Headless integration tests of an eclipse plugin with maven tycho

Question

I wrote some Junit tests for my eclipse plugin. If I start my test suite as a "JUnit Plug-in Test" from Eclipse, everything is working fine. Now I want to run them from Maven Tycho.

So I put the following packaging : "eclipse-test-plugin", in the pom.xml and the integration tests start with a "mvn clean integration-test". So I think my maven configuration is quite OK.

But some tests are failing, and I suspect the headless build can't detect the IMarkers my tests are trying to detect, since IMarkers are UI components.

Am I right? Any idea to get my tests based on IMarkers running with Tycho?
