My Testing Thoughts

At times, we need to visit a page in our application that automatically starts downloading the file which is as per the feature of that page. But we're navigating to this page (A) only to further navigate to the other page (B) by clicking on some link given on this page (A) which redirect us to the page (B) but at the same time, we don't want to download the file on visiting this page (A) as it's not required every time while running our Selenium automation script. Did you know there is a preference option "download_restrictions" that can help us achieve this? Let say A is this: http://selenium-release.storage.googleapis.com/2.41/selenium-java-2.41.0.zip HashMap<String, Object> prefs = new HashMap<String, Object>(); prefs.put("download_restrictions", 3); ChromeOptions opt = new ChromeOptions(); opt.setExperimentalOption("prefs", prefs); WebDriverManager.chromedriver().setup(); driver = new ChromeDriver(opt); ...

At times, we need to test many CSS values of an element on the page and look for a quick option to copy every attribute at once. Going to Styles tab in Dev Tools and copying 1 by 1 is a tedious thing. You can follow below-mentioned steps to extract all the CSS for any selected element using Chrome Dev Tool in one shot: 1. Right-click on a DOM node in the Elements Panel 2. Select Copy > Copy styles Sample for the image given below : font-style: inherit; font-family: "Open Sans",Helvetica,Arial,sans-serif; font-size: 18px; font-weight: 400; color: #333; display: inline-block; max-width: 170px; overflow: hidden; text-overflow: ellipsis; vertical-align: middle; white-space: nowrap; text-decoration: none; height: 24px; line-height: 24px;

1. Open a Chrome browser. 2. Open Dev Tools (Press F12). 3. Press CTRL+SHIFT+P (in windows) or cmd+SHIFT+P (in mac). 4. Type "screenshot" into the Command Menu and you will see options like "Capture area screenshot", "Capture full-size screenshot", Capture node screenshot" and "Capture screenshot". 5. Select your desired option and hit enter. Done... If you wish to, you can also emulate a device mode first and then take the screenshot- this way it will capture as per the device dimensions. Isn't it really handy when you want to take the screenshot of the entire page on any device like iPhone X?

In Selenium 4, there is an Interface for Chrome DevTools API that lets you play with DevTools. Here is a list of few things that we can achieve by using DevTools API with Selenium: 1. Use Console capabilities 2. Emulate network conditions 3. Perform security operations 4. Get performance and Metrics of our Browser/Network The complete API can be found here: https://lnkd.in/f7ffwZq Showing below how we can listen to Chrome Console logs and close the browser using the "Devtools" interface. public static void chromeDevTools() throws InterruptedException, IOException { try { chromeDevTools = driver.getDevTools(); chromeDevTools.createSession(); message = "Hi everyone, this is Dheeraj."; driver.get(" https://lnkd.in/fM5JmnZ "); // execute Script to write console message driver.executeScript("console.log('" + message + "');"); } catch (Exception e) { e.printStackTrace(); } finally { // C...

One of the ways to increase the speed and performance of your Selenium test is to execute in the headless mode. Also, as we know that disabling images helps to speed up the page load times which make execution faster- so sometimes during run (though NOT recommended for regular test run OR in the case where you flow requires interaction with images like clicking on the button which is an image), if we are not bothered too much whether images are loading on the page and want our execution to be faster- we can disable the images. public static void disableChromeImages(ChromeOptions options) { HashMap images = new HashMap(); images.put("images", 2); // 0-default, 1-Allow, 2-Block HashMap prefs = new HashMap(); prefs.put("profile.default_content_setting_values", images); options.setExperimentalOption("prefs", prefs); } public static void disableFireFoxImages(FirefoxOptions options) { FirefoxProfile profile = new FirefoxProfile(); profi...
