CSS Locator with contains（）使用Selenium WebDriver的InvalidSelectorException [英] CSS Locator with contains() InvalidSelectorException using Selenium WebDriver

问题描述

我正在学习 Selenium Webdriver 并尝试编写一个简单的测试脚本。

I am learning Selenium Webdriver and trying to write a simple test script.

目的是获取 Gmail <上的关于Google 链接/ strong>页面以便练习 CSS定位器 。

The intent is to get the About Google link on Gmail page so as to practice CSS locators.

以下是代码：

Here is the code:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class GoogleSearch {

    public static void main(String[] args) {            
        WebDriver driver = new FirefoxDriver();         
        driver.get("https://www.gmail.com");

        WebElement aboutGoogle = driver.findElement(By.cssSelector("a:contains('About Google')"));          

        driver.close();
        driver.quit();          
    }    
}

我得到以下提到的例外：

I get the below mentioned exception:

Exception in thread "main" org.openqa.selenium.InvalidSelectorException: The given selector a:contains('About Google') is either invalid or does not result in a WebElement. The following error occurred:
InvalidSelectorError: An invalid or illegal selector was specified

我已经检查过并且能够在Selenium中找到该元素IDE使用相同的定位器。

I had checked and was able to find the element in Selenium IDE using the same locator.

我在某处读到 findElement（）方法返回一个DOM节点，代码期待一个WebElement对象。

I read somewhere that the findElement() method is returning a DOM node and the code is expecting a WebElement object.

如果是这种情况那么，是否有解决方法/投射？

If this is the case then, is there a workaround/casting?

有任何建议吗？

推荐答案

包含文本的CssSelector在脚本中不起作用，但它在selenium IDE中有效。

CssSelector with contains text does not work in scripting but it works in selenium IDE.

还有一个是，在gmail这样的网站上工作并不好..你可以通过使用 http：// seleniumtrainer中的组件来学习.COM / 。它有利于启动。

One more is, its not good to work on sites like gmail.. you can learn by using components in http://seleniumtrainer.com/. its good for start up.

谢谢
