Sauce is thrilled to announce that we’ve integrated with Siesta by Bryntum!

Siesta is a JavaScript unit testing tool that can help you test any JavaScript code and also perform testing of the DOM and simulate user interactions. The tool can be used together with any type of JavaScript codebase – jQuery, Ext JS, NodeJS, Dojo, YUI etc. Using the API, you can choose from many types of assertions ranging from simple logical JS object comparisons to verifying that an HTML element is visible in the DOM. It comes in two versions: Lite and Standard. With Lite you can easily test your JavaScript in the browser, and with Standard you can also automate your tests (highly recommended).

Sauce is a cloud-based tool that enables you to securely test your web and mobile apps across 385+ browser/OS/platform/device combinations.

How does Siesta work with Sauce?

Siesta’s integration with Sauce is super easy since they’ve done most of the work under the hood. The main difference from the usual way you run WebDriver tests in Siesta is the addition of a --saucelabs argument, which will define the necessary credentials for connecting to Sauce and the --cap arguments which will specify the OS and browser combinations on which you want your tests to run. When you run Siesta tests using WebDriver, a standard command might look like this:

__SIESTA_DIR__/bin/webdriver http://localhost/myproject/tests/harness.html

For running the same test on Sauce’s hosted browsers, you’ll need to add your Sauce credentials and desired capabilities, like so:

__SIESTA_DIR__/bin/webdriver http://localhost/myproject/tests/harness.html --saucelabs SL_USERNAME,SL_KEY
--cap browserName=firefox --cap platform=windows

This command will then arrange a few things behind the scenes, like setting up the Sauce Connect tunnel so these tests can run locally and securely, and direct Sauce to execute the test specs on the latest version of Firefox on Windows. Of course, there are many desired capabilities and platforms you can choose to make sure you’re running tests according to the coverage that you need, and you can see all the different options on the Sauce Labs Platforms page.

What does the integration mean?

It’s become more than clear in the last few years that managing all the different browsers and operating systems out there, both desktop and mobile, is a whole lotta hassle and clearly better handled by a cloud-based service like Sauce Labs. But you need to ensure your JavaScript works from everywhere, and since you can now run your Siesta tests on any or all of Sauce’s 385 platform configurations, you can get that assurance with minimal effort and stay focused on the JavaScript code itself without having to invest your time and energy managing infrastructure.
