Summary

scripts/mkdocs_hooks.py (the post-build hook that writes redirect stubs for old Sphinx URLs and retired pages) is the only code in this repository, and no test imported it. This adds tests/mkdocs_hooks_test.py, which the existing docs-sync job already runs (pytest tests/). No workflow change.

scripts/mkdocs_hooks.py Before After
Statements 0 / 17 (0%) 17 / 17 (100%)
Branches 0 / 6 6 / 6 (100%)

What the tests check:

  • every entry in MOVED_URLS gets <old>/index.html and every entry in LEGACY_URLS gets <name>.html, each pointing at the right target;
  • a stub carries the canonical link, the meta refresh, and the script that keeps #cc003;
  • a site URL without a trailing slash (deploy previews) and no site URL at all both join correctly;
  • on Netlify (NETLIFY=true) only the retired-page stubs are written;
  • a stub never overwrites a page the build wrote;
  • no stub redirects to another stub, and rules/ and configuration/ (linked from every released CLI) are never moved.

Note on CI

The docs-sync job will be red on this PR for a reason outside it: commit-check v2.19.3 is now on PyPI, and test_pinned_revisions_match_the_released_version fails because configuration.md, example.md and guides/pre-commit.md still pin v2.19.2. The next run on main fails the same way. That needs its own version bump PR.

Test plan

  • pytest tests/ with commit-check==2.19.3: the 8 new tests pass; the only failure is the version pin above.
  • coverage run --branch --include='scripts/*' -m pytest tests/: 100%.

Summary by CodeRabbit

  • Tests
    • Added coverage for redirects involving moved and legacy URLs, including trailing slashes, site URL settings, and URL fragments.
    • Added checks for Netlify redirect pages, existing page preservation, valid redirect targets, and retention of CLI-linked pages.

scripts/mkdocs_hooks.py is the site's only code and had no tests. Cover
both hosts (Netlify skips the .html stubs), site URLs with and without a
trailing slash or none at all, and two invariants the comments state: no
stub redirects to another, and rules/ and configuration/ never move.

📝 Walkthrough

Adds tests for the MkDocs post-build hook. The tests check redirect stub generation, redirect content and targets, Netlify output, preservation of existing pages, and URL exclusions.

Changes: Redirect hook test coverage

Layer / File(s) Summary
Redirect stub generation and edge cases
tests/mkdocs_hooks_test.py
Adds temporary-site test setup and assertions for stub paths, redirect content, URL joining, Netlify output, existing pages, retired targets, and excluded moved URLs.

Merge Risk: 🔵 Low · up to f5bc6

The PR is low risk, but two future-regression paths in the redirect-hook tests remain unguarded and should be tightened.

Include flat legacy stubs in the redirect-chain check.

The current cli mapping targets configuration/, but the assertion does not guard against a legacy mapping that targets another generated stub such as rules.html. Add the generated legacy paths to the forbidden destinations.

Suggested fix
     retired = {f"{old}/" for old in hooks.MOVED_URLS}
+    retired.update(f"{legacy}.html" for legacy in hooks.LEGACY_URLS)
     for target in [*hooks.MOVED_URLS.values(), *hooks.LEGACY_URLS.values()]:

Update the redirect-chain check in the test to add each generated flat legacy
stub path, formed from the keys in hooks.LEGACY_URLS with the .html suffix, to
the retired destinations before checking targets from MOVED_URLS and
LEGACY_URLS.

Normalize protected route keys before asserting them.

MOVED_URLS uses each key directly in site / old / "index.html". A future "rules/" or "configuration/" key would therefore overwrite the corresponding page, while the current assertions would still pass.

Suggested test correction
-    assert "rules" not in hooks.MOVED_URLS
-    assert "configuration" not in hooks.MOVED_URLS
+    protected = {old.rstrip("/") for old in hooks.MOVED_URLS}
+    assert "rules" not in protected
+    assert "configuration" not in protected

Update the protected-route assertions near the MOVED_URLS checks to compare
normalized keys by stripping trailing slashes from each old route before
checking for “rules” and “configuration,” so slash-suffixed keys are also
rejected.
