Web Test Fail/Skipped Counts

The table below is derived from the actual test expectations for recent try bot runs: linux-blink-rel 77188, mac-11-blink-rel 6889, win10.20h2-blink-rel 3448. Counts include virtual test suites owned by the team or testing stable functionality.

All test failures:

• Linux 3384 down 8

• Mac 3684 unchanged

• Win 3343 down 8

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 2143 / 2144, Failing/Timeout 23 / 22, Skipped 4 / 4

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

• css-highlight-inheritance: Regressions 1, Passing 272 / 249, Failing/Timeout 34 / 57, Skipped 11 / 11

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

• 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 is noisy but maybe aligned with Stable now at 99.27%

Metrics

Reminder to add any performance wins to go/wp-perfy.
