如果页面异步更改其内容（不重新加载页面），如何制作WebDriverWait？

Question

我正在使用Selenium Webdriver（Java）进行编码测试，获得https://cloud.google.com作为驱动程序。我首先查找搜索输入字段sendKeys（“搜索短语\ n”）。在该页面开始更改其内容之后，我尝试使用WebDriverWait进行这些更改：

    // first Wait - is to wait before page starts changing is content by removing search google icon
            new WebDriverWait(driver, 30).until(ExpectedConditions.invisibilityOf(searchInputFieldIcon));
    //second Wait  - i'm waiting new hyperlink to appear (this hyperlink appears in search results after the whole page is asynchronically reloaded without page reloading)            
            new WebDriverWait(driver,30)
        .until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//a[@href='https://cloud.google.com/products/calculator']")));

关键是，等待不会在元素显示之前等待30秒。代码只会引发异常：

    org.openqa.selenium.NoSuchElementException:
 no such element: Unable to locate element: {"method":"xpath","selector":"//a[@href='https:`//cloud.google.com/products/calculator']"}`

任何帮助将不胜感激！

Answer 1

Inspect Element

请检查所附的屏幕截图。这里的Href链接不同于您在代码中使用的链接。

您可以使用下面的代码

wait.until(expectedConditions.visibilityOfElementLocated(By.linkText("Google Cloud Platform Pricing ")));
