//
// This script does double-duty. It can be included from testem-electron.js
// to define an Electron test runner like so:
//
// // testem.js
// module.exports = {
//   "launchers": {
//     "Electron": require("ember-electron/lib/test-runner")
//   },
//   "launch_in_ci": [
//     "Electron"
//   ],
//   "launch_in_dev": [
//     "Electron"
//   ]
// }
//
// The runner is configured to invoke this script as a command-line executable
// with the proper arguments to run electron and communicate back to testem.
//

  exe: process.execPath,
  // These arguments are used in `lib/test-support/index.js`, which is called
  // from the test main process (via the blueprint-generated
  // `electron-app/tests/index.js`)
  args: [__filename, '<testPage>', '<baseUrl>', '<id>'],
  protocol: 'browser',
