Here's an example locustfile.py, which defines a simple user behavior which consists of a single "task" which gets a specific webpage: Usage; Here we will be testing a non-restful service, for example, some python functions. It also specifies the website address that we test (--host), which is the port 3000 at http://localhost in our example. Sample XML-RPC User client; Extending Locust using event hooks.
