[Development] How to track down CI problems

[Bernd Lamecker]

Hi,

i tried to find the reason why https://codereview.qt-project.org/#/c/91748/ CI fails. 
I set up a Windows 7-x86 in a VM using MSVC2010SP1 and compiled Qt 5.4 and QtWebChannel and the test are passing. But off course i have not the complete environment from the CI. 
Is it possible to trigger CI runs for specific environments only? I'm not even sure if the linux versions were finished and passing, because CI seems to stop all runs as soon as one failed.  
Other ideas on how to find the issue?

Regards,
Bernd
