I have recently used it to simulate a network breakdown between application and the database server to study what the application does. There are various clients you can use with toxiproxy via which you can set "toxics" (i.e. a delay in the network traffic, etc), but I found the cli more suited to my needs. The other clients, (for e.g. nodejs) can help you write unit tests which are meant to test the resiliency.

The other fact that caught my interest was the concept of "gamedays". It really about introducing "problems" in the production system randomly and keeping the support staff that manage application incidents on it toes. (More about in this talk: https://www.youtube.com/watch?v=TTfWpHuCJXk)
