Path configuration for testing Ember-electron with Spectron

Question

I am trying to integrate Spectron with Ember-electron for testing.

I found an example for Spectron but I am not sure what to assign in the electronPath part in case of Ember-electron.

I do not have an .exe or .cmd how to point to the location of the application in the test folder.

beforeEach(function () {
return helpers.startApplication({

  args:[path.join(__dirname, '..')] //**
}).then(function (startedApp) { app = startedApp })
})
