如何断言动态图像不存在于 Selenium Python Web 驱动程序的网页中

Question

There is webpage that loads 4 images dynamically. They cannot be clicked and in the source code there is only src attribute. Using XPath I found the URL for each image. How do I find if a particular image is present or not on page load? I need this in Selenium Python web driver.

Below is the code which I need to automate:

<div class="row">
<div id="1" class="xx">
    <div class="row">
        <div class="yy"> <img src="/img/images/pic-1.jpg"> </div>
        <div class="a"> hello 1 </div>
    </div>
    <br>
    <br>
    <div class="row">
        <div class="yy"> <img src="/img/images/pic-2.jpg"> </div>
        <div class="a"> Hello 2 </div>
    </div>
    <br>
    <br>
    <div class="row">
        <div class="yy"> <img src="/img/images/pic-3.jpg"> </div>
        <div class="a"> Hello 3 </div>
    </div>
</div>
</div>

The image keeps changing every time the page is loaded. I need to find if pic-1.jpg is present/displayed when the page is loaded.

I don't know python but since you don't have any other answers I'll try to help you with some Java code that hopefully you can translate.

You basically want to grab all the IMG tags inside a DIV with class yy . You then loop through that collection of elements looking for the desired picture name in the src string. If it is found, the element HTML is printed.

List<WebElement> images = driver.findElements(By.cssSelector("div.yy > img"));
String imageFileName = "pic-1.jpg";
for (WebElement image : images)
{
    if (image.getAttribute("src").contains(imageFileName))
    {
        System.out.println(image.getAttribute("innerHTML"));
    }
}
