Web Test Regressions and Status Changes

When triaging newly added tests, be sure to add necessary information to crbug.com and update the metadata at wpt.fyi.

Test Status Changes, maybe incorrect due to Windows failed test shard:

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 58 / 58, Failing/Timeout 0 / 0, Skipped 0 / 0

• css-highlight-inheritance: Regressions 1, Passing 286/ 262, Failing/Timeout 34 / 58, Skipped 11 / 11

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

• The metric has overflowed 100%
  

• I will stop tracking. Is there a new metric?

Metrics

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

• Style metrics went up then down

• Some layout metrics moved too.
