我遇到了一个问题.我的网页有一个DropDownList控件. DropDownList值更改后(通过选择其他值),页面将刷新并呈现内容.
I have run into a problem. My web page has a DropDownList control. Once the DropDownList value changes (by selecting a different value), the page refreshes and it renders the contents.
然后我必须先使用Thread.Sleep(2000);和FindElement.
我的问题:等待网页加载的最佳方法是什么?
My question: What is the best way to wait till the page loads?
我的代码中有很多Thread.Sleep(2000)实例,我开始认为这不是解决问题的最佳方法.
I have so many instances of Thread.Sleep(2000) in my code that I am beginning to think this is not the best way to approach the problem.
这是我的代码:
[TestInitialize()] public void Setup() { if (BaseIntegrationTest.browserType.Equals(BaseIntegrationTest.IE)) { driver = new InternetExplorerDriver(); } else if (BaseIntegrationTest.browserType.Equals(BaseIntegrationTest.CHROME)) { //driver = new ChromeDriver(); } else if (BaseIntegrationTest.browserType.Equals(BaseIntegrationTest.FIREFOX)) { driver = new FirefoxDriver(); } }第二部分:
[TestMethod] public void testVerifyData() { // ................... // ................... driver.FindElement(By.XPath("//*[@id='ctl00_NavigationControl1_lnke']")).Click(); Thread.Sleep(2000); //select from the dropdownlist. IWebElement catagory = driver.FindElement(By.Id("ctl00_ContentPlaceHolder1_Filter")); SelectElement selectCatagory = new SelectElement(catagory); selectCatagory.SelectByText("Employee"); Thread.Sleep(2000); // ................... // ................... }推荐答案
Thread.Sleep()是一种非常不鼓励执行等待的方法
Thread.Sleep() is a very discouraged way to implement your waits
硒代码 seleniumhq/docs/04_webdriver_advanced.html
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10)); IWebElement category = wait.Until<IWebElement>((d) => { return d.FindElement(By.Id("ctl00_ContentPlaceHolder1_Filter")); });这是一个显式等待的示例,其中硒在找到您的元素之前不会执行任何操作
That is an example of an explicit wait where selenium will not execute any actions until your element is found
隐式等待的示例是:
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10)); IWebElement category = driver.FindElement(By.Id("ctl00_ContentPlaceHolder1_Filter"));在隐式等待中,驱动程序将等待给定的时间,并在DOM中轮询不存在的任何元素.
In implicit waits the driver will wait for a given amount of time and poll the DOM for any elements that do not exist.
编辑
public WaitForElement(string el_id) { WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10)); IWebElement category = wait.Until<IWebElement>((d) => { return d.FindElement(By.Id(el_id)); }); }更多推荐
使用Webdriver使用Selenium进行超时的最佳方法是什么
