Attachment: Bug 1667278 - [1.0] Remove the strict count contraint for the number of onMetadata calls to reduce non-critical test failure noise.

Comment 7

[Eugen Sawin [:esawin]]

The test fails because there are 2 instead of 1 calls to onMetadata on the second session for the given test steps.

Calling onMetadata more than once is not critical here since we don't give any guarantees in the API on the number of calls and the provided metadata remains correct.
For this reason, I'm going to remove that constraint in the test for now to reduce intermittent failure noise.

@alwu, do you have an idea, why that might be happening in this case?

Comment 9

[Alastor Wu [:alwu]]

I suppose the code is running from here [1]? If that is the loaded page for sessions, then we do dispatch two times of metadatachange event.

The first one is resulted in calling active.play() where we haven't set the media session metadata, so we would use the default metadata in the beginning. Then, when calling updateMetadata(), it would update the metadata via MediaSession API, which would update the current metadata to the customize metadata, and dispatch the second metadatachange event.
