Test Configuration

Before running a browser or device test with Sauce Labs, you need to write your test script to launch the platform/operating system/browser combination you want, and specify the location of the app for testing. You'll also want to configure other options, such as the path to your app.

Once your test is finished, you can annotate the job with a name, tags, and pass/fail status using the Sauce Labs REST API, or Selenium's JavaScript executor.

See Test Configuration Options for a list of valid test configuration options for tests run on Sauce Labs.

Getting Ready to Test#

Test configuration refers to setting the capabilities of your test within the test script itself. There are required capabilities for both Selenium and Appium tests, as well as an extensive set of optional capabilities (some of which are exclusive to Sauce Labs). You can use our Platform Configurator to create the required capabilities for your test scripts, or use one of our sample test frameworks to set up the capabilities for parallel testing across multiple platform/operating systems.

Capabilities for Selenium and Appium Tests#

You can configure the environment for your Appium and Selenium tests by specifying a set of capabilities. Our Platform Configurator can set test capabilities for testing in the scripting language of your choice. Test Configuration Options provides a complete list of all Selenium, Appium, and Sauce Labs testing capabilities.

Examples of Test Configuration Options for Website Tests#

You can test websites using either Selenium or Appium. Selenium has better support for desktop devices, while Appium has better support for testing websites on mobile devices with native browsers. However, website testing against Android devices with Appium is only supported for Android versions 4.4 and higher. All examples are for Java, but you can use our Platform Configurator to configure your tests in the language of your choice.

Default Selenium Version#

By default, Sauce Labs will use the following version of Selenium, depending on your selected combination of browser and operating system. While Selenium 3 is not yet fully implemented as a default version, it is supported for all Chrome and Firefox browsers on Mac and Windows platforms, for Safari 10+ on macOS 10.12 Sierra, and for Microsoft Edge and IE browsers version 10 and above. Currently Sauce Labs supports Selenium 3.4.0+ for Firefox and Safari and Selenium 3.5.0+ for Microsoft Edge and Chrome.

Browser NameDefault Selenium Version
Microsoft Edge2.52.0
ChromeLatest Chromedriver
FirefoxDev: 3.4.0
Beta: 3.4.0
53+: 3.4.0
39+: 2.53.1
Safari11.0: 3.4.0
< 11.0: 2.48.0
Internet Explorer2.53.1

You can set the Selenium version for your tests by using the seleniumVersion desired capability:

'seleniumVersion' = '3.8.1'

Examples for Selenium Mobile and Desktop Browsers#

With Selenium you can test against both desktop and mobile devices, though there are limitations with Android versions and devices.

Examples for Mobile Native Application Tests#

This following includes tips and examples of how to configure your mobile native application tests with Appium. For more detailed descriptions about the capabilities of Appium tests, check out the Server Capabilities section of the official Appium website. All examples are for Java, but you can use the Platform Configurator to set the capabilities in the language of your choice.

Mobile Native Application Test Configuration Tips#

Setting appiumVersion#

If you omit the appiumVersion in your test configuration, your test will be running with our default Appium version. Sauce recommends that you specify one of the newer Appium versions that provides a more extended API and fixes to known bugs.

Checking the Appium Version for Your Test#

  1. Log in to
  2. Find and select the test that you ran using Appium to view the Test Details page.
  3. Click the Metadata tab.
  4. Look for the Logs row and select Appium Log. The first line should indicate the Appium version. For example, 2014-05-05T17:45:07.541Z - info: Welcome to Appium v1.3.6.

Setting Browser Name#

When testing a native mobile application, the value for browserName is an empty string, as in caps.setCapability("browserName", "");

Setting the Location of the Mobile App#

If the application you want to test has been uploaded to a location other than our App Storage, you need to specify this location for app, and make sure that this location is accessible to Sauce Labs browsers. For example, caps.setCapability("app","");

Setting automationName for Android Apps#

If you're testing a native mobile app against Android versions 4.0 - 4.1, or a hybrid mobile against Android versions 4.0 - 4.2, you need to set the capability "automationName","selendroid". These Android versions are only supported via Appium’s bundled version of Selendroid, which utilizes Instrumentation. Later versions of Android are supported via Appium’s own UiAutomator library.

Enabling Location Services for iOS Devices#

If you want to enable location services in an iOS simulator, for example to test GPS-dependent applications, you should set these capabilities in your Appium test script:

  • locationServicesEnabled=true
  • locationServicesAuthorized=true
