海外TECH	DEV Community	How To Find Broken Images Using Selenium WebDriver?	https://dev.to/himanshusheth004/how-to-find-broken-images-using-selenium-webdriver-i9b	How To Find Broken Images Using Selenium WebDriver A web product s user experience is one of the key elements that help in user acquisition and user retention Though immense focus should be given to the design amp development of new product features a continuous watch should be kept on the overall user experience Like pages or dead links broken images on a website or web app could also irk the end users Manual inspection and removal of broken images is not a feasible and scalable approach Instead of using third party tools to inspect broken images you should leverage Selenium automation testing and see how to find broken images using Selenium WebDriver on your website In this part of the Selenium Tutorial we look at how to find broken images on websites using Selenium WebDriver From an end user s perspective even a single broken image on a page could be an experience dampener a prime reason to find broken images on websites By the end of this blog you would be able to find broken images using Selenium WebDriver with Python Java C and PHP What are Broken Images in Web Testing Broken image is a link image that does not show up as a picture clicking upon which takes the end user to a defunct picture The user encounters a Error when clicked on the broken image This error means that there is an issue with the image URL and the image is not loaded properly due to various reasons Shown below is an example of broken images on a website From an end user experience and retention point of view fixing broken images should be considered equally important as fixing broken links on websites Selenium WebDriver can be used to find broken images on websites The internal logic for locating broken images might vary based on how the images are fetched from the server Here are two ways in which images are read from the server Absolute Path As the name indicates the website uses the absolute path or complete path in the src attribute that specifies the path to the intended image The lt img gt tag in HTML creates a holding space for the referenced image Shown below is an example of usage of an absolute path in the src attribute of the lt img gt tag The image shown above is fetched from an absolute location i e the HostName is used in the lt src gt attribute Relative Path On many websites a relative image on a path is placed in the attribute The relative path is always relative to the root of the document i e website web app For example in lt img src assets img image jpg alt some text gt the path of image jpg is relative to the root If the website URL is the relative path of the image image jpg will equate to Here is a sample usage of relative path in the lt src gt attribute of the lt img gt tag You would be curious to know what leads to broken images on a website Let s look at the why part of broken images Major reasons for Broken images on a webpageHere are some of the prominent reasons that lead to broken images i e file not found or error for images on a website or web apps Incorrect Image Format In case you have uploaded the image in a jpg format but the image is identified as a png format in the code it leads to an error when the image is getting displayed It is necessary to ensure that the image formats coincide when uploading to the server and referring to the same in the code Incorrect Image URL When rendering the specified image the browser reads the image location from the lt src gt attribute in the lt img gt tag If a wrong image path or incorrect filename is mentioned in the lt src gt attribute it leads to issues in displaying the image and errors Deleted Image file The HTML code link could be referring to a file that is either wrongly spelled in the code or no longer exist on the server Site relocation After relocating the site from one provider to another a thorough check should be conducted to verify whether all the site assets are available and accessible on the new server redirection During a website redesign activity redirects should be done for the site content and the images used on the site Along with the redirection of URLs utmost attention should be given to the redirection of the images that reside in those URLs Unavailability of the server In scenarios where the server does not give a response within a certain time frame images would fail to appear on the site Like broken links attention should be given to ensure that your web product is free from broken images Why should you check for broken images Here are the two major reasons for checking for broken images on websites Broken images on a website hamper the end user experience which could negatively impact the growth of the product Images are an essential part of the content marketing strategy However broken images could create SEO issues Images with missing ALT tags and broken internal images are problematic from an SEO point of view and should be looked into on a high priority How to Find Broken Images Using Selenium WebDriver When a user visits a website the user request is sent to the website s server which processes the request In response to the browser s request the server sends a three digit code referred to as the HTTP Status Code to the browser Some of the commonly