如何使用Java使用Selenium WebDriver驗證動態庫？

Question

問題：

畫廊中的圖像始終是動態的，但文章一直在變化。 當我單擊該文章時，圖像庫中會打開一個大圖像，而其他縮略圖會顯示一個輪播。

---

第一種情況：

我需要驗證圖像是否已加載並且圖庫是否正常 。 另外，其他縮略圖圖像也必須導航和驗證。

例：

• 1. 我在文章頁面上，並且打開了該文章，因此該文章頁面上有一個圖庫，其中包含> 5張縮略圖圖像。
• 2. 現在，我需要驗證圖像是否已打開，並且還要一個接一個地導航以驗證縮略圖。

---

第二種情況：

有時本文會加載圖像，有時會包含視頻或僅包含一個圖像。 所以這就是我要成為動態的意思。

所以每次圖像更改時，都需要知道如何處理這種情況，下面是html代碼：

<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>
    <div style="clear:both; float: none;"></div>
</div>

到目前為止，我所做的只是：

• 1. 打開URL。
• 2. 單擊文章頁面。
• 3. 現在打開該/任何文章。

我的第四步是在打開文章時驗證該圖像（帶有縮略圖）。 我無法執行第4步。 我現在沒有任何錯誤，直到第3步我都可以成功完成。

嗨，請像下面這樣

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 
        }
    }

}

}
