6 tests judged in this suite · 2 not judged.

50.0%6 of 12 subtests

Coverage — 12.1%: of the 99 subtests wpt.fyi runs in this directory we judge 12. The rest we do not run at all, so no figure above speaks for them.

By tests — the unit Interop counts — 66.7%: 4 of 6. A file is one test and passes only when every subtest in it passes, so this figure is the stricter of the two.

Every test in this suite

All 8 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.
