Frequently asked questions

How do I detect a broken image in a test?

Evaluate el.naturalWidth on #broken-assets-img-1 … -4 — a broken image reports zero — or watch the network for the 404s. Exactly two of the four are broken, pointing at /gallery/… paths that do not exist.

How do I check links for dead targets?

Request each href from #broken-assets-link-1 … -4 and assert the status rather than clicking through. Exactly two return 404. This is also the one page on the site that legitimately logs failed image requests to the console.
