Web Test Fail/Skipped Counts

The table below is derived from the actual test expectations for recent try bot runs: linux-blink-rel 78258, mac-11-blink-rel 7063, win10.20h2-blink-rel 3598. Counts include virtual test suites owned by the team or testing stable functionality.

All test failures:

• Linux 3237 up 25

• Mac 3450 up 11

• Win 3199 up 24

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: Virtual suite is now skipped

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

• css-highlight-inheritance: Regressions 1, Passing 274/ 251, Failing/Timeout 34 / 57, Skipped 11 / 11

• layout_ng_printing: Regressions 25, Passing 98 / 124, Failing/Timeout 27 / 2, Skipped 1 / 0

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

• Stable steady at 99.27%

• Dev steady at 99.27%
