need unit test without any graphical user interface

[SebG-js]

Is your feature request related to a problem? Please describe. I have integrated my teams bot to a python fast api.

Describe the solution you'd like I would like to define unit tests (pytest) to test "api/messages" when an user posts a new text message, without any graphical user interface, with a simple method, without any connection to an external server. The target is to test my code in a cicd pipeline, without any human action.

Describe alternatives you've considered How to deactivate the authentification ?
