[V2] cargo test STATUS_ENTRYPOINT_NOT_FOUND error.

[probaku1234]

I'm trying to implement unit testing for tauri command function.
When I run this test, It fails with the STATUS_ENTRYPOINT_NOT_FOUND error.

    use tauri::test::{mock_builder};

    fn create_app<R: tauri::Runtime>(builder: tauri::Builder<R>) -> tauri::App<R> {
        builder
            // .invoke_handler(tauri::generate_handler![ping])
            // remove the string argument to use your app's config file
            .build(tauri::generate_context!("tauri.conf.json"))
            .expect("failed to build app")
    }
    

    #[test]
    fn test_greet() {
        let app = create_app(mock_builder());
    }

The original code is from the example code of the link.
I commented out most of the code to find which code causes the error, and It seems builder: tauri::Builder<R> is the one.
Any idea how to fix this issue?

We have a workaround for our repo here

I tried to fix this in the tauri crate itself but didn't find a way to, unfortunately.
