Make the uppercase .SVG test independent of MIME filtering.
HTML_WITH_UPPERCASE_SVG_ONLY declares type="image/svg+xml". The separate MIME check can therefore make the test pass if the suffix check becomes case-sensitive or is removed. Remove the type attribute so the test verifies uppercase suffix handling.

For the last question, I don't think it is out of scope. |
Cover the common favicon cases described in the issue: case-insensitive `.svg` suffixes, `type="image/svg+xml"`, `sizes="any"`, and multiple `rel` tokens. Reset fetch-mock in an `afterEach` hook so the cleanup runs even when a test fails, keeping each test isolated from the others. Assisted-by: Claude Code:claude-opus-4-8
- Adds the `g` flag so every declared size is matched, not just the first. - Rewrites the size check to keep the icon when any single size is large enough. Assisted-by: Claude Code:claude-opus-4-8

Use a candidate URL distinct from the fallback.
If getFaviconUrl() rejects the multi-size icon, it returns /favicon.ico through its fallback. The test can therefore pass without checking multi-size selection. Use a different candidate URL and assert that URL.

Summary
Improve favicon selection by adding tests and detecting SVG favicons via the
typeattribute ingetFaviconUrl()(packages/cli/src/nodeinfo.ts).Related issue
fedify nodeinfo#893Changes
getFaviconUrl()covering multiplereltokens, SVG skipping (.svgsuffix, uppercase, query/hash, andtype="image/svg+xml"),sizes="any", and bitmap preference.mise run test:deno packages/cli/src/nodeinfo.test.ts, I noticed that when an earlier test fails, its trailingfetchMock.hardReset()never runs and leaks mock state into later tests. I added anafterEach()hook so each test stays isolated regardless of failures.getFaviconUrl()that detects SVG favicons declared via thetype="image/svg+xml"attribute.AI disclosure
Claude Code (
claude-opus-4-8) was used as an advisor: it reviewed my code and helped investigate behavior.Notes
getFaviconUrl()logic, when an icon declares multiple sizes (e.g., hackers.pub's16x16 32x32 … 256x256), only the first size is checked; if that one is too small, the icon is discarded even though a larger256x256is available, and the selector falls back to the next candidate (the apple-touch-icon, 180px).I'd like to fix this so it considers all declared sizes and does not skip the
256x256. Would this fix fit the scope of the current issue, or should I open a new issue for it?
