[Feature]: Add timeout parameter to create_app_fixture

[evanglass]

Category

Testing

Scope

Minor Enhancement

Problem

Currently, apps which take too long to start up (e.g. apps which load large data objects on startup or use packages like rpy2) can fail with the message "TimeoutError: Timeout while waiting for Shiny app to become ready". This is due to the timeout duration being hardcoded to just 30 seconds.

Solution

The feature would add a timeout_secs parameter like that in run_shiny_app. This parameter would be passed into the shiny_app_gen calls.

def test_app_code(page: Page, app: ShinyAppProc):

    page.goto(app.url)
    # Add test code here
