ChromeDriver Service

> wdio-chromedriver-service is a 3rd party package, for more information please see GitHub | npm

(Based entirely on wdio-selenium-standalone-service.)

Note: If you're working with WebdriverIO v6, use version 6.X.X\ If you're working with WebdriverIO v5, use version 5.X.X\

This service helps you to run ChromeDriver seamlessly when running tests with the WDIO testrunner. It uses the chromedriver NPM package that wraps the ChromeDriver for you.

Note - this service does not require a Selenium server, but uses ChromeDriver to communicate with the browser directly. Obvisously, it only supports:

capabilities: [{
browserName: 'chrome'
}]

Installation

The easiest way is to keep wdio-chromedriver-service as a devDependency in your package.json.

{
"devDependencies": {
"wdio-chromedriver-service": "^6.0.0"
}
}

You can simple do it by:

npm install wdio-chromedriver-service --save-dev

Note! You have to install chromedriver separately, as it's a peerDependency of this project, and you're free to choose what version to use. Install it using:

npm install chromedriver --save-dev

Instructions on how to install WebdriverIO can be found here.

Configuration

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

// wdio.conf.js
export.config = {
outputDir: 'all-logs',
// ...
services: [
['chromedriver', {
outputDir: 'driver-logs', // overwrites the config.outputDir
args: ['--silent'] //
}]
],
// ...
};
