13 tests judged in this suite · 19 not judged.

53.7%22 of 41 subtests

Coverage — 35.7%: of the 115 subtests wpt.fyi runs in this directory we judge 41. The rest we do not run at all, so no figure above speaks for them.

By tests — the unit Interop counts — 38.5%: 5 of 13. A file is one test and passes only when every subtest in it passes, so this figure is the stricter of the two.

All 32 of them, grouped by the directory the corpus keeps them in — passes included. Open a directory to see what each test checks; open a test to see our render, the reference, the pixels that differ, and the source of both files.
