Atata -如何在页面类中定义警报？

using Atata;

public class HomePage : Page<HomePage>
{
    [Alert]
    public Alert<_> SuccessAlert { get; private set; }

    [Alert(AlertType.Warning)]
    public Alert<_> WarningAlert { get; private set; }

    [Alert(AlertType.Error, Timeout = 5)]
    public Alert<_> ErrorAlert { get; private set; }
}

HomePage page = Go.To<HomePage>();

if (page.SuccessAlert.Exists())
{
    string successMessage = page.SuccessAlert.Text;
    // 处理成功警报
}

if (page.WarningAlert.Exists())
{
    string warningMessage = page.WarningAlert.Text;
    // 处理警告警报
}

if (page.ErrorAlert.Exists())
{
    string errorMessage = page.ErrorAlert.Text;
    // 处理错误警报
}
