Can't run Selenium via Protractor on Firefox a

Question

After updating Angular JS 1.4.x to Angular 2, Selenium tests can't run anymore via grunt-protractor-runner on Firefox. As soon as AngularJS is loaded, the following error occurs:

D:\...\node_modules\grunt-protractor-runner\node_modules\protractor\node_modules\selenium-webdriver\lib\atoms\error.js:108
  var template = new Error(this.message);

Chrome and Internet Explorer work fine.

The problem appears with the following components:

• Firefox version 38 and 42
• grunt-protractor-runner 2.1.0 and 3.0.0 (which uses selenium-server-standalone-2.48.2.jar)
• protractor 2.5.1 and 3.0.0

The following node modules are in use (package.json):

{
  "name": "...",
  "version": "1.0.0",
  "description": "",
  "main": "Gruntfile.js",
  "dependencies": {
    "jasmine-reporters": "^2.0.7",
    "protractor-video-recorder": "^0.1.0"
  },
  "devDependencies": {
    "grunt-protractor-runner": "^3.0.0",
    "jasmine-spec-reporter": "^2.4.0",
    "lodash": "^3.10.1",
    "protractor-console": "^2.0.0"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

There is no code part in the Selenium test, which can be localized to produce the error. The error appears just at the moment when AngularJS is loaded.

Answer 1

To isolate the problem I installed the sample Angular 2 Go with Protractor ! and got exactly the same error (as in my first comment) after I changed browserName: 'chrome' to firefox.

Thus I created a new issue on Protractors github page.

Answer 2

See related tickets:

• https://github.com/angular/protractor/issues/2784
• https://github.com/SeleniumHQ/selenium/issues/1416

Based on the last comment on the selenium ticket:

Angular 2 is patching EventTarget.prototype, so they are responsible for any bugs caused by their changes.
