What's the relationship between Selenium RC and WebDriver?
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 ...
Read MoreBrowser Plugin Testing With Selenium.
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 MoreHow to maximize the browser window in Selenium WebDriver using C#?
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(); } ...
Read MoreCount of number of given string in 2D character array in C++
The following problem is an example of daily newspaper crossword, here we are given a 2-Dimensional character array and the problem statement is to find out the given word from the 2-Dimensional character array maze.The search algorithm includes finding the individual characters from Top-to-Bottom, Right-to-Left and vice-versa but not diagonally.Let us understand with examplesInput- String word-LAYS2D String[ ] - { "LOAPYS", "KAYSOT", "LAYSST", "MLVAYS", "LAYSAA", "LAOYLS" };Output- Count of number of given strings in 2D character array: 7Explanation - As we are given with the string array of words and from them, we have to find the word “LAYS” which can ...
Read MoreCount Occurrences of Anagrams in C++
We are given an input as a text stream and a word, and the task is to find out the count of occurrences of anagrams of the word in the given text stream. Anagrams are generated by rearranging letters from a word which ends up being a different word or phrase like anagrams of words in a statement "New York Times" can be formed as "Monkeys write".For ExampleInput: String string-: “workitwrokoffowkr” word = “work” Output: Count of occurrences of anagram in the string are: 3Explanation: The possible anagrams for the word “work” are work, wrok, rowk, owkr, etc. In the ...
Read MoreCount Strictly Increasing Subarrays in C++
We are given an array containing integer elements and the task is to firstly calculate the subarray out of the given array and then check whether the elements in a subarray are in increasing order or not. If yes, then we will consider the subarray else it will be discarded.The approach here is to stop further checking the subarray if the elements in 0th and 1th position are not in increasing order.For Example- in C++Input: int a[] = {1, 7, 5}Output: Count of strictly increasing subarrays is 1Explanation - The possible subarrays include {1, 7, 5}, {1, 7}, {7, 5} where ...
Read MoreCount numbers (smaller than or equal to N) with given digit sum in C++
Given a string str containing a number and a sum total as input. The goal is to find numbers upto str that have sum of digits equal to total.Let us understand with examples.For ExampleInput - N=”110” sum=5Output - Count of numbers smaller than or equal to N with given digit sum are: 7Explanation - The numbers upto 110 that have sum of digits equal to 5 are :-5, 14, 23, 32, 41, 50 and 104.Input - N=”1000” sum=3Output - Count of numbers smaller than or equal to N with given digit sum are: 10Explanation - The numbers upto 1000 that ...
Read MoreDivisibility by 64 with removal of bits allowed in C++ Program
In this tutorial, we are going to write a program that checks whether the given binary number is divisible by 64 or not.We have given a binary number and we can remove the bits to make it divisible by 64. After removing the bits, if the number is divisible by 64, then print Yes else No.The method that we are going to use is very simple. Let's see the steps to solve the problem.Initialize the binary number in string format.Iterate over the given binary number.Count the number of zeros.If the binary number contains more than or equal to 6 and ...
Read MoreDistributing all balls without repetition in C++ Program
In this tutorial, we are going to learn how to distribute n balls for k students without hurting anyone.The idea is simple, we have n balls in different colors that need to be distributed to the students. We don't have to give more than one ball of the same color to any student. If it is possible for a student to get more than one ball of the same color, then distribution should not happen.Let's see an example.Inputn = 10 k = 5 ballsColors = "rrrgbrbgbr"OutputYesNo color is more than the number of students (k). So, no student will get ...
Read MoreDensity of Binary Tree in One Traversal in C++ Program
In this tutorial, we are going to learn how to find the density of the binary tree in a single traversal.The density of the binary tree is obtained by dividing the size of the tree by the height of the tree.The size of the binary tree is the total number of nodes present in the given binary tree.The height of the binary tree is the max depth of the leaf node from the root node.Let's see the steps to solve the problem.Initialize the binary tree dummy data.Find the size and height of the tree.Recursively count the height of the tree.Return ...
