node.js - Protractor 在 PhantomJS 上运行测试

Question

我似乎无法通过测试成功获得 PhantomJS。我试图将它集成到我的项目中，但在那之后我尝试只运行基本的 Angular Docs 示例并且我遇到了同样的问题。到目前为止我的步骤:

• npm install -g phantomjs
• phantomjs --webdriver=9515//... GhostDriver - Main - 在端口 9515 上运行
• Protractor protractorConf.js

这与示例中的文件相同，只有 browserName 和 seleniumAddress 端口已更改:

// An example configuration file.
exports.config = {
  // The address of a running selenium server.
  seleniumAddress: 'http://localhost:9515',

  // Capabilities to be passed to the webdriver instance.
  capabilities: {
    'browserName': 'phantomjs'
  },

  // Spec patterns are relative to the current working directly when
  // protractor is called.
  specs: ['onProtractorRunner.js'],

  // Options to be passed to Jasmine-node.
  jasmineNodeOpts: {
    showColors: true,
  }
};

我收到以下错误消息:

UnknownError: Error Message => 'Detected a page unload event; asynchronous script execution does not work across page loads.'

我找到了 this issue on github ，这似乎是相关的。我以为我已经对他们的brower-setup.md 有了足够的了解。将其包含在我的 beforeEach 函数之一中。然后我找到了here ptor 无论如何只是包装驱动程序。哇，我知道我是 Protractor/ Selenium 领域的菜鸟，但信噪比非常具有说服力。我真的很想获得使用 PhantomJS 的性能优势，但是为此多花几个小时的前景让我很头疼。我使用的是 Windows 7 Enterprise 64 位，以防万一。谢谢!

在 protractor/lib/protractor.js 里面替换

this.driver.get('about:blank');
this.driver.executeScript(
    'window.name = "' + DEFER_LABEL + '" + window.name;' +
    'window.location.href = "' + destination + '"');

与

  var driver = this.driver;
  this.getCapabilities().then(function (capabilities) {
    if (capabilities.caps_.browserName === 'phantomjs') {
      driver.executeScript('window.name = "' + DEFER_LABEL + '" + window.name;');
      driver.get(destination);
    } else {
      driver.get('about:blank');
      driver.executeScript(
          'window.name = "' + DEFER_LABEL + '" + window.name;' +
          'window.location.href = "' + destination + '"');
    }

    // Make sure the page is an Angular page.
    driver.executeAsyncScript(clientSideScripts.testForAngular, 10).
      then(function(hasAngular) {
        if (!hasAngular) {
          throw new Error('Angular could not be found on the page ' +
              destination);
        }
      });
  });
