Test output loading improvements

We've improved the test output and ad-hoc run experiences, focusing on performance.

Kicking off an ad-hoc run and getting to the test output page is now faster than before. You'll spend less time waiting, and less time looking at loading spinners.

Test output loading experience

The loading experience for the results of a test that is still running has been improved, and streamlined.

You'll now see a checklist that tells you what mabl is doing behind the scenes while getting your test ready.

As soon as you test has started running, you'll see the steps start coming in as usual.

Ad-hoc run panel improvements

Previously, it took awhile to start a new ad-hoc test run and get to the live output for that run.

When you start an ad-hoc run, its test output page is now available right away. You can click the link as soon as you kick off the test run.
