Testing

Helper methods for testing workflows.

pyapp_flow.testing.call_node(node: Callable[[WorkflowContext], Any], **context_vars: Any) → WorkflowContext

Simplifies the testing of any node.

Handles the boilerplate code required to set up a pyapp_flow.WorkflowContext with the expected variables.

Method returns the generated context object to be asserted on.

def test_find_isbn__with_known_title():

    context = call_node(find_isbn, title="Hyperion")
    actual = context.state["isbn_13"]

    assert actual == "978-0553283686"
