What is selenium-webdriver?
The selenium-webdriver npm package is a browser automation library that provides an API for interacting with web browsers. It allows for the automation of web applications for testing purposes, but it's also used for automating web-based administration tasks. It supports multiple browsers including Chrome, Firefox, Internet Explorer, and Safari.
What are selenium-webdriver's main functionalities?
Browser Navigation
This feature allows for navigating to a web page. The code sample demonstrates how to open Firefox and navigate to Google's homepage.
const {Builder} = require('selenium-webdriver');
let driver = new Builder().forBrowser('firefox').build();
driver.get('http://www.google.com');
Element Interaction
This feature enables interaction with elements on a web page, such as input fields and buttons. The code sample shows how to find a search input by its name attribute and type 'selenium' into it.
const {Builder, By} = require('selenium-webdriver');
let driver = new Builder().forBrowser('firefox').build();
driver.findElement(By.name('q')).sendKeys('selenium');
Wait for Elements
This feature allows scripts to wait for elements to become available or visible on the page before interacting with them. The code sample demonstrates waiting up to 10 seconds for a search input to be located.
const {Builder, By, until} = require('selenium-webdriver');
let driver = new Builder().forBrowser('firefox').build();
driver.wait(until.elementLocated(By.name('q')), 10000);
Other packages similar to selenium-webdriver
puppeteer
Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol. It is similar to selenium-webdriver but is specifically designed for Chrome and Chromium browsers. Puppeteer is often considered faster for browser automation tasks, especially with headless Chrome.
webdriverio
WebdriverIO is an automation library that wraps around the W3C WebDriver API. It provides a simpler API compared to selenium-webdriver and integrates well with modern testing frameworks. WebdriverIO supports both web and mobile browsers, making it a versatile choice for cross-platform testing.
nightwatch
Nightwatch.js is an automated testing framework for web applications and websites, written in Node.js. It uses the W3C WebDriver API for browser automation. It is designed to simplify the process of setting up continuous integration and writing automated tests. Nightwatch has a cleaner syntax compared to selenium-webdriver, which might be easier for beginners.
