How can we make an automated test for this?

Just auto would be better. Let’s dodge the * placement issue.

> +    else if (auto *windowScene = self.window.windowScene)

Ditto.

I considered writing an API test for this that would mock out -_appAdoptsUISceneLifecycle to return YES, but I don't think such a test would be very useful. Generally, writing an API test for this is tricky, because TestWebKitAPI isn't even a UI application on iOS, and so the UIApplication, windows, and their window scenes would all need to be mocked by the test.

I think when we eventually convert WebKitTestRunnerApp into a scene-based UIApplication, we'll be able to get test coverage for this codepath.

Sounds good — changed to just auto.

Changed to just auto.
