从Tox运行Xvfb

Question

I have some code that uses gtk so unless there is an active DISPLAY , the code raises an RuntimeError: could not open display … This happens when I run tox .

Is there a way to run a Xvfb server from within tox?

I did try adding

/usr/bin/Xvfb :99 -screen 0 1280x1024x24 &

to the commands section but got an InvocationError due to the & . Without it, the command never returns and thus blocks.

Answer 1

Use xvfb-run like so:

xvfb-run tox -v --recreate

This is easily done in Jenkins Pipefiles…
