Testing other systems using custom clients

Locust was built with HTTP as its main target. However, it can easily be extended to load test any request/response based system, by writing a custom client that triggers :py:attr:`request_success <>` and :py:attr:`request_failure <>` events.

Sample XML-RPC Locust client

Here is an example of a Locust class, XmlRpcLocust, which provides an XML-RPC client, XmlRpcClient, and tracks all requests made:

If you've written Locust tests before, you'll recognize the class called ApiUser which is a normal Locust class that has a TaskSet class with tasks in its task_set attribute. However, the ApiUser inherits from XmlRpcLocust that you can see right above ApiUser. The XmlRpcLocust class provides an instance of XmlRpcClient under the client attribute. The XmlRpcClient is a wrapper around the standard library's :py:class:`xmlrpclib.ServerProxy`. It basically just proxies the function calls, but with the important addition of firing :py:attr:`` and :py:attr:`` events, which will make all calls reported in Locust's statistics.

Here's an implementation of an XML-RPC server that would work as a server for the code above:
