Browser Automation

This code sample demonstrates how to use the chromedriver package with Selenium WebDriver to automate a simple browser task. It opens Google, searches for 'webdriver', and waits for the search results page to load.

const { Builder, By, Key, until } = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');
const chromedriver = require('chromedriver');

chrome.setDefaultService(new chrome.ServiceBuilder(chromedriver.path).build());

(async function example() {
  let driver = await new Builder().forBrowser('chrome').build();
  try {
    await driver.get('http://www.google.com/ncr');
    await driver.findElement(By.name('q')).sendKeys('webdriver', Key.RETURN);
    await driver.wait(until.titleIs('webdriver - Google Search'), 1000);
  } finally {
    await driver.quit();
  }
})();

Headless Browser Testing

This code sample shows how to run Chrome in headless mode using the chromedriver package. Headless mode is useful for running tests in environments without a graphical user interface.

const { Builder, By, Key, until } = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');
const chromedriver = require('chromedriver');

chrome.setDefaultService(new chrome.ServiceBuilder(chromedriver.path).build());

(async function example() {
  let options = new chrome.Options();
  options.addArguments('headless');
  let driver = await new Builder().forBrowser('chrome').setChromeOptions(options).build();
  try {
    await driver.get('http://www.google.com/ncr');
    await driver.findElement(By.name('q')).sendKeys('webdriver', Key.RETURN);
    await driver.wait(until.titleIs('webdriver - Google Search'), 1000);
  } finally {
    await driver.quit();
  }
})();

Taking Screenshots

This code sample demonstrates how to take a screenshot of the current browser window using the chromedriver package. The screenshot is saved as a PNG file.

const { Builder, By, Key, until } = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');
const chromedriver = require('chromedriver');

chrome.setDefaultService(new chrome.ServiceBuilder(chromedriver.path).build());

(async function example() {
  let driver = await new Builder().forBrowser('chrome').build();
  try {
    await driver.get('http://www.google.com/ncr');
    await driver.findElement(By.name('q')).sendKeys('webdriver', Key.RETURN);
    await driver.wait(until.titleIs('webdriver - Google Search'), 1000);
    let screenshot = await driver.takeScreenshot();
    require('fs').writeFileSync('screenshot.png', screenshot, 'base64');
  } finally {
    await driver.quit();
  }
})();
