Web Test Fail/Skipped Counts

The table below is derived from the actual test expectations for recent try bot runs: linux-blink-rel 75836, mac-11-blink-rel 6701, win10.20h2-blink-rel 3259. Counts include virtual test suites owned by the team or testing stable functionality.

All test failures:

• Linux 3432 down 91

• Mac 3727 down 2

• Win 3399 down 7

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: Regressions 4, Passing 2144 / 2144, Failing/Timeout 21 / 21, Skipped 4 / 4

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

• css-highlight-inheritance: Regressions 1, Passing 264 / 241, Failing/Timeout 37 / 60, Skipped 11 / 11

• css-modules: Regressions 0, Passing 14 / 14, Failing/Timeout 0 / 0, Skipped 0 / 0

• layout_ng_printing: Regressions 19, Passing 104 / 124, Failing/Timeout 21 / 2, Skipped 1 / 0

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

• Stable steady at 99.27%

• Dev bouncing around 99.26%
