Explanation

Ensure you understand the command you just ran in the terminal:

curl -X POST https://saucelabs.com/rest/v1/USERNAME/js-tests
-u USERNAME:SAUCELABS-UNIQUE-KEY
-d platforms='[["Windows 8", "internet explorer", "10"], ["OS X 10.8", "safari", "6"]]'
-d url="https://saucelabs.com/test_helpers/front_tests/index.html"
-d framework=jasmine
-d name=sauce-sample-test

• curl -X POST https://saucelabs.com/rest/v1/USERNAME/js-tests - send a POST request to this REST endpoint specifying the JS Test we want to run.
• -u USERNAME:SAUCELABS-UNIQUE-KEY - authenticate with your Username and SauceLabs Key
• -d platforms='[["Windows 8", "internet explorer", "10"], ["OS X 10.8", "safari", "6"]]' - specify which Operating System and Browser Version you want to run your test in.
• -d url="https://saucelabs.com/test_helpers/front_tests/index.html" - url you want SauceLabs to test.
• -d framework=jasmine - the testing framework you want to run for this test
• -d name=sauce-sample-test - name of the test you are running (any string is valid)

Notes:

• While the JS tutorial on SauceLabs instructs you to setup Karma and use Mocha,
  these are by no means the only options for tools.
• Other (front-end) JavaScript testing frameworks are supported: including QUnit, Mocha, Jasmine and YUI.
• It is not immediately obvious in the docs, but in addition to these existing frameworks,
  you can also write custom tests: https://docs.saucelabs.com/reference/rest-api/#js-unit-testing

Conclusion

That's it! Now you know how to run a Cross-Browser Test on SauceLabs!

Performing SauceLab tests with a React app

• Install zuul by running npm i zuul --save-dev. Zuul allows you to host your tests on a port and communicate your test results with SauceLabs. It uses localtunnel.me to look after tunnels for you so you don't have to bother!
• After creating a SauceLabs account, create a file called .zuulrc in your HOME directory on your computer. Everyone running the tests from their local machine will need to do this individually. If you use atom, you can do this with the nifty shortcut: atom ~/.zuulrc. In the file, save the following details:

sauce_username: myusername
sauce_key: XXX

• Then create a .zuul.yml file in the ROOT directory of your project with the following format:

ui: tape
browsers:
  - name: chrome
    version: 27
  - name: ie
    version: 9..latest

• Note: You can add as many browsers as you want! If you want to see a list of all of the available browsers on zuul then type the follow into your terminal.

node_modules/.bin/zuul --list-available-browsers

• You're almost ready to run your SauceLabs tests! If you're using ES6 then you will need to bundle up your test files using webpack or browserify and babel.

• Run the following in your command line in the same directory as your two files:

node_modules/.bin/zuul --local 8080 --ui tape -- public/testBundle.js

(Change 'tape' to 'mocha-qunit' or whatever your testing framework is)

• Now logon to Saucelabs to watch your tests' progress on a whole range of browsers!
• More info on Saucelabs testing with Zuul can be found here
