Response class

This class actually resides in the requests <https://requests.readthedocs.io/>_ library, since that's what Locust is using to make HTTP requests, but it's included in the API docs for locust since it's so central when writing locust load tests. You can also look at the :py:class:Response <requests.Response> class at the requests documentation <https://requests.readthedocs.io/>_.

.. autoclass:: requests.Response :inherited-members: :noindex:

ResponseContextManager class

.. autoclass:: locust.clients.ResponseContextManager :members: success, failure

.. _exceptions:

Exceptions

.. autoexception:: locust.exception.InterruptTaskSet

.. autoexception:: locust.exception.RescheduleTask

.. autoexception:: locust.exception.RescheduleTaskImmediately

Environment class

.. autoclass:: locust.env.Environment :members:

.. _events:

Event hooks

Locust provides event hooks that can be used to extend Locust in various ways.

The following event hooks are available under :py:attr:Environment.events <locust.env.Environment.events>, and there's also a reference to these events under locust.events that can be used at the module level of locust scripts (since the Environment instance hasn't been created when the locustfile is imported).

.. autoclass:: locust.event.Events :members:

.. note::

It's highly recommended that you add a wildcard keyword argument in your event listeners
to prevent your code from breaking if new arguments are added in a future version.

EventHook class

The event hooks are instances of the locust.events.EventHook class:

.. autoclass:: locust.event.EventHook :members:

Runner classes

.. autoclass:: locust.runners.Runner :members: start, stop, quit, user_count

.. autoclass:: locust.runners.LocalRunner

.. autoclass:: locust.runners.MasterRunner :members: register_message, send_message

.. autoclass:: locust.runners.WorkerRunner :members: register_message, send_message, client_id, worker_index

Web UI class

.. autoclass:: locust.web.WebUI :members:
