• Shard Balancing. Test runners can now fetch each test’s predicted duration from a new Durations API and split the suite into shards of roughly equal running time, so a run finishes sooner instead of waiting on its slowest shard. See Balancing Playwright Test Shards for how it works and its tradeoffs.

  Playwright Test is the first test runner to support it; see its documentation for setup. More runners are coming.
