I'm really glad it worked for you - this was why I created AxRuntime in the first place - to help other developers. I actually did not foresee it being used to CI - but now it seems like an obious use case. I also added an enhancement for future to be able to run it "headless" (without need for fake X).
I think you mentioned that you want to also write a post on how to achieve CI for other. If you do so, let me know
