java - 如何使用 Selenium/Java 验证页面中元素的存在

Question

我正在尝试找出一种方法来查看页面上是否存在元素。

这就是我到目前为止所拥有的。

但是，如果元素不存在，则会抛出异常，并且脚本将停止。

有人可以帮我找到更好的方法吗？

//Checking navbar links
        System.out.println("=======================");
        System.out.println("Navbar link checks");
    //Checking for Web link element in Nav bar
        if(driver.findElement(By.xpath("/html/body/div[2]/div[1]/div[1]/ul/li[1]/a"))!= null){
            System.out.println("Web link in Navbar is Present");
            }else{
            System.out.println("Web link in Navbar is Absent");
            }
    //Checking for Images link element in Nav bar
        if(driver.findElement(By.xpath("/html/body/div[2]/div[1]/div[1]/ul/li[2]/a"))!= null){
            System.out.println("Images link in Navbar is Present");
            }else{
            System.out.println("Images link in Navbar is Absent");
            }
    //Checking for News link element in Nav bar
        if(driver.findElement(By.xpath("/html/body/div[2]/div[1]/div[1]/ul/li[3]/a"))!= null){
            System.out.println("News link in Navbar is Present");
            }else{
            System.out.println("News link in Navbar is Absent");
            }
    //Checking for Videos link element in Nav bar
        if(driver.findElement(By.xpath("/html/body/div[2]/div[1]/div[1]/ul/li[4]/a"))!= null){
            System.out.println("Videos link in Navbar is Present");
            }else{
            System.out.println("News link in Navbar is Absent");
            }
    //Checking for Maps link element in Nav bar
           if(driver.findElement(By.xpath("/html/body/div[2]/div[1]/div[1]/ul/li[5]/a"))!= null){
            System.out.println("Maps link in Navbar is Present");
            }else{
            System.out.println("Maps link in Navbar is Absent");
            }

您可以使用几种不同的方法。为此，我可能建议使用 findElements:

if(driver.findElements(By.xpath("/html/body/div[2]/div[1]/div[1]/ul/li[1]/a"))!= 0)
