Question

我正在使用最新的Chrome和Webdriver 2.33，并且我遇到了IgnoreExceptionTypes的一些问题。在下面的代码中，webdriver会像我期望的那样等待，但它实际上不会忽略异常：

WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(8));
wait.IgnoreExceptionTypes(
    typeof(WebDriverTimeoutException),
    typeof(NoSuchElementException)
);  
wait.Until(ExpectedConditions.ElementIsVisible(By.XPath(firstResultX)));

代码在try / catch中，我尝试将它移到try / catch之外并收到同样的问题。我不知道从哪里开始，任何帮助都将不胜感激。

Answer 1

您可以使用FluentWaits。

Wait<WebDriver> wait = new FluentWait<WebDriver>(getDriverInstance())
                .withTimeout(timeoutSeconds, TimeUnit.SECONDS)
                .pollingEvery(sleepMilliSeconds, TimeUnit.SECONDS)
                .ignoring(NoSuchElementException.class);

wait.until(<Your expected condition clause.>);

如果这不能解决您的问题，请告诉我。

对于 C#，不同的等待是 -

      ` //Implicit Wait - Once set it remains till the life of the session
        Driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);

        //Explicit Wait - Polling interval is 250ms
        //using OpenQA.Selenium.Support.UI; 
        WebDriverWait wait = new WebDriverWait(Driver, TimeSpan.FromSeconds(30));
        //this wait utility ignores no such element errors by default
        IWebElement webElement = wait.Until(e => e.FindElement(By.Id("value")));

        //Fluent wait - Polling interval is set by us
        WebDriverWait fluentWait = new WebDriverWait(Driver, TimeSpan.FromSeconds(30))
        {
            PollingInterval = TimeSpan.FromSeconds(2)
        };
        fluentWait.IgnoreExceptionTypes(typeof(AccessViolationException), typeof(NoSuchElementException));
        IWebElement element = wait.Until(e => e.FindElement(By.Id("value")));`

WebDriverWait不会忽略异常
