java - 如何在selenium webdriver中定位动态变化的图像？

Question

有人要求我自动化在线购物网站的代码，将商品添加到购物车并结账，但我陷入了困境。

该项目的图像不断变化，因此它的 xpath 也不断变化。我正在使用操作来执行鼠标悬停功能，但它不起作用并且出现错误

Exception in thread "main" org.openqa.selenium.TimeoutException: Timed out after 50 seconds waiting for visibility of element located by By.xpath: html/body/

请找到下面的代码:

w.get("http://www.provogue.com/new-arrivals");
WebDriverWait wait= new WebDriverWait(w,30);
Actions action = new Actions(w);
WebElement elem = w.findElement(By.xpath("html/body/div[2]/div/div/div[2]/div/div[2]/div[2]/ul[1]/li[2]/div[2]/a[1]/div/img[1]"));
wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("html/body/div[2]/div/div/div[2]/div/div[2]/div[2]/ul[1]/li[2]/div[2]/a[1]/div/img[1]")));
action.moveToElement(elem).click();
action.build().perform();

上述代码中使用的定位器不正确。要单击第一行中的第二个商品并将其添加到购物车，请使用以下代码

         driver.get("http://www.provogue.com/new-arrivals");

         driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);

         //click on the first row ul[1] second item li[2] 

         driver.findElement(By.xpath("//div[@class='category-products']/ul[1]/li[2]/div[2]/a/img")).click();

         //wait for the iframe to load and then switch to it

         WebDriverWait wait = new WebDriverWait(driver, 30000);
         wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt((By
                         .className("fancybox-iframe"))));

         //select size and then

         //click on Add to cart button

         driver.findElement(By.xpath("//button[@title='Add to Cart']")).click();

         //switch back to default content

         driver.switchTo().defaultContent();

编辑

   driver.get("http://www.provogue.com/new-arrivals");

     driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);

     //click on the first row ul[1] second item li[2] 

     Actions actions = new Actions(driver);
     WebElement productImage = driver.findElement(By.xpath("//div[@class='category-products']/ul[1]/li[2]/div[2]/a[@class='product-image']"));
     actions.moveToElement(productImage).perform();
     WebElement ViewLink = driver.findElement(By.xpath("//div[@class='category-products']/ul[1]/li[2]/div[2]/a[@class='fancybox']"));
     actions.moveToElement(ViewLink);
     actions.click();
     actions.perform();
     //wait for the iframe to load and then switch to it

     WebDriverWait wait = new WebDriverWait(driver, 30000);
     wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt((By
                     .className("fancybox-iframe"))));

     //select size and then

     //click on Add to cart button

     driver.findElement(By.xpath("//button[@title='Add to Cart']")).click();

     //switch back to default content

         driver.switchTo().defaultContent();
}

我已经测试了上面的代码，它工作正常
