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
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
Fixed configuration:
- Updated
.zerg/config.yamlto match new ZergConfig schema - quality_gates as list of QualityGate objects
- mcp_servers as list of strings
- Updated
Implemented 8 test files (79 tests total):
conftest_container.py- Shared fixtures and helperstest_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)
Fixed API mismatches:
write_to_file→write_devcontainer(languages, output_dir)ContainerLauncher.docker_available()→ localdocker_cli_available()helperimage_exists(image_name)→image_exists()(uses self.image_name)- Orchestrator tests rewritten to use
isinstance()checks
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
tasksmust be an array, not a dictfilesmust 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 firstContainerLauncher(image_name=...)- image_name at init, not per-call- Orchestrator has
.launcherattribute, useisinstance()for type checks
Next Steps
- Container dogfooding plan available at
claudedocs/plan-container-dogfooding.md - Continue toward 100% test coverage effort
- Consider running ZERG rush to validate task graph execution
