)
   • Orchestrator tests rewritten to use isinstance() checks

5. Updated backlog: Marked DC-012 complete (12/12 tasks, 100%)

Verification

pytest tests/integration/test_container_*.py -v
# Result: 79 passed

Commit

47acd5f test: add DC-012 container integration tests (79 tests)

Technical Learnings

ZergConfig Schema

quality_gates:
  - name: lint
    command: ruff check .
    required: true
    timeout: 300
mcp_servers:
  - filesystem  # strings, not dicts

Task Graph Schema

• tasks must be an array, not a dict
• files must be {create: [], modify: [], read: []}
• Levels must be >= 1 (1-indexed)
• Dependencies must be in lower levels

API Patterns

• DynamicDevcontainerGenerator.write_devcontainer(languages, output_dir) - languages first
• ContainerLauncher(image_name=...) - image_name at init, not per-call
• Orchestrator has .launcher attribute, use isinstance() for type checks

Next Steps

1. Container dogfooding plan available at claudedocs/plan-container-dogfooding.md
2. Continue toward 100% test coverage effort
3. Consider running ZERG rush to validate task graph execution
