WDIO GeckoDriver Service

This service helps you to run GeckoDriver seamlessly when running tests with the WDIO testrunner. This service does not require a Selenium server, but uses the geckodriver NPM package that wraps the GeckoDriver for you or uses a global installed binary.

Example capabilities:

capabilities: [{
    browserName: 'firefox'
}]

Installation

npm install wdio-geckodriver-service --save-dev

Configuration

By design, only Firefox is available (when installed on the host system). In order to use the service you need to add geckodriver to your service array:

// wdio.conf.js
export.config = {
    // MANDATORY: Add geckodriver to service array.
    // Default: empty array
    services: [
        [
            'geckodriver',
            // service options
            {
                // The path where the output of the Geckodriver server should
                // be stored (uses the config.outputDir by default when not set).
                outputDir: './logs',

                // pass in custom options for Geckodriver, for more information see
                // https://github.com/webdriverio-community/node-geckodriver#options
                geckodriverOptions: {
                    log: 'debug' // set log level of driver
                }
            }
        ]
    ],
};
