How to run integration test for a chainlit app

[tjroamer]

I'd like to run an integration test for my chainlit app with the pytest framework with the following requirements to make sure the app is not broken:

• I want to define a test module, test_app in a tests folder
• in the test module, I first start the chainlit app
• I send a message to the app by calling a function
• I got a response message from the app and verify the response
• But I don't want to UI in the browser during the test, just want the app running in the background

Could anyone give me some ideas? Thanks in advance.
