如何让Selenium 2.0等待页面加载?


当前回答

最简单的方法就是等待一些元素出现在加载页面上。

如果你想在页面加载后点击一些按钮,你可以使用等待,然后点击:

await().until().at.most(20, TimeUnit.Seconds).some_element.isDisplayed(); // or another condition
getDriver().find(some_element).click;

使用类WebDriverWait

也可以看这里

您可以期望显示一些元素。类似于c#:

WebDriver _driver = new WebDriver();
WebDriverWait _wait = new WebDriverWait(_driver, new TimeSpan(0, 1, 0));

_wait.Until(d => d.FindElement(By.Id("Id_Your_UIElement")));

在python中,你可以简单地使用:

driver.implicitly_wait(30)

Imran对Java 7的回答是:

    WebDriverWait wait = new WebDriverWait(driver, 30);

    wait.until(new ExpectedCondition<Boolean>() {
        public Boolean apply(WebDriver wdriver) {
            return ((JavascriptExecutor) driver).executeScript(
                "return document.readyState"
            ).equals("complete");
        }
    });

The best way to wait for page loads when using the Java bindings for WebDriver is to use the Page Object design pattern with PageFactory. This allows you to utilize the AjaxElementLocatorFactory which to put it simply acts as a global wait for all of your elements. It has limitations on elements such as drop-boxes or complex javascript transitions but it will drastically reduce the amount of code needed and speed up test times. A good example can be found in this blogpost. Basic understanding of Core Java is assumed.

你可以使用下面的代码片段来加载页面:

    IWait wait = new OpenQA.Selenium.Support.UI.WebDriverWait(driver,TimeSpan.FromSeconds(30.00));
    wait.Until(driver1 => ((IJavaScriptExecutor)driver).ExecuteScript("return document.readyState").Equals("complete"));

或者你可以使用waiter的任何元素被加载,并成为可见/可点击的页面上,最有可能的是,这将是在加载结束时加载,如:

    Wait.Until(ExpectedConditions.ElementToBeClickable(By.XPath(xpathOfElement));
    var element = GlobalDriver.FindElement(By.XPath(xpathOfElement));
    var isSucceededed = element != null;
