XcodeBuildMCP Test Boundary Review

Review guardrails for test isolation, scope, and contract validation.

Review scope

• Review-only by default.
• Do not edit product code unless the user explicitly requests implementation changes.

Files to inspect

• src/**/__tests__/**
• src/test-utils/**
• src/snapshot-tests/**
• scripts/**/__tests__/**
• package.json
• xcodebuildmcp.com/app/docs/_content/testing.mdx
• xcodebuildmcp.com/app/docs/_content/contributing.mdx

Guardrails

• Unit tests inject command/filesystem/external dependencies.
• Unit tests do not call real xcodebuild, xcrun, AXe, devices, or simulators.
• Prefer testing logic/executor functions over handler wrappers unless testing runtime integration.
• Use existing mock executor helpers.
• Treat snapshot updates as contract changes requiring review.
• Do not add fake e2e/snapshot state to force test success.
• Avoid unsafe TypeScript suppressions.

Validation

• Run targeted Vitest command for touched tests.
• npm test
• npm run typecheck
• If fixtures/schemas changed: npm run test:snapshots and npm run test:schema-fixtures
• npx skill-check .agents/skills/xcodebuildmcp-test-boundary-review
