在Windows上使用PhantomJS时，We​​bdriverJS测试会挂起

Question

I'm using webdriverjs to run automated tests on Windows 8. The tests work correctly when I set the browser to Chrome but not when I use PhantomJS. The same tests also work correctly when I run them on OS X Mavericks.

The tests don't fail, they just wait indefinitely.

Here is the file where the client is defined:

exports.client = require('webdriverjs').remote({
  desiredCapabilities: {
    browserName: 'phantomjs'
  }
});

Here is the file containing my test:

var chai        = require('chai'),
    assert      = chai.assert,
    expect      = chai.expect,
    webdriverjs = require('webdriverjs'),
    client      = require('./client').client;

describe('my webdriverjs tests', function(){

  this.timeout(10000);

  before(function(done){
    client.init(done);
  });

  it('Github test',function(done) {
    client
      .url('https://github.com/')
      .getElementSize('.header-logo-wordmark', function(err, result) {
        assert.equal(null, err);
        assert.strictEqual(result.height , 32);
        assert.strictEqual(result.width, 89);
      })
      .getTitle(function(err, title) {
        assert.equal(null, err);
        assert.strictEqual(title,'GitHub · Build software better, together.');
      })
      .getCssProperty('a[href="/plans"]', 'color', function(err, result){
        assert.equal(null, err);
        assert.strictEqual(result, 'rgba(65,131,196,1)');
      })
      .call(done);
  });

  after(function(done) {
    client.end(done);
  });
});

I have the mocha, selenium-standalone and phantomjs NPM packages installed globally, with webdriverjs and chai installed in the project directory.

I start selenium using the start-selenium command and then execute my test using mocha test.js .

As mentioned, the test doesn't fail, it just waits with a blinking cursor until I force it to exit.

Here is the output from selenium:

Answer 1

Ghostdriver needs to register with the Selenium server:

(1) start the Selenium server as a hub:

java -jar selenium-server-standalone-2.42.2.jar -role hub

(2) start phantomjs/ghostdriver and register it with the selenium server

phantomjs --webdriver=4445 --webdriver-selenium-grid-hub=http://127.0.0.1:4444

There is an open webdriverjs issue preventing direct use of phantomjs without the Selenium server.
