Electron app with protractor end-to-end testing - angularjs

Question

I'm currently working on an Electron app and I now want to integrate end-to-end testing with Protractor. I've reviewed the tutorials for Protractor and am now trying to adapt it to Electron. Since Electron runs as a standalone app, how do I do this?
It seems that Protractor stands-up a Selenium server that then tries to reach out to an available HTTP server and run tests such as click here, what url am I on, input this text, etc.
Therefore how would I go about allowing the selenium server access to the electron instance?
Anyway that's my mindset on the situation, any help is appreciated and feel free to correct any of my assumptions.

Answer 1

Adapting the instructions documented at Using Selenium and WebDriver, here is what you need to put into your protractor config (using directConnect, as an example):
exports.config = {
directConnect: true,
capabilities: {
browserName: "chrome",
chromeOptions: {
binary: '/Path-to-Your-App.app/Contents/MacOS/Atom' // < IMPORTANT!
},
},
// ...
}
(not tested)

Answer 2

alecxe's answer is mostly correct, but there's one slight inaccuracy with it.
binary should be nested under chromeOptions like so:
exports.config = {
directConnect: true,
capabilities: {
browserName: "chrome",
chromeOptions: {
binary: '/Path-to-Your-App.app/Contents/MacOS/Atom' // < IMPORTANT!
}
},
// ...
}