used classes of HTTP Status Codes are xx xx xx xx and xx To find broken images using the Selenium WebDriver we would be using the xx class of status code indicating that the particular page or the complete website is not reachable The status code of class xx particularly suggests that the request sent by the web browser was successful and the appropriate response was sent to the browser When an image is not available on the server a response code Page Not Found is sent to the web browser You can refer to our earlier blog for detailed information on HTTP Status Codes and Status Codes presented on the detection of broken links images Irrespective of the programming language being used to detect broken images the basic principles remain the same Here are some of the steps that can be followed to find broken images on websites Use the lt img gt tag to collect details of the images present on the page For each lt img gt tag get the attribute lt src gt from the tag Convert the path obtained from the lt src gt attribute to an Absolute Path Conversion to absolute path might not be required for Selenium Java Selenium C and Selenium Python Converting the relative path of the image s to absolute path is a must when Selenium PHP is used Send an HTTP request to the image link obtained from step and capture the response code received in response to the request Based on the response code sent by the server you should validate whether the image is broken Response code i e HttpStatusCode OK means that the image is available on the server Validate whether the link is broken or not based on the response code sent by the server Repeat steps for every image present on the page The naturalWidth attribute returns the original width of the image and it is zero for a broken image For Selenium with Java you could also check if the naturalWidth attribute of the image is zero or not In this Selenium Tutorial we demonstrate how to find broken images using Selenium WebDriver in Java Python C and PHP The tests are run on the latest version of the Chrome Browser on the Windows platform The execution is carried out on the cloud based Selenium Grid provided by LambdaTest To get started with LambdaTest you should create an account on the website and note the user name amp access key from the profile section on LambdaTest The browser capabilities are generated using LambdaTest Capabilities Generator Here is the test scenario to find broken images on the website Test ScenarioGo to on Chrome latest Read the details about the images present on the pageSend HTTP request for each imageCheck the response code of the HTTP request If the response code is the image is not broken else the image is broken Print whether the image is broken or not on the terminalThe URL under test has two broken images and two proper images Shown below are the two broken images on the website Here are the two proper or not broken images on the website How to find

HttpResponse import org apache http client HttpClient import org apache http client methods HttpGet import org apache http impl client HttpClientBuilder Find all the images on the pageThe findElements method in Selenium is used for fetching the details of all the images present on the page The images are located using the tagName img The images are placed in a list which will be further iterated to find broken images on the page List lt WebElement gt image list driver findElements By tagName img System out println The page under test has image list size images Create a new instance of HttpClientThe HttpClient class offers an API that primarily consists of three core classes HttpClient HttpRequest and HttpResponse HttpResponse describes the result of an HttpRequest call For reading the response body we create a new instance of HttpClient and request the objects The new instance of the class is created with the build method of HttpClientBuilder class HttpClient client HttpClientBuilder create build Create a new instance of HttpGetCloseableHttpClient provides the execute method for sending and receiving the data The execute method uses the parameter of type HttpUriRequest which has many sub classes including HttpGet and HttpPost We first create a new HttpGet object with the HttpUriRequest set to path retrieved by reading the src attribute in the WebElement img HttpGet request new HttpGet img getAttribute src For example getAttribute “src for the image “Fork me on GitHub will return img forkme right green png Retrieve the response objectThe execute method executes the HTTP request using the default context It returns the response body i e HttpResponse HttpResponse response client execute request Read the Status CodeThe getStatusLine method of the HttpResponse class obtains the status line of the response obtained from step The getStatusCode method returns the HttpStatus in an integer format Response Code SC OK means that the HTTP request was executed successfully if response getStatusLine getStatusCode System out println img getAttribute outerHTML is broken iBrokenImageCount If HttpStatus is the concerned image is not broken whereas HttpStatus for a broken image is Steps thru are repeated for all the WebElement entries in the image list The outerHTML attribute for the broken images is printed for reference on the terminal Code Walkthrough Approach Find all the images on the pageSimilar to Step in Approach the findElements method in Selenium is used to fetch the details of images present on the image The tagName img is used with the findElements method to achieve the same List lt WebElement gt image list driver findElements By tagName img Read the naturalWidth attributeThe naturalWidth attribute of the WebElements identified in Step is read For broken images naturalWidth will be zero whereas it is non zero for normal images if img getAttribute naturalWidth equals System out println img getAttribute outerHTML is

