Get rid of "Timed out receiving message from renderer"

Get rid of "Timed out receiving message from renderer" Message Well, if you using selenium web driver to automate your web flows you must be really annoyed by now with the console log [SEVERE]: Timed out receiving message from renderer: 0.100 This not only gives us a false impression of some error happening during the run but also makes it difficult to go over the console logs. Luckily, we can make use of the silent output mode in chrome to get rid of these messages. To do so we need to set the silentOutput parameter to true in System property as follows. System.setProperty("webdriver.chrome.silentOutput", "true"); and voila...no more annoying timeout message.   If you don't want to use setting the system property way for any reason, there is another way for you to achieve this. You can make use of ChromeDriverService builder to build it with " withSilent " set to true in the code as below.   ChromeDriverService.Builder bu...

Selenium - How to initialize Chrome and Firefox WebDriver

-
Selenium - How to initialize Chrome and Firefox WebDriver: What is WebDriver: Its important we understand what is WebDriver, before jumping to use it to initialize the browsers. WebDriver API was introduced with Selenium 2.0 and was the primary feature of it. WebDriver is designed to provide a simpler, more concise programming interface, overcome the limitations of Selenium RC (such as Single Host origin policy) and provide better support for modern advanced web applications. It was developed to better support dynamic web pages where elements of a page may change without the page itself being reloaded.  The way Selenium RC worked was injecting javascript functions into the browser when the browser was loaded and then used its javascript to execute the commands in the browser. WebDriver makes direct calls to the browser and drives the browser directly using the browser’s built in support for automation One of the most common interview question is whethe...
