Web Test Fail/Skipped Counts

The table below is derived from the actual test expectations for recent try bot runs: linux-blink-rel 80390, mac-11-blink-rel 7485, win10.20h2-blink-rel 3887. Counts include virtual test suites owned by the team or testing stable functionality.

wpt/editing was added to the counts.

All test failures:

• Linux 3375 up 112

• Mac 3564 up 102

• Win 3287 up 82

Delta in the table below is the rounded average of the platforms.

Launch Test Status

Regressions are how many fail in the virtual suite while passing in the default.

Passing compares the virtual / default passing test counts.

Failing/Timeout compares virtual / default failing or timeout results

Skipped compares skipped count for virtual / default

• backface-visibility-interop: Need to update tracking for linux only

• controls-refresh-hc: Regressions 0, Passing 55 / 56, Failing/Timeout 0 / 0, Skipped 0 / 0

• css-highlight-inheritance: Regressions 1, Passing 278/ 255, Failing/Timeout 34 / 57, Skipped 11 / 11

• Percentage of NG Blocks over time, Windows 50th percentile, Stable and Dev

• Stable steady at 99.27%

• Dev steady at 99.26%
