Not able to use webdriver / protractor for electron app test automation

[Jayasankar-m]

An existing angularjs was converted as electron application by following the steps in the site.
The application is working fine and it is possible to navigate through the pages.
But not able to execute automation tests with 'protractor'.

**
1.Had downloaded 'electron-chromedriver' and launched the server.'electron-chromedriver' is listening on port 9515.

2.The conf.js file for protractor is given below
**

exports.config = {
    ...
    seleniumAddress:'http://localhost:9515/',
    capabilities: {
        browserName: 'electron',
        chromeOptions: {
            binary:"<path>\\node_modules\\.bin\\electron",
            args: [" <path>"]
        },
    ...
    }
};

Following error is obtained on executing the tests.

Try defining the remote-debugging-port to 9515 as a chrome option.
