- Daily test history. Test history can now be bucketed by day instead of by
commit, with each bar standing for a whole day. A test’s flip rate, fail rate, and
duration trend are then computed over days rather than commits, so sorting by flip
rate or fail rate gives a long-term view of test performance instead of
commit-to-commit, which might be noisy. Pick the default for a project in its
settings (By commit or By day) and override it per view from the selector on
the History column header; the
flakinessCLI takes the same--history commit|dayflag onlist tests.
