[platform-releng-dev] Official tests vs Maven tests

[Mickael Istria <mistria@xxxxxxxxxx>]

Hi all,

With https://bugs.eclipse.org/bugs/show_bug.cgi?id=541415 , it appeared that there can be major divergence between what we can see when running tests locally, on Gerrit and in the "official" tests.

It seems for example that programatically generated SWT events can be ignored on official test execution when they work fine locally or on CI.

Does anyone have a clue or why this happens and how we can remediate?

I may have one, that I experience locally: I'm using Xephyr and mutter (a bit different from what's used on Jenkins, but still it's a similar stack), and I see the one of them seems to have an energy saving strategy that makes that after some time, screen turns black, and when this happens, some tests do fail.

Could it be also something that happen when running the big test suite?

Cheers,
