如何检查wkwebview是否在UItest中加载完毕

import XCTest
import WebKit

class MyUITest: XCTestCase, WKNavigationDelegate {
    var webView: WKWebView!
    
    override func setUp() {
        super.setUp()
        
        let configuration = WKWebViewConfiguration()
        webView = WKWebView(frame: .zero, configuration: configuration)
        webView.navigationDelegate = self
    }
    
    func testWebViewLoading() {
        let url = URL(string: "https://www.example.com")
        let request = URLRequest(url: url!)
        webView.load(request)
        
        // 等待加载完成
        let expectation = XCTestExpectation(description: "WebView loaded")
        wait(for: [expectation], timeout: 10.0)
    }
    
    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        if !webView.isLoading {
            // 加载完成
            XCTFail("WebView not loaded")
        }
        
        // 加载完成，满足期望
        expectation.fulfill()
    }
}
