PerfSONAR is a network measurement toolkit collection for testing and sharing data on end-to-end network perfomance. The overall benefit of using network measurement tools like PerfSONAR is they can find issues before they become a large elephant in the room that nobody wants to talk about. Specifically, with the right answers from the right tools, patching can become more stringent, network traffic can be shaped to speed connections across the board, and the network infrastructure design can be improved.

pytest turns out to be easy to use, easy to work with and easy to integrate into my work. Part of the reason for this is that pytest abandons the Python idea of "there's only one way to do it", giving developers a great degree of flexibility and freedom in choosing how to write tests.
