XcodeBuildMCP Snapshot Fixture Review

Review guardrails for fixture and snapshot contract integrity.

Review scope

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

Files to inspect

  • src/snapshot-tests/fixtures/**
  • src/snapshot-tests/contracts.ts
  • src/snapshot-tests/fixture-io.ts
  • src/snapshot-tests/tests/fixture-io.test.ts
  • src/snapshot-tests/tests/json-normalize.test.ts
  • src/snapshot-tests/tests/json-fixture-schema.test.ts
  • xcodebuildmcp.com/app/docs/_content/testing.mdx

Guardrails

  • Fixture updates map to intentional behavior changes.
  • Do not update fixtures only to make tests pass.
  • MCP, CLI, and JSON fixture updates stay aligned.
  • JSON fixtures preserve stable structured output envelopes.
  • Volatile values are normalized in code, not patched ad hoc in fixtures.
  • Missing fixtures are generated through the snapshot update flow.
  • Verify project-defined normalization sentinels in normalization code and tests before reporting

them as implausible fixture values. In particular, 99999 is an intentional sentinel for volatile UI capture counts.

  • Group every occurrence of the same root cause into one finding and list the affected fixtures.

Do not emit separate findings for equivalent CLI, MCP, text, or JSON drift.

  • Do not repeat a finding that is already resolved by the current diff.

Review limits

  • Review the changed fixtures and the directly relevant normalization or contract code only.
  • Do not run snapshot or smoke suites as part of an automated PR review.
  • Prefer one high-confidence cross-fixture finding over multiple speculative discrepancies.
