Plan 2: Testing Infrastructure & Core Logic

[iamladi]

Overview

Implement mock adapters for testing and port workflow state management as pure functions (Functional Core).

Research Source

• research/research-workflows-tdd-migration-deep.md
• Migration Roadmap Phase 2 (Tasks 3-5)

Tasks

• Create src/adapters/mocks/mock-github.ts implementing IGitHubClient
• Create src/adapters/mocks/mock-claude.ts implementing IClaudeClient
• Create src/adapters/mocks/mock-process.ts implementing IProcessRunner
• Create src/core/workflow-state.ts with WorkflowState type
• Create tests/unit/core/workflow-state.test.ts

Complexity

5/10

Acceptance Criteria

• Mock adapters implement all port interfaces
• WorkflowState type covers: setup, planning, implementing, completed, failed
• State transitions are pure functions (no side effects)
• Unit tests pass without vi.mock

Dependencies

• Depends on: Plan 1: Foundation Setup - TypeScript + Vitest + Ports #4
