Phase 7 Plan 01: MockAgentManager Adapter Summary

MockAgentManager adapter implementing AgentManager port with configurable scenarios (success, crash, waiting_for_input) for E2E test isolation

Performance

• Duration: 2 min
• Started: 2026-01-31T07:40:58Z
• Completed: 2026-01-31T07:43:18Z
• Tasks: 2
• Files modified: 3

Accomplishments

• MockAgentManager class implementing full AgentManager port interface
• MockAgentScenario interface for configuring agent behavior (outcome, delay, message, filesModified, question)
• setScenario() for per-agent scenario overrides
• All lifecycle events emitted: agent:spawned, agent:stopped, agent:crashed, agent:waiting, agent:resumed
• Comprehensive test suite with 28 test cases

Task Commits

Each task was committed atomically:

1. Task 1: Implement MockAgentManager adapter - 6148af7 (feat)
2. Task 2: Write comprehensive tests for MockAgentManager - e305375 (test)

Files Created/Modified

• src/agent/mock-manager.ts - MockAgentManager adapter with scenario configuration
• src/agent/mock-manager.test.ts - 28 comprehensive tests covering all scenarios
• src/agent/index.ts - Export MockAgentManager and MockAgentScenario

Decisions Made

• In-memory Map for agent storage: No database needed for mock adapter - tests don't need persistence
• setTimeout for async completion: Even with delay=0, completion happens via setTimeout for consistent async behavior in tests
• Resume completes successfully by default: After resume, agents complete with success to simplify test scenarios (can be overridden if needed)
• clear() method for test cleanup: Allows tests to reset state between runs

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• MockAgentManager ready for use in E2E tests
• Can be injected in place of ClaudeAgentManager via dependency injection
• All scenario types proven working: success, crash, waiting_for_input
• Event emission verified for integration with dispatch/coordination testing
