Sizing

560 tests judged in this suite · 11 not judged.

98.3%1,895 of 1,927 subtests

Coverage — 29.4%: of the 6,548 subtests wpt.fyi runs in this directory we judge 1,927. The rest we do not run at all, so no figure above speaks for them.

By tests — the unit Interop counts — 99.1%: 555 of 560. 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 571 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.

Judged by assertions

95 files in this suite state what they expect in the markup or as a parser assertion rather than as a second rendering. Each one counts as its subtests in the figures above.
