Chrome浏览器版本42.0.2311.152 m(64位)-在量角器自动测试中不允许在浏览器上查看pdf

Question

新版Chrome浏览器不包括- mine type - application/pdf(当通过量角器运行时)，这将允许我在浏览器上查看pdf并通过量角器测试url，但它会自动下载并关闭选项卡。如果你手动打开chrome并点击链接，它会在下一个标签中打开pdf，而不会自动下载。

手动运行chrome有以下扩展名::

Chrome自动化扩展-由Protractor运行(MIME类型-这里缺少application/pdf扩展，允许浏览器在浏览器上查看pdf在chrome自动扩展上通过量角器直接连接浏览器运行)

在chrome上有一个类似的问题，但还没有解决方案: https://productforums.google.com/forum/#!主题/铬/A3XrBbHD80U

如果您不关心测试运行时的警告消息，那么这应该可以工作:

"desiredCapabilities": {
    "chromeOptions": {
      "excludeSwitches": [ "test-type" ]
    }
  }
