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.

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()
})()
