如何在SwiftUI的UI测试中获取环境对象/发布器

class AppEnvironment: ObservableObject {
    // 环境对象的属性和方法
}

@main
struct MyApp: App {
    @StateObject private var appEnvironment = AppEnvironment()

    var body: some Scene {
        WindowGroup {
            ContentView()
                .environmentObject(appEnvironment)
        }
    }
}

import XCTest

class MyUITests: XCTestCase {
    var app: XCUIApplication!

    override func setUp() {
        super.setUp()
        app = XCUIApplication()
        app.launchArguments.append("--uitesting")
        
        // 创建环境对象并设置为应用程序的根视图的环境对象
        let appEnvironment = AppEnvironment()
        appEnvironment.someProperty = "Some value"
        app.environmentObjects[AppEnvironment.self] = appEnvironment
        
        app.launch()
    }

    func testExample() throws {
        // 在测试中获取环境对象
        let appEnvironment = app.environmentObjects[AppEnvironment.self] as! AppEnvironment
        XCTAssertEqual(appEnvironment.someProperty, "Some value")
        
        // 进行其他测试操作
    }
}
