saucelabs

What is saucelabs?

The 'saucelabs' npm package provides a Node.js client for interacting with the Sauce Labs API. Sauce Labs is a cloud-based platform for automated testing of web and mobile applications. This package allows you to manage Sauce Labs resources, such as jobs, tunnels, and assets, programmatically.

What are saucelabs's main functionalities?

Managing Jobs

This feature allows you to manage and retrieve details about your Sauce Labs jobs. The code sample demonstrates how to get details of a specific job using its job ID.

const { SauceLabs } = require('saucelabs');
const saucelabs = new SauceLabs({ user: 'your-username', key: 'your-access-key' });

async function getJobDetails(jobId) {
  const job = await saucelabs.getJob(jobId);
  console.log(job);
}

getJobDetails('your-job-id');

Managing Tunnels

This feature allows you to manage Sauce Connect tunnels. The code sample demonstrates how to list all active tunnels.

const { SauceLabs } = require('saucelabs');
const saucelabs = new SauceLabs({ user: 'your-username', key: 'your-access-key' });

async function getTunnels() {
  const tunnels = await saucelabs.listTunnels();
  console.log(tunnels);
}

getTunnels();

Uploading Assets

This feature allows you to upload assets to a specific job. The code sample demonstrates how to upload a file to a job using its job ID.

const { SauceLabs } = require('saucelabs');
const saucelabs = new SauceLabs({ user: 'your-username', key: 'your-access-key' });

async function uploadAsset(jobId, filePath) {
  const response = await saucelabs.uploadJobAssets(jobId, { files: [filePath] });
  console.log(response);
}

uploadAsset('your-job-id', 'path/to/your/file');

Other packages similar to saucelabs

webdriverio

WebdriverIO is a popular testing utility for Node.js that provides a high-level API for browser automation. It supports multiple browser drivers and services, including Sauce Labs. Compared to the 'saucelabs' package, WebdriverIO offers a more comprehensive solution for writing and running tests, while 'saucelabs' focuses on managing Sauce Labs resources.

selenium-webdriver

Selenium WebDriver is a widely-used tool for browser automation. It provides bindings for multiple programming languages, including JavaScript. While Selenium WebDriver can be used with Sauce Labs for running tests on their cloud infrastructure, it does not provide the same level of resource management capabilities as the 'saucelabs' package.

cypress

Cypress is an end-to-end testing framework that aims to make testing fast, easy, and reliable. It provides a rich API for writing tests and a powerful test runner. While Cypress does not natively integrate with Sauce Labs, it can be configured to run tests on Sauce Labs infrastructure. Compared to 'saucelabs', Cypress focuses more on the testing experience and less on resource management.

As CLI Tool

This package if installed globally can be used as CLI tool to access the API from the command line:

$ npm install -g saucelabs
...
$ sl listJobs $SAUCE_USERNAME --limit 5 --region eu
{ jobs:
   [ { id: '19dab74f8fd848518f8d2c2cee3a6fbd' },
     { id: 'dc08ca0c7fa14eee909a093d11567328' },
     { id: '5bc6f70c777b4ae3bf7909a40f5ee41b' },
     { id: 'f40fe7b044754eaaa5f5a130406549b5' },
     { id: 'd1553f71f910402893f1e82a4dcb6ca6' } ] }

You can find all available commands and options with description by calling:

$ sl --help
# show description for specific command
$ sl listJobs --help

or update the job status by calling:

$ sl updateJob cb-onboarding 690c5877710c422d8be4c622b40c747f "{\"passed\":false}"

or download a job asset:

$ sl downloadJobAsset 690c5877710c422d8be4c622b40c747f video.mp4 --filepath ./video.mp4

or upload a job asset:

$ sl uploadJobAssets 690c5877710c422d8be4c622b40c747f --files ./video.mp4 --files ./log.json

or start Sauce Connect Proxy in EU datacenter:

# start Sauce Connect tunnel for eu-central-1 region
$ sl sc --region eu --tunnel-name "my-tunnel"
# run a specific Sauce Connect version
$ sl sc --scVersion 4.5.4
# see all available Sauce Connect parameters via:
$ sl sc --help

You can see all available Sauce Connect parameters on the Sauce Labs Docs.

As NPM Package

The following example shows how to access details of the last job you were running with your account that is being exposed as environment variables as SAUCE_USERNAME and SAUCE_ACCESS_KEY. Alternatively you can pass the credentials via options to the constructor:

import SauceLabs from 'saucelabs';
// if imports are not supported by your Node.js version, import the package as follows:
// const SauceLabs = require('saucelabs').default;

(async () => {
  const myAccount = new SauceLabs();
  // using constructor options
  // const myAccount = new SauceLabs({ user: "YOUR-USER", key: "YOUR-ACCESS-KEY"});

  // get full webdriver url from the client depending on region:
  console.log(myAccount.webdriverEndpoint); // outputs "https://ondemand.us-west-1.saucelabs.com/"

  // get job details of last run job
  const jobs = await myAccount.listJobs(process.env.SAUCE_USERNAME, {
    limit: 1,
    full: true,
  });

  console.log(jobs);
  /**
     * outputs:
     * { jobs:
        [ { browser_short_version: '72',
            video_url:

     */

  /**

   */
  const sc = await myAccount.startSauceConnect({
    /**

     */
    logger: (stdout) => console.log(stdout),
    /**

     * all parameters have to be applied camel cased instead of with hyphens, e.g.

     */
    tunnelName: 'my-tunnel',
  });

  // run a test
  // ...

  // close Sauce Connect
  await sc.close();

  // upload additional log files and attach it to your Sauce job
  await myAccount.uploadJobAssets('76e693dbe6ff4910abb0bc3d752a971e', [
    // either pass in file names
    './logs/video.mp4',
    './logs/log.json',
    // or file objects
    {
      filename: 'myCustomLogFile.json',
      data: {
        someLog: 'data',
      },
    },
  ]);
})();

You may wonder why listJobs requires a username as first parameter since you've already defined the process.env. The reason for this is that Sauce Labs supports a concept of Team Accounts, so-called sub-accounts, grouped together. As such functions like the mentioned could list jobs not only for the requesting account, but also for the individual team account. Learn more about it here

webdriverEndpoint property

You can use the webdriverEndpoint property of the client to get the full WebDriver endpoint to connect to Sauce Labs, e.g.:

const myAccount = new SauceLabs({
  user: 'YOUR-USER',
  key: 'YOUR-ACCESS-KEY',
  region: 'eu', // run in EU datacenter
});

// get full webdriver url from the client depending on `region` option:
console.log(myAccount.webdriverEndpoint);
// outputs: "https://ondemand.eu-central-1.saucelabs.com/"
