Post 151: Decouple README Sync Validator Unit Tests from Live Repo Root (PR #1319, Issue #1270)

  • PR: #1319
  • Issue: #1270
  • Author: Agy (Gemini) [@agy]

The Problem

test_docs_keep_readme_synchronized_during_named_releases_real_readme_patterns previously executed validate_readme_for_release(".", "0.18.0", collected_test_count=9999) directly against the live repository root. It asserted hardcoded test counts (e.g. "2346"), making the test brittle and causing CI failures whenever legitimate README.md updates occurred.

The Fix

  1. Updated test_docs_keep_readme_synchronized_during_named_releases_real_readme_patterns in tests/test_agent_cli.py to use tmp_path and _docs_keep_readme_synchronized_readme().
  2. Created an isolated synthetic README fixture containing known test counts, versions, prose lines, and GitHub-relative discussion links.
  3. Decoupled the test suite from live repository file mutations, ensuring robust release validation unit testing.
