WebdriverIO Sauce Service

WebdriverIO service that provides a better integration into Sauce Labs. This service can be used for:

the Sauce Labs Virtual Machine Cloud (Desktop Web/Emulator/Simulator)
the Sauce Labs Real Device cloud (iOS and Android)

It can update the job metadata ('name'*, 'passed', 'tags', 'public', 'build', 'custom-data') and runs Sauce Connect if desired.

What else will this service do for you:

By default the Sauce Service will update the 'name' of the job when the job starts. This will give you the option to update the name at any given point in time.
You can define a setJobName parameter and customise the job name according to your capabilities, options and suite title
The Sauce Service will also push the error stack of a failed test to the Sauce Labs commands tab
It will allow you to automatically configure and spin up Sauce Connect
And it will set context points in your command list to identify which commands were executed in what test

Installation

The easiest way is to keep @wdio/sauce-service as a devDependency in your package.json, via:

npm install @wdio/sauce-service --save-dev

Instructions on how to install WebdriverIO can be found here.

Configuration

To use the service for the Virtual Desktop/Emulator/Simulator Machine and Real Device cloud you need to set user and key in your wdio.conf.js file. It will automatically use Sauce Labs to run your integration tests. If you run your tests on Sauce Labs you can specify the region you want to run your tests in via the region property. Available short handles for regions are us (default) and eu. These regions are used for the Sauce Labs VM cloud and the Sauce Labs Real Device Cloud. If you don't provide the region, it defaults to us.

If you want WebdriverIO to automatically spin up a Sauce Connect tunnel, you need to set sauceConnect: true. If you would like to change the data center to EU add region:'eu' as US data center is set as default.

// wdio.conf.js
export const config = {
    // ...
    user: process.env.SAUCE_USERNAME,
    key: process.env.SAUCE_ACCESS_KEY,
    region: 'us', // or 'eu'
    services: [
        ['sauce', {
            sauceConnect: true,
            sauceConnectOpts: {
                // ...
            }
        }]
    ],
    // ...
};

If you want to use an existing Sauce Connect tunnel you only need to provide a tunnelName. If you are using a shared tunnel, and you are not the user who created the tunnel, you must identify the Sauce Labs user who did create the tunnel in order to use it for your test. Include the tunnelOwner in the capabilities like this:

export const config = {
    // ...
    {
        browserName: 'chrome',
        platformName: 'Windows 10',
        browserVersion: 'latest',
        // Sauce options can be found here https://docs.saucelabs.com/dev/test-configuration-options/
        'sauce:options': {
            tunnelName: 'YourTunnelName',

            // Example options
            build: 'your-build-name',
            screenResolution: '1600x1200',
            // ...
        },
    },
    // ...
};

export const config = {
    // ...
    {
        browserName: 'chrome',
        platformName: 'Windows 10',
        browserVersion: 'latest',
        // Sauce options can be found here https://docs.saucelabs.com/dev/test-configuration-options/
        'sauce:options': {
            tunnelName: 'TunnelName',
            tunnelOwner: '<username of owner>,

            // Example options
            build: 'your-build-name',
            screenResolution: '1600x1200',
            // ...
        },
    },
    // ...
};

Sauce Service Options

To authorize the Sauce Labs service your config needs to contain a user and key option.

maxErrorStackLength

This service will automatically push the error stack to Sauce Labs when a test fails. By default, it will only push the first 5 lines, but if needed this can be changed. Be aware that more lines will result in more WebDriver calls which might slow down the execution.

Type: number
Default: 5

sauceConnect

If true it runs Sauce Connect and opens a secure connection between a Sauce Labs virtual machine running your browser tests.

Type: Boolean
Default: false

sauceConnectOpts

Apply Sauce Connect options (e.g. to change port number or logFile settings). See this list for more information.

NOTE: When specifying the options the -- should be omitted. It can also be turned into camelCase (e.g. shared-tunnel or sharedTunnel).

Type: Object
Default: { }

uploadLogs

If true this option uploads all WebdriverIO log files to the Sauce Labs platform for further inspection. Make sure you have outputDir set in your wdio config to write logs into files, otherwise data will be streamed to stdout and can't get uploaded.

Type: Boolean
Default: true

setJobName

Allows users to dynamically set the job name based on worker parameters such as WebdriverIO configuration, used capabilities and the original suite title.

Type: Function
Default: (config, capabilities, suiteTitle) => suiteTitle

Overriding generated name metadata

The service automatically generates a name for each test from the suite name, browser name and other information.

You can override this by providing a value for the name desired capability, but this will have the side effect of giving all tests the same name.
