Spike/docs testing (#325)

# Description

Adds the two scripts used for testing.

Also increase a timeout because the test failed in azure. Example loading is really slow, I think it's because the load job has no requests. I made a ticket for it #324

While I looked at it, the CPU usage of the python load process was really high, so that's why I think it might be that.
