We can perform web scraping with Selenium webdriver and BeautifulSoup. Web Scraping is used to extract content from a page. In Python, it is achieved with the BeautifulSoup package.Let us scrap and get the below links on a page −Let us also see the html structure of the above links −Let us see how to do web scraping with BeautifulSoupTo install the required package for Beautifulsoup, we should run the below commands −pip install bs4 pip install requestsExamplefrom bs4 import BeautifulSoup import requests #get all response d=requests.get("https://www.tutorialspoint.com/about/about_careers.htm") #response content whole page in html format s = BeautifulSoup(d.content, 'html.parser') #access to ...

We can wait for an Ajax call to complete with Selenium webdriver. The determination of the load time of the page due to an Ajax response is a difficult task. This can be achieved with the help of synchronization concepts and wait methods in Selenium. Some of them are listed below −Implicit wait − It allows the web driver to wait for the time specified after which exception is thrown. This wait is applicable to all steps in the test.Syntaxdriver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);ExampleCode Implementation with implicit wait.import 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; public class AjaxImplWt{ public static ...

We can download a file at a specified location through Python and Selenium using the chromedriver. We shall use the ChromeOptions class for this purpose. First, we shall create an object of the ChromeOptions class.Then apply the add_experimental_option method on the object created. We shall pass browser preferences and download.default_directory: as parameters to that method. Finally, this information shall be passed to the driver object.Syntaxop = webdriver.ChromeOptions() p = {'download.default_directory':'C:\Users\ghs6kor\Downloads\Test'} op.add_experimental_option('prefs', p)Examplefrom selenium import webdriver from selenium.webdriver.chrome.options import Options #object of ChromeOptions class op = webdriver.ChromeOptions() #browser preferences p = {'download.default_directory':'C:\Users\ghs6kor\Downloads\Test'} #add options to browser op.add_experimental_option('prefs', p) #set chromedriver.exe path ...

We can start Safari with extension using SafariDriver in Selenium webdriver. Safari is a prominent browser and is provided by default by Apple devices. For Safari versions 10 and greater than 10, the safaridriver comes automatically and is not required to be installed separately.The location of the SafariDriver is: /usr/bin/safaridriver. Also, it must be remembered that to work with the Safari latest version, users should have the Apple machine. This is because the Apply no longer supports Safari on Windows (from 2012).If we are using an older version of Safari in the Apple machine, we have to turn on the ... Read More
There is a relationship between Selenium RC and Selenium webdriver. Prior to the introduction of Selenium webdriver, there was extensive usage of Selenium RC.Both the tools, supported automation tests to be executed in multiple browsers. Also, multiple programming languages can be used to implement the test cases. However, there are differences between them as listed below −FunctionalitiesSelenium RCSelenium WebdriverServerNeeds the server to trigger test execution.No need for the server to trigger test execution.Object OrientedNot much support from object oriented concepts.Majority of tests based on object oriented concepts.Dynamic LocatorsNo identification of elements with dynamic locators.Identification of elements with dynamic locators.AlertsNo support ...

We can perform browser plugin testing with Selenium webdriver. We can have single or multiple extensions of the Chrome browser while we manually open the browser and work on it.However, while the Chrome browser is opened through Selenium webdriver, those extensions which are available to the local browser will not be available. To configure an extension, we have to obtain the .crx extension file of the extension.Then we have to add the extension to the Chrome browser which is launched by Selenium. To get all the extensions available to the browser type chrome://extensions on the browser address bar.To get add ... Read More
We can maximize the browser window with Selenium webdriver in C#. This can be done with the help of the Maximize method. We shall launch the browser and then apply this method on the driver object.Syntaxdriver.Manage().Window.Maximize();For implementation we shall be using the NUnit framework.Exampleusing NUnit.Framework; using OpenQA.Selenium; using OpenQA.Selenium.Firefox; using System; namespace NUnitTestProject1{ public class Tests{ String u = "https://www.tutorialspoint.com/index.htm"; IWebDriver d; [SetUp] public void Setup(){ //creating object of FirefoxDriver d = new FirefoxDriver(); } ...

Given an array arr[] containing integer elements. The goal is to count the number of Arithmetic Progression subsequences inside arr[]. The range of elements inside arr[] are [1, 1000000].Empty sequence or single element will also be counted.Let us understand with examples.For ExampleInput - arr[] = {1, 2, 3}Output - Count of AP (Arithmetic Progression) Subsequences in an array are: 8Explanation - The following subsequences will form AP:-{}, {1}, {2}, {3}, {1, 2}, {2, 3}, {1, 3}, {1, 2, 3}Input - arr[] = {2, 4, 5, 8}Output - Count of AP (Arithmetic Progression) Subsequences in an array are: 12Explanation - The following subsequences ...

We are given a tree which can have endless levels, a variable child which will store the number of children a node can have, a variable weight which will store the weight associated with the path and a variable path that will store the path and task is to calculate the count of number of paths which has weights equals to the X and there must be an at least one edge with the given weight.For ExampleInput - int child = 4, weight = 4, path = 4; Output - Count of number of paths whose weight is exactly X and ...
