WebdriverIO Gmail Service

A WebdriverIO plugin to fetch e-mails from Google Mail using Gmail Tester.

Installation

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

{
  "devDependencies": {
    "wdio-gmail-service": "^2.0.0"
  }
}

You can simply do it by:

npm install wdio-gmail-service --save-dev

Usage

Gmail Authentication

You'll need to follow the instructions at Gmail Tester to create the credentials.json (the OAuth2 Authentication file) and token.json (the OAuth2 token).

Configuration

Add the service by adding gmail to the service list, e.g.:

// wdio.conf.js
import path from 'path'

export const config = {
    // ...
    services: [['gmail', {
        credentialsJsonPath: path.join(process.cwd(), './credentials.json'),
        tokenJsonPath: join(process.cwd(), './token.json'),
        intervalSec: 10,
        timeoutSec: 60
    }]]
    // ...
};

        const emails = await browser.checkInbox({ from: 'AccountSupport@ubi.com', subject: 'Ubisoft Password Change Request' });
