ServiceBus

Question

How to create ServiceBusMessage in unit tests? Could you add examples for unit testing bindings other than http?

I'm getting "does not accept parameters" error when I try to create the ServiceBusMessage.

Unless I'm missing something in my code, in order to test Service Bus trigger functions, ServiceBusMessage needs to be mocked?

from unittest.mock import Mock
import azure.functions as func

def test_your_function():
    mock_msg = Mock(spec=func.ServiceBusMessage)
    mock_msg.get_body.return_value = b"Your mock message body"

    # Call your Azure function
    result = your_function(mock_msg)

I'm wondering why HTTP Request has constructor but ServiceBusMessage doesn't?
