如何使用Xamarin.UI测试将屏幕上的文本保存为字符串？

using NUnit.Framework;
using Xamarin.UITest;

namespace YourNamespace
{
    [TestFixture(Platform.Android)]
    [TestFixture(Platform.iOS)]
    public class YourTestClass
    {
        IApp app;
        Platform platform;

        public YourTestClass(Platform platform)
        {
            this.platform = platform;
        }

        [SetUp]
        public void BeforeEachTest()
        {
            app = AppInitializer.StartApp(platform);
        }

        [Test]
        public void SaveTextAsString()
        {
            // 定位文本元素
            var textElement = app.Query(c => c.Marked("yourTextElementId")).FirstOrDefault();

            // 获取文本内容
            string text = textElement?.Text;

            // 将文本保存为字符串
            string savedText = text ?? string.Empty;

            // 打印保存的文本
            System.Console.WriteLine("Saved Text: " + savedText);

            // 进行断言或其他操作
            Assert.IsNotNull(savedText);
        }
    }
}
