During my last adventures with Jenkins y suffered into a new problem trying to running my gtester’s test battery.
[exec] TEST: tests/stkmngtest... (pid=13754) [exec] [exec] Gtk-WARNING **: cannot open display: [exec] aborting... [exec] FAIL: tests/stkmngtest
that makes my test suite were aborted and also makes Jenkins useless, and useless things are my competitors because the only useless thing allowed at home is me 😛 .
The basic problem is that there no are a XOrg session running, first I change runlevel to 5 and expect see test runing a big FAIL was the result.
after reading a bit of literature I discover a thing called Xvfb
for install follow these steps
yum install Xvfb
yum install mesa-dri-drivers
the next step was try to install Xvfb plugin in jenkins but i doesn’t work it give these exception
FATAL: null java.lang.NullPointerException at org.jenkinsci.plugins.xvfb.XvfbBuildWrapper.decorateLauncher(XvfbBuildWrapper.java:165) at hudson.model.AbstractBuild$AbstractRunner.createLauncher(AbstractBuild.java:525) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:452) at hudson.model.Run.run(Run.java:1434) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:239)
I found a quick and dirty solution that is put a xvfb-run call in commands that need a xserver like this <target name=”runtest” description=”run glib test”>
the solution for solve these problem is configure Jenkins plugin BIG BIG BIG THANKS TO Tomasz Wysocki, he show me the missing configuration options.
Here for global settings
