We can launch Edge browser with Selenium webdriver by using the Microsoft webdriver. We should also ensure that we are having the machine with the Windows 10 operating system.Navigate to the below link to download the Microsoft Edge driver executable file − https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/Once the page is launched, scroll down to the Downloads section, then choose and click the link which is compatible with our local Edge browser version.A zip file gets created, once the download is completed successfully. We have to then unzip the file and save it in a desired location. Then, set the path of the msedgedriver.exe file. ... Read More
We can handle multiple keyboard keys in Selenium webdriver by using the method Keys.chord. The multiple keyboard keys to be handled are passed as parameters to this method.The return type of the Keys.chord method is a string and can be applied to an element with the help of the sendKeys method. For example, in order to perform a select operation on text entered inside an edit box we require the keys ctrl+a to be pressed simultaneously.SyntaxString k = Keys.chord(Keys.CONTROL, "A"); driver.findElement(By.name("q")).sendKeys(k);Exampleimport org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import org.openqa.selenium.Keys; public class MultipleKeys{ public static void main(String[] ...

We can open new tabs in the same browser and switch between them using Selenium webdriver. Firstly, to open a new tab in the same browser we have to take the help of the methods – Keys.chord and sendKeys.The parameters Keys.CONTROL and Keys.ENTER are passed to the Keys.chord method. This method yields a string value and in turn passed as a parameter to the sendKeys method.SyntaxString n = Keys.chord(Keys.CONTROL, Keys.ENTER); driver.findElement(By.id("open-tab")).sendKeys(n);Once the second tab is opened, the getWindowHandles method is used to hold all the window handle ids in a Set. To shift the focus of the webdriver object to ... Read More
We can perform scroll up/down a page using Actions class in Selenium webdriver. First of all, we have to create an object of this Actions class and then apply the sendKeys method on it.Now, to scroll down a page, we have to pass the parameter Keys.PAGE_DOWN to this method. To again scroll up a page, we have to pass the parameter Keys.PAGE_UP to the sendKeys method. Finally, we have to use the build and perform methods to actually perform this action.SyntaxActions a = new Actions(driver); //scroll down a page a.sendKeys(Keys.PAGE_DOWN).build().perform(); //scroll up a page a.sendKeys(Keys.PAGE_UP).build().perform();Exampleimport org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; ...

We can open a browser window in full screen using Selenium webdriver in C# by using the method Maximize. This method has to be applied on the webdriver object.Syntaxdriver.Manage().Window.Maximize();Exampleusing NUnit.Framework; using OpenQA.Selenium; using OpenQA.Selenium.Firefox; using System; namespace NUnitTestProject1{ public class Tests{ String url = "https://www.google.com/"; IWebDriver driver; [SetUp] public void Setup(){ //object of FirefoxDriver driver = new FirefoxDriver(); } [Test] public void Test1(){ //URL launch driver.Navigate().GoToUrl(url); //browser maximize driver.Manage().Window.Maximize(); Console.WriteLine("Browser Maximized"); } [TearDown] public void closeBrowser(){ driver.Quit(); } } }Output
We can select an item from the sub-menu of a menu using mouse over action in Selenium webdriver with the help of the Actions class. We shall create an object of the Actions class and then apply moveToElement to it.This method shall move the mouse to the middle of the menu which displays submenu on mouse over. Then apply the perform method to actually perform this action. After hovering on the menu, we shall select a sub-menu with the help of the click method.SyntaxWebElement n=driver.findElement(By.id("nav-link-accountList")); Actions a = new Actions(driver); a.moveToElement(n).perform();Let us hover on the below highlighted menu on the ...

Word ChainLet's say word1 is a predecessor of word2 if and only if we can add exactly one letter anywhere in word1 to make it equal to word2. For example, "abc" is a predecessor of "abac".A word chain is a sequence of words [word_1, word_2, ..., word_k] with k >= 1, where word_1 is a predecessor of word_2, word_2 is a predecessor of word_3, and so on.ProblemWe are required to write a JavaScript function that takes in an array of strings, arr, as the first and the only argument.Each string in the array arr consists of English lowercase letters. Our ... Read More
ProblemJavaScript function that takes in an array of literals, arr, as the first and the only argument. This array contains some duplicates placed adjacently.Our function should rearrange the elements of the array such that no two elements in the array are equal. Our function should return the rearranged array, given that it's guaranteed that there exists at least one possible way of such arrangement.For example, if the input to the function is −const arr = [7, 7, 7, 8, 8, 8];Then the output should be −const output = [7, 8, 7, 8, 7, 8];Output Explanation:There may be other correct possible ...

Sequential Digits NumberA number has sequential digits if and only if each digit in the number is one more than the previous digit.ProblemWe are required to write a JavaScript function that takes in an array, arr, of exactly two elements specifying a range.Our function should return a sorted array of all the integers in the range arr (limits inclusive) that have sequential digits.For example, if the input to the function is −const arr = [1000, 13000];Then the output should be −const output = [1234, 2345, 3456, 4567, 5678, 6789, 12345];ExampleThe code for this will be − Live Democonst arr = [1000, ...

ProblemSuppose there are n people standing in a queue, we wish to distribute bananas to the people in the following way −We give 1 banana to the first person, 2 bananas to the second person, and so on until we give n bananas to the last person.Then, we go back to the start of the row, giving n + 1 bananas to the first person, n + 2 bananas to the second person, and so on until we give 2 * n bananas to the last person.This process repeats (with us giving one more banana each time, and moving to ...
