Follows up the CodeRabbit review nitpick on #527.

The CSP nonce tests only checked that a nonce attribute was present, so a script carrying the style nonce (or the reverse) would still pass, and the layout's style could satisfy the heatmap assertion on its own.

Changes in tests/TestCase/Controller/Admin/QueuedJobsControllerTest.php:

  • New assertTagsHaveNonce() helper that checks every <script>, <style> and <link rel="stylesheet"> tag for the exact expected nonce value.
  • Stats and heatmap tests set both cspScriptNonce and cspStyleNonce to different values and assert each element type gets its own.
  • The heatmap's own <style> block is asserted independently of the layout styles.
  • New precedence test: with both cspScriptNonce and cspNonce set, every script uses cspScriptNonce.

Tests only, no template changes.

Summary by CodeRabbit

  • Tests
    • Expanded coverage for content security policy nonce handling on queued-job statistics and heatmap pages. Checks now include nonces on scripts, inline styles, and stylesheet links, as well as which nonce is used when multiple values are available.

Presence-only checks accepted a script carrying the style nonce and the
reverse. Check every script, style and stylesheet link for its own nonce.

Walkthrough

The admin controller tests now verify CSP nonce values on statistics and heatmap response tags. They cover script and style nonces, stylesheet links, and precedence of cspScriptNonce over cspNonce.

Changes: CSP nonce test coverage

Layer / File(s) Summary
Verify nonce values in admin responses
tests/TestCase/Controller/Admin/QueuedJobsControllerTest.php
Statistics and heatmap tests check expected nonces on script, style, and stylesheet-link tags. The tests also check script nonce precedence and use shared tag assertion helpers.

Merge Risk: Minimal · previous review 7c10f

This is a test-only change with no production impact. It makes the CSP nonce assertions stricter, and the one remaining gap in stylesheet link coverage is minor.

match stylesheet as a rel token, including links with values such as alternate
stylesheet, so every stylesheet link is checked for the nonce.
