GPUI with UI Unit Test

Hi, I'm interested in GPUI crate, I'm wondering if we have any method to perform UI Unit Test to check the correctness of code utilized GPUI. Just Like Jest+React-Testing-Library for Javascript or Xcode UI Unit test for Swift.

Eg:

1. Snapshot Test: Giving certain State, dump the UI to xml/html, then check the xml content matches certain snapshot string.
2. Reaction Test: Giving certain State, dispatch certain action on certain element, then check if desired reaction/action were trigged.

GPUI does have the macro gpui::test which allows you to simulate keystrokes, change state, and more. I think this is what you are looking for.

You can see it documented here https://github.com/zed-industries/zed/blob/main/crates/gpui_macros/src/gpui_macros.rs#L85C1
