WDIO NW.js ChromeDriver Service

(Based on wdio-chromium-service.)

---

This service helps you to run ChromeDriver shipped with the NW.js SDK seamlessly when running tests with the WDIO testrunner.

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

capabilities: [{
        browserName: 'chrome'
    }]

Installation

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

{
  "devDependencies": {
      "wdio-nwjs-chromedriver-service": "git+https://github.com/theDevelopper/wdio-nwjs-chromedriver-service.git",
  }
}

You can simple do it by:

npm install https://github.com/theDevelopper/wdio-nwjs-chromedriver-service --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 nwjs-chromedriver to your service array and you need to set the path to your NW.js ChromeDriver binary:

// wdio.conf.js
export.config = {
  port: '9515',
  path: '/',
  // ...
  services: ['nwjs-chromedriver'],
  nwjsChromeDriverPath: 'path/to/chromedriver'
  // ...
};

Configuration Example

If you want to use the NW.js SDK from npm you can install it using this command, e.g. for version 0.27.1:

npm install [email protected]

Then add the following to your wdio configuration:

// wdio.conf.js
export.config = {
  port: '9515',
  path: '/',
  // ...
  services: ['nwjs-chromedriver'],
  nwjsChromeDriverPath: 'node_modules/nw/nwjs'

  // ...
};

in this case you also need tot tell NW.js where to find your app, in our case it is in the dist dicrectory:

// wdio.conf.js
export.config = {
  capabilities: [{
        maxInstances: 1,
        browserName: 'chrome',
        chromeOptions: {
            args: ['nwapp=./dist']
        }
    }],
  // ...
};
