java - 如何使用 Java 使用 Selenium WebDriver 验证动态图库？

Question

问题:

图库中的图像始终是动态的，但文章不断变化。当我单击文章时，图像库将打开，其中包含大图像和其他带轮播的缩略图。

<小时/>

第一个场景:

我需要验证图像是否已加载并且图库正常。此外，还必须导航和验证其他缩略图。`

示例:

• 1. 我在文章页面上打开该文章，因此该文章页面打开了一个包含超过 5 个缩略图的图库。
• 现在我需要验证图像是否已打开，并逐个导航以验证缩略图。

<小时/>

第二个场景:

有时本文会加载图像，有时它可以有视频或只有单个图像。这就是我所说的“动态”。`

所以每次图像发生变化时，需要知道如何处理这种情况下面是html代码:

<div class="carousel royalSlider rsDefault rsAutoHeight rsHor  rsWithThumbs rsWithThumbsHor" style="min-height: 463.8px;">
    <div class="rsOverflow" style="width: 773px; height: 436px; transition:  height 600ms ease-in-out;">
        <div class="rsContainer" style="transition-duration: 600ms; transform:  translate3d(-797px, 0px, 0px); transition-timing-function: cubic-bezier(0.445,  0.05, 0.55, 0.95);">
            <div style="left: 0px;" class="rsSlide"><img class="rsImg  rsMainSlideImage"  src="http://resources.carsguide.com.au/styles/cg_hero_large/s3/lexus-rx350-2016- (1).jpg"></div>
            <div style="left: 797px;" class="rsSlide rsActiveSlide"><img  class="rsImg rsMainSlideImage"  src="http://resources.carsguide.com.au/styles/cg_hero_large/s3/lexus-rx350-2016- (2).jpg"></div>

            <div class="rsArrowIcn"></div>
        </div>
        <div class="rsArrow rsArrowRight" style="display: block;">
            <div class="rsArrowIcn"></div>

        <div class="rsGCaption">Lexus RX 350 F Sport.<noscript>&lt;img  src=http://resources.carsguide.com.au/styles/cg_hero_thumbnail/s3/lexus-rx350- 2016-(2).jpg&gt;</noscript></div>

        <div class="rsThumbsArrow rsThumbsArrowLeft  rsThumbsArrowDisabled">
            <div class="rsThumbsArrowIcn"></div>
        </div>
        <div class="rsThumbsArrow rsThumbsArrowRight rsThumbsArrowDisabled">
            <div class="rsThumbsArrowIcn"></div>
        </div>
    </div>
    <div style="clear:both; float: none;"></div>
</div>

到目前为止我所做的就是:

• 1. 打开网址。
• 点击文章页面。
• 现在打开该/任何文章。

我的第四步是在文章打开时验证该图像(带有缩略图)。我无法执行第四步。我现在没有任何错误，直到第 3 步我都能成功完成。

您好，请按照下面的方式操作

public class WorkingWithThumbNails {
    public static void main(String[] args) {
        WebDriver driver = new FirefoxDriver();
        driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
        driver.get("http://www.carsguide.com.au/car-reviews/toyota-tarago-used-review-1990-2015-41984");

    // Now count the number of images in the thumb-nails cause
    // this will decide number of clicks on the next Arrow

    List<WebElement> myThumbnails = driver.findElements(By.cssSelector(".rsTmb.lazyload"));
    List<WebElement> myMainImages = driver.findElements(By.cssSelector(".rsImg.rsMainSlideImage"));

    System.out.println("Size of the thumbnail is : " + myThumbnails.size());
    System.out.println("Size of the main image is : " + myMainImages.size());


    // print the urls of the thumb-nails as well
    for(int i=0;i< myThumbnails.size();i++){
        myThumbnails = driver.findElements(By.cssSelector(".rsTmb.lazyload"));
        System.out.println("Url for the Thumbnail is : " + myThumbnails.get(i).getAttribute("src"));

        myMainImages = driver.findElements(By.cssSelector(".rsImg.rsMainSlideImage"));
        System.out.println("Url for the main image is : " + myMainImages.get(i).getAttribute("src"));

        // now implement the logic of img verification, logic can be many but here i used if src for bigger img 
        // contains img name as per the thumbnail img name then its ok img is properly loaded and hence it is right image.

        String[] myMainImgName = myMainImages.get(i).getAttribute("src").split("s3");

        if(myThumbnails.get(i).getAttribute("src").contains(myMainImgName[1])){
            System.out.println("Main image is as per the thumbnail.");
            // to verify next thumb-nail img with main img we have to click
            // here if is because loop will run one more time then img size
            if(driver.findElements(By.xpath("//*[@class='rsArrow rsArrowRight']/div")).size() > 0){
                driver.findElement(By.xpath("//*[@class='rsArrow rsArrowRight']/div")).click();
            }
        }else{
            // apply the same logic for videos 
            // hope you can do this 
        }
    }

}

}