return scheme abs path gt Code WalkthroughTo find broken images with Selenium PHP we would be using the PHPUnit framework with Selenium Refer to our detailed Selenium PHP tutorial for a quick recap on Selenium with PHPUnit Run the command composer require on the terminal for installing the packages mentioned in composer json Here is the overall walkthrough of the source code Read the page sourceHTML source of the page under test i e is read using the file get contents function in PHP HTML source is read in a local String variable html html file get contents test url Instantiate the DOMDocument classThe entire HTML document is represented in the DOMDocument class It also serves as the root of the source tree htmlDom new DOMDocument Parse HTML source of the pageDOMDocument loadHTML function in PHP parses the HTML source available in the String variable html The function returns a DOMDocument object when executed successfully htmlDom gt loadHTML html Extract the Images using img tagEntries in the lt img gt HTML tag are read using the getElementsByTagName method of the DOMDocument class As we are looking for broken images search is based on the lt img gt tag from the parsed HTML source image list htmlDom gt getElementsByTagName img Read the entries enclosed in src attributeThe values of the src attribute are read from the lt img gt entries extracted in Step img path img gt getAttribute src For example The src attribute in lt img src img avatar blank jpg gt is “img avatar blank jpg Convert the relative path to absolute pathThis step is only applicable if the src attribute in the lt img gt tag returns a relative path from the root of the document In the case of the images are read using the relative path Take the LambdaTest blog case the images in the blogs are read using the absolute path of the images on the server Shown below is an example of how the absolute path of the image is used in the src attribute of the lt img gt tag We created a new function relativeabsolute that takes the following arguments relative path obtained from the lt src gt attribute and root document of the URL under test lt phpfunction relativeabsolute rel path base path return if already absolute URL if parse url rel path PHP URL SCHEME return rel path queries and anchors if rel path rel path return base path rel path parse base URL and convert to local variables scheme host path extract parse url base path Relative Path Sample For the relative path would equate to img path If the img path is img avatar blank jpg the final relative path used by the relativeabsolute function would be img avatar blank jpg The base URL is set to test url Convert relative path to absolute path search path img path abs path relativeabsolute search path base url Absolute path Sample If an absolute path is used in the lt src gt attribute the absolute path and the relative path would be the same In such a scenario Step becomes optional test url img path img gt getAttribute src abs path img path We came up with the relativeabsolute function with support from the StackOverflow Community Convert the relative path to absolute pathThe get headers function is used to fetch all the headers sent by the server in response to the HTTP request For a broken image the HTTP status code is whereas the status code is if the image is present on the server The preg match function in PHP does a case insensitive search for “ HTTP Status Code if the request is completed successfully in the response code The local variable iBrokenImageCount is incremented when a broken image is present on the page response get headers abs path if preg match response print abs path is not broken n else print abs path is broken n iBrokenImageCount iBrokenImageCount ExecutionTo run the test that is using the PHPUnit framework run the following command from the root folder vendor bin phpunit debug testWhen the test is run against it shows that the page has two broken images We executed the same test against the LambdaTest blog after doing the minimal changes in the code under the For a site with absolute path comment The site uses the absolute path in lt src gt attribute of img tag As seen below there are zero broken images on the LambdaTest blog That s all folksLike broken links on web pages broken images could also hinder the overall user experience It also creates a negative impact on the search rankings thereby hampering your SEO efforts Instead of relying on third party tools where you are putting the privacy amp data at stake you should find broken images using Selenium WebDriver In this Selenium tutorial we had a look at how to find broken images using Selenium WebDriver with Java Python C and PHP languages What strategy do you follow for finding broken images on webpage s Do leave your thoughts in the comments section…Happy Testing	2021-04-13 10:01:11
