@MarcinVaadin do you remember how multithreading can be customised in TestBench, I recall we added a chapter about in for JUnit 5, but I couldn't quickly find it.

I also recall we put multithreading config like here https://github.com/vaadin/testbench/blob/a645fddcaf19ff161f4cf4bedfe0e081709a429c/vaadin-testbench-integration-tests-junit5/src/test/resources/junit-platform.properties , but this is not in the main branch for some reason.

Here it is https://github.com/vaadin/testbench/blob/main/vaadin-testbench-core-junit5/src/main/resources/junit-platform.properties

Closed, because of no answer since Oct 14, please provide more information for us to reproduce and re-open the issue.

@knoobie we have a solution [here](https://github.com/vaadin/flow/pull/14788) and currently making a test coverage for it, but the main obstacle for us is that with Jetty we got `ws-disconnect-on-heartbeat` errors, not clear...

Fixed in https://github.com/vaadin/flow/releases/tag/23.3.0.rc1 and will be included into next Vaadin 23.3 release. `/VAADIN/push` mapping is now used always for push requests.

Closed in favour of https://github.com/vaadin/flow/pull/15188
