browserstack

What is browserstack?

The browserstack npm package allows developers to interact with the BrowserStack API, enabling automated testing of web applications across various browsers and devices. It provides functionalities for managing browser sessions, running tests, and retrieving test results.

What are browserstack's main functionalities?

Start a Browser Session

This feature allows you to start a new browser session on BrowserStack. You can specify the operating system, browser, and URL to be tested. The code sample demonstrates how to create a new worker (browser session) using the BrowserStack API.

const browserstack = require('browserstack');
const client = browserstack.createClient({
  username: 'your-username',
  password: 'your-access-key'
});

client.createWorker({
  os: 'Windows',
  os_version: '10',
  browser: 'chrome',
  browser_version: 'latest',
  url: 'http://www.example.com',
  timeout: 300
}, function(error, worker) {
  console.log(worker);
});

Stop a Browser Session

This feature allows you to stop an existing browser session. The code sample shows how to terminate a worker (browser session) using its ID.

client.terminateWorker(worker.id, function(error, data) {
  console.log(data);
});

Retrieve Test Results

This feature allows you to retrieve the details and results of a specific browser session. The code sample demonstrates how to get the status and details of a worker using its ID.

client.getWorker(worker.id, function(error, worker) {
  console.log(worker);
});

Other packages similar to browserstack

selenium-webdriver

Selenium WebDriver is a popular tool for automating web application testing. It provides a more extensive set of functionalities for browser automation compared to BrowserStack, but it requires setting up and managing your own browser infrastructure.

cypress

Cypress is a modern end-to-end testing framework that provides a rich set of features for testing web applications. Unlike BrowserStack, Cypress runs tests directly in the browser and provides a more developer-friendly experience with real-time reloading and debugging.

testcafe

TestCafe is an end-to-end testing framework that allows you to write tests in JavaScript or TypeScript. It provides a simple API and does not require browser plugins. TestCafe can run tests on multiple browsers and devices, similar to BrowserStack, but it does not offer the same level of cross-browser testing infrastructure.

node-browserstack

A node.js JavaScript client for working with BrowserStack through its REST API (aka Javascript Testing API), Automate API, App Automate API, and Screenshots API.

Installation

npm install browserstack

Usage

var BrowserStack = require("browserstack");
var browserStackCredentials = {
	username: "foo",
	password: "p455w0rd!!1"
};

// REST API
var client = BrowserStack.createClient(browserStackCredentials);

client.getBrowsers(function(error, browsers) {
	console.log("The following browsers are available for testing");
	console.log(browsers);
});

var automateClient = BrowserStack.createAutomateClient(browserStackCredentials);

automateClient.getBrowsers(function(error, browsers) {
	console.log("The following browsers are available for automated testing");
	console.log(browsers);
});

// App Automate API
// Show the upload builds for mobile app automation
var appAutomateClient = BrowserStack.createAppAutomateClient(browserStackCredentials);

appAutomateClient.getBuilds(function(error, builds) {
	console.log("The following builds are available for app automated testing");
	console.log(builds);
});
