WebDriver

A lightweight, non-opinionated implementation of the WebDriver specification including mobile commands supported by Appium

There are tons of Selenium and WebDriver binding implementations in the Node.js world. Every one of them have an opinionated API and recommended way to use. This binding is the most non-opinionated you will find as it just represents the WebDriver specification and doesn't come with any extra or higher level abstraction. It is lightweight and comes with support for the WebDriver specification and Appium's Mobile JSONWire Protocol.

The package supports the following protocols:

• WebDriver
• Appium
• Chromium (additional Chromedriver specific commands)
• Selenium (additional Selenium WebDriver specific commands)
• Sauce Labs (Sauce Labs specific WebDriver extensions)
• JSONWireProtocol (depcrecated)
• Mobile JSONWireProtocol (depcrecated)

Commands are added to the clients protocol based on assumptions of provided capabilities. You can find more details about the commands by checking out the @wdio/protocols package. All commands come with TypeScript support.

Install

To install this package from NPM run:

npm i webdriver

Example

The following example demonstrates a simple Google Search scenario:

import WebDriver from 'webdriver';

(async () => {
    const client = await WebDriver.newSession({
        path: '/',
        capabilities: { browserName: 'firefox' }
    })

    await client.navigateTo('https://www.google.com/ncr')

    const searchInput = await client.findElement('css selector', '#lst-ib')
    await client.elementSendKeys(searchInput['element-6066-11e4-a52e-4f735466cecf'], 'WebDriver')

    const searchBtn = await client.findElement('css selector', 'input[value="Google Search"]')
    await client.elementClick(searchBtn['element-6066-11e4-a52e-4f735466cecf'])

    console.log(await client.getTitle()) // outputs "WebDriver - Google Search"

    await client.deleteSession()
})()
