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

Question

我正在使用webdriverjs在Windows 8上运行自动化测试。当我将浏览器设置为Chrome时，测试工作正常，但是当我使用PhantomJS时，测试工作正常。当我在OS X Mavericks上运行它们时，相同的测试也能正常工作。

测试不会失败，他们只是无限期地等待。

以下是定义客户端的文件：

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

这是包含我的测试的文件：

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);
  });
});

我在全球安装了mocha，selenium-standalone和phantomjs NPM软件包，并在项目目录中安装了webdriverjs和chai。

我使用start-selenium命令启动selenium，然后使用mocha test.js执行我的测试。

如上所述，测试不会失败，只是等待闪烁的光标，直到我强行退出。

以下是selenium的输出：

Answer 1

Ghostdriver需要注册Selenium服务器：

（1）启动Selenium服务器作为集线器：

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

（2）启动phantomjs / ghostdriver并将其注册到selenium服务器

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

如果没有Selenium服务器，有open webdriverjs issue阻止直接使用phantomj。
