You can configure the environment for your Appium and Selenium tests by specifying a set of desired capabilities. Our Platform Configurator can set desired 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.

See the following sections for more information.

Required Selenium Test Configuration Settings

SettingDescriptionKeyValue TypeExample

Browser Name

The name of the browser test against.

browserName string "browserName": "firefox"

Browser Version

The version of the browser you want to use in your test.browserVersion string 

"browserVersion": "latest"

Default to Latest Version of Chrome or Firefox

If you want to use the latest stable version of Google Chrome or Firefox that Sauce supports, you can use "browserVersion": "latest". You can also use "browserVersion": "latest-1" or "browserVersion": "latest-2", etc. to request the next most recent versions of a browser. For example, if the latest stable version of Chrome is 73, you can request "latest-2" to use Chrome 71. 

Microsoft Edge versions

Microsoft Edge has two version numbers, the browser application version and the EdgeHTML rendering engine version. For example, the current stable release of Edge as of November 2019 has the browser application version 44.17763 and the EdgeHTML version 18.17763. The Wikipedia page on Microsoft Edge covers this in more detail: https://en.wikipedia.org/wiki/Microsoft_Edge
It is the EdgeHTML version that should be specified here, such as "browserVersion": "18.17763".

Platform Name

Which operating system the browser should be running on.

platformNamestring "platformName": "macOS 10.13"

Required Appium Test Configuration Settings

SettingDescriptionKeyValue TypeExample
Appium VersionThe version of Appium that you want to run your tests with.appiumVersionstring

"appiumVersion": "1.5.3"

Default Appium Version

If you don’t select an Appium Version for your test in the Platform Configurator, this capability will automatically default to the latest version of Appium that is compatible with your selected OS. If you prefer to use a different version of Appium for your test, enter the version number you want as the value for the appiumVersion capability. You can find the release notes for each Appium version at the Appium GitHub repository. In order for you to have a window of time to check the compatibility of your test suites with the latest Appium version, it won't be set as the default version on Sauce until one week after the version release.  

Browser Name

The mobile web browser that will be automated in the simulator, emulator or device.browserNamestring

"browserName": "Safari"

Empty String for Mobile Native and Hybrid Apps

If you're testing a mobile native or web application, the value for this capability should be an empty string.

Device Name

The name of the simulator, emulator, or device you want to use in the test.deviceNamestring

"deviceName": "Google Nexus 7 HD Emulator"

Generic Android Emulator

For an Android emulator test you can request a generic Android emulator by using the option "deviceName":"Android Emulator". If you want to use an Android emulator that looks and feels like a specific Android phone or tablet, for example a Google Nexus 7 HD Emulator or a Samsung Galaxy S4, then instead of "deviceName":"Android Emulator", you need to specify the exact Android emulator skin to use, for example "deviceName":"Samsung Galaxy S4 Emulator".

Emulator Skins and Configurations

Each Android emulator skin will have a different configuration depending on the phone or tablet that it emulates. For example, all the skins have different resolutions, screen dimensions, pixel densities, memory, etc. You can use the Platform Configurator to get a list of the available Android emulator skins for the various Android emulator versions.

Platform Version

The mobile operating system version that you want to use in your test. platformVersionstring"platformVersion": "9.1"

Platform Name

The mobile operating system platform you want to use in your test.platformNamestring"platformName": "iOS"

Application Path

The path to a .ipa, .apk or .zip file containing the app to test. This could be the location of your app in the Temporary Sauce Storage, for example, sauce-storage:myapp.zip, or the URL to a remote location where your app is located, for example http://myappurl.zip/.appstring

"app": "sauce-storage:my_app.zip"

Required for Mobile Native and Hybrid Apps Only

This capability is required only for testing mobile native or web applications.

    How do I simulate clicking on a link opens in a new tab?? How to I set the desired capabilities to open a link in new tab? I tried to set safariOpenLinksInBackground to true and to false. But it just opens the link in the same page.

    I am getting the error The Sauce VMs failed to start the browser or device.

    I am using the following desired capabilities  generated by the Platform configurator

    DesiredCapabilities caps = DesiredCapabilities.android();
    caps.setCapability("appiumVersion", "1.5.3");
    caps.setCapability("deviceName","Samsung Galaxy S4 Emulator");
    caps.setCapability("deviceOrientation", "portrait");
    caps.setCapability("browserName", "");
    caps.setCapability("platformVersion","4.4");
    caps.setCapability("platformName","Android");
    caps.setCapability("app","sauce-storage:com.google.android.youtube_11.35.60-113560130.apk");
