I need to test images on a webpage. How should I deal with the following situation:

  1. To check whether all images are loaded.
  2. To check if broken images are loaded.
  3. To that the description in Alt="" if the image is not loaded.

Kindly suggest how should I do this. I need a code in Java which works like the like given: http://tools.seochat.com/tools/broken-links-images-tool

    Did you try any code? no one will give you ready made full code. You should try and share your code when you get problem. – Helping Hands Jan 21 '15 at 12:30
  • Hi kate, I tried using following code which i took from web, i tried manipulating code but it was not successful. – Rajesh Rathod Jan 22 '15 at 12:34
  • Hello John, could you provide your code in the question? – amazpyel Jan 22 '15 at 22:00

With Selenium

I am not sure Selenium should be used as a link/image checker. In an ideal world you would define which images are on a page, if the images exist you could check their ALT tag. Then your tests verifies those predefined situations are still there.

This blog post shows how you can find images based on their ALT content:

driver.findElement(By.cssSelector("img[alt='Previous']"));

I get the feel you looking for some code that magically detects what images exist on a page and if they are correct. This is what some link checkers do, they check the source of an image or link exists. Then check if they have a ALT text, but do not check the correct value. The tool you linked to is a web-based tool and the magic happens on their back-end. You cannot re-use their work without the back-end code.

This blog post shows how you can loop tru all images on a page with Selenium in Java. If you combine that with the first blog post you can then check the ALT text:

public class findbrokenimages {
  static int invalidimg;
  static WebDriver driver ;
  public static void main(String[] args) {
    try {
      driver = new FirefoxDriver();
      driver.get("http://ruchi-myseleniumblog.blogspot.in");
      invalidimg = 0;
      List allImages  = driver.findElements(By.tagName("img"));
      System.out.println("Total  images are " + allImages.size());
      for (int i = 0; i < allImages.size(); i++) {
        WebElement img = (WebElement) allImages.get(i);
        if (img != null) {
          verifyimgActive(img);
        }
      }
      System.out.println("Total invalid images are " + invalidimg);
      driver.quit();
    } catch (Exception e) {
      e.printStackTrace();
      System.out.println(e.getMessage());
    }
  }

  public static void verifyimgActive(WebElement img) {
    try {
      HttpResponse response = new DefaultHttpClient().execute(new HttpGet(img.getAttribute("src")));
      if (response.getStatusLine().getStatusCode() != 200)
      invalidimg++;
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

Also look into the .getAttribute() function of a WebElement: https://stackoverflow.com/questions/23394828/how-to-get-the-value-of-an-attribute-using-xpath
