pytest-jubilant-bdd

A pytest plugin providing reusable Gherkin step handlers for behavior-driven testing of Juju charmed operators.

pytest-jubilant-bdd is a collection of various utilities that make it easier for you and your friends to write behavior-driven tests for Juju charmed operators. The plugin provides a curated set of reusable Gherkin step handlers built on top of jubilant and pytest-bdd, so you can focus on the behavior of your charms instead of the boilerplate of driving the Juju lifecycle from your tests. Current reusable steps shipped in the pytest-jubilant-bdd package include:

• add_model: A given step handler for adding a new Juju model to the testing context.
• add_unit: A given step handler for adding units to a deployed application.
• deploy: A given step handler for deploying a charm from Charmhub.
• deploy_local: A given step handler for deploying a local .charm file onto a Juju model.
• integrate: A given step handler for integrating two Juju applications.
• model_exists: A given step handler for asserting that a Juju model currently exists.
• is_integrated: A given step handler for asserting that two applications are currently integrated.
• is_deployed: A given step handler for asserting that an application is currently deployed on a Juju model.
• run_action: A when step handler for running a Juju action on one or more units.
• run_exec: A when step handler for executing a command on one or more machines or units.
• assert_all_agent_status: A then step handler for asserting the status of all agents in one or more models.
• assert_workload_status: A then step handler for asserting the workload status of a deployed application.
• assert_workload_status_message: A then step handler for asserting the message attached to a workload status.
