Read MoreHow to mute all sounds in chrome webdriver with selenium?
We can mute all sounds in Chrome with Selenium webdriver. To mute the audio we have to set parameters for the browser. For Chrome, we shall use the ChromeOptions class.We shall create an object of the ChromeOptions class. Then utilize that object to invoke the addArguments method. Then pass −mute−audio as a parameter to that method. Finally, send this information to the driver object.SyntaxChromeOptions op = new ChromeOptions(); op.addArguments("−−mute−audio"); WebDriver d = new ChromeDriver(op);For Firefox, we shall use the FirefoxOptions class and create an object for that class. Then utilize that object to invoke the addPreference method and pass media.volume_scale ...
Read MoreMake Selenium wait 10 seconds.
We can make Selenium wait for 10 seconds. This can be done by using the Thread.sleep method. Here, the wait time (10 seconds) is passed as a parameter to the method.We can also use the synchronization concept in Selenium for waiting. There are two kinds of wait − implicit and explicit. Both these are of dynamic nature, however the implicit wait is applied to every step of automation, the explicit wait is applicable only to a particular element.ExampleCode Implementation with sleep method.import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class WaitThrd{ public static void main(String[] args) throws ...
Read MoreMaximize WebDriver (Selenium 2) in Python.
We can maximize browser window with Selenium webdriver in Python. It is a good practise to maximize the browser while running the tests to reduce the chance of failure.Once a browser is maximized, the majority of elements become visible to the screen and the probability of interaction with the driver increases. Also, with a maximized browser, users have a better view of the elements on the page.Some of ways of maximizing browser −With the maximize_window methodSyntaxdriver.maximize_window()With the fullscreen_window methodSyntaxdriver.fullscreen_window()ExampleCode Implementation with maximize_window()from selenium import webdriver #set chromedriver.exe path driver = webdriver.Chrome (executable_path="C:\chromedriver.exe") # maximize browser driver.maximize_window() driver.get("https://www.tutorialspoint.com/index.htm") driver.close()ExampleCode Implementation with ...
Read MoreTake screenshot of full page with Selenium Python with chromedriver.
We can take a screenshot of a full page with Selenium webdriver in Python with chromedriver. First of all, we shall obtain the original window size with the get_window_size method.Then with the help of JavaScript Executor we shall fetch the complete height and width of the page which is opened on the browser. Then set the window size to that dimension with the set_window_size method.Next, capture the screenshot of the entire content within the body tag in the html with the screenshot method. This method accepts the path of the screenshot that will be captured as a parameter.Examplefrom selenium import ...
Read MoreHow could I start a Selenium browser(like Firefox) minimized?
We can start the Selenium browser(like Firefox) in minimized mode. This will be achieved by taking the help of the Dimension class. We shall create an object of this class.While creating the object , we shall pass the dimensions of the browser size as parameters to the Dimension class. Finally pass the object as parameter to the setSize method.SyntaxDimension s = new Dimension(100, 200); driver.manage().window().setSize(s);Exampleimport org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import java.util.concurrent.TimeUnit; import org.openqa.selenium.Dimension; public class FirefoxBrwSize{ public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "C:\Users\ghs6kor\Desktop\Java\geckodriver.exe"); WebDriver driver = new ...
Read MoreGet PID of Browser launched by Selenium.
We can PID of browsers launched by Selenium webdriver. First of all, we have to create an object of the webdriver.

Headless execution is getting popular now−a−days since the resource consumption is less and execution is done at a faster speed.Post version 59, Chrome supports headless execution. ChromeOptions class is utilized to modify the default characteristics of the browser. The addArguments method of the ChromeOptions class is used for headless execution and headless is passed as a parameter to that method.SyntaxChromeOptions opt = new ChromeOptions(); opt.addArguments("headless"); WebDriver drv = new ChromeDriver(opt);Exampleimport org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.chrome.ChromeOptions; import java.util.concurrent.TimeUnit; public class HeadlessChrome{ public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", ...
