C# 如何在C中实现ExpectedConditions.AlertIsPresent
如果在所需等待期内未找到警报,WebDriverWait将引发WebDriverTimeoutException异常 在WebDriverWait周围使用try catch块捕获WebDriverTimeoutException 我使用如下扩展方法:C# 如何在C中实现ExpectedConditions.AlertIsPresent,c#,selenium,selenium-webdriver,C#,Selenium,Selenium Webdriver,如果在所需等待期内未找到警报,WebDriverWait将引发WebDriverTimeoutException异常 在WebDriverWait周围使用try catch块捕获WebDriverTimeoutException 我使用如下扩展方法: new WebDriverWait(Driver, TimeSpan.FromSeconds(5)) { Message = "Waiting for alert to appear" }.Until(d => MyExpectedCondi

try
