I’ve worked with clients in the past who want to do a better job of testing 
z/OS as a platform, but don’t know where to start.  So I’ve released a tool to 
give system programmers, site reliability engineers, or anyone else who wants 
to test z/OS at a system level a place to start:  the Chaos Toolkit Extension 
for z/OS.  The Chaos Toolkit (https://chaostoolkit.org) is a cross-platform 
test orchestration/automation platform, but it requires extensions for each 
platform it wants to interact with.  So I’ve written an extension for z/OS 
(https://pypi.org/project/chaostoolkit-zos/).  There’s a quick demo here:  
https://youtu.be/v-6xvAeH0p0.

I do want to emphasize that the extension is in its infancy, and between 
COVID-19 and two small children, it’s taken me a lot longer than I’d planned to 
release this.  But my intention is that, over time, to get the toolkit to a 
point where you can easily do the same sort of basic testing that I do when I’m 
doing initial bringup testing of a new release of z/OS, so when you make 
changes to your applications, you can validate in your test environment that 
things still work, and your applications can tolerate failures when they do 
happen.

If you’ve got any questions, suggestions, complaints, or whatever, feel free to 
reply here or contact me off-list; I’ll help as best I can.
