Automation and CI: How do I create a continuous integration system for network automation?

So I have been getting deeper and deeper into network automation using python, and one of the things that I am reading is the concept of continuous integration. That is using automated platforms that run tests on your code to ensure they produce the expected results. My question is, is there any way to perform automated unit tests on code who's function is to log in to network services and perform certain configuration tasks?

In particular, I'm working with Solarwinds IPAM API, Cisco NGFW, and Cisco ACI.
