ResultUI is an attempt to rethink the Milo build page, with a focus on test results served from the new ResultDB backend. It aims to provide Chrome developers a convenient way to view the output of failing tests.
See the contribution guide.
If a test shares a common prefix with the previous test, the common prefix is greyed out. This makes it easier to scan through a long list of tests.
Due to a technical limitation, newly loaded test results are inserted into the list instead of appended to the end of the list. With the default filter setting, all of the tests should be loaded in the first page most of the time. So this will be less of an issue.
There's a feedback button in the top right corner of the page. It will take you to Monorail with a pre-populated template. Feedback is always welcomed :)
