…st suite The subtests in the tests were running in parallel without any kind of synchronization. There was therefore no guarantee about the order the PASS lines would be printed in. This led to flakiness in the WebKit test suite: https://bugs.webkit.org/show_bug.cgi?id=224377. To address the issue, we now run subtests one after another, in a well-defined order.

I assume https://bugs.webkit.org/show_bug.cgi?id=223966 was the intended WebKit bug. With audit.js uses |
Yes, sorry about that.
Yes, I do believe the issue was specific to this test (or a few tests). This is not the first time I have to fix webaudio tests to get reliable ordering: see dfd29f2. |
Sorry about that. Since Chrome doesn't use expected files anymore (except when needed), I didn't notice that the order could change. All the tests pass, so the order didn't matter. |
