Thanks Julian! Less worried about the test, I can deal with the windows. More concerned about headless as you indicated. I guess this challenge is a bit different than usual. There is no expected output that can be measured and scored, but it is more of an open challenge and graphical presentation of the results. I assume there is going to be more reliance on human going over the notebook rather than automated tests. So, maybe it is not an issue at all. Am I correct?
thank you!
