带有 Capybara 和 Chromedriver 的 Cucumber 测试套件挂起

Question

我有一个黄瓜测试套件，自从我搬到新电脑后，它无法运行。

测试套件使用Capybara (v1.1.2)、Chrome Driver (v26.0.1383.0) 和Selenium-Webdriver (v2.27.1) 在 Chrome 中运行 JavaScript 测试。

每次测试都会挂起 Chrome 的蓝色死亡“aw snap”。如果我用CTRL-C 终止当前测试运行，则下一个测试运行也会失败。

我完全不知所措。这个完全相同的测试套件在 Circle CI 和同事的 Mac 上运行良好。

我还尝试将 Chrome 驱动程序 换成其他 Capybara 驱动程序 Phantom JS 和 Capybara Webkit。

Phantom JS 有点被淘汰了 :(

Capybara Webkit 取得了更大的进步，但仍然未能通过许多测试：Broken pipe (Errno::EPIPE)

我认为我机器上的 Webkit 存在根本性问题。

我正在运行 Mac OS X 10.8。

有什么想法吗？

如果您仍然可以访问旧系统，您应该检查您在那里安装的 gem 的版本；

gem list --local

然后在新系统上做同样的比较。可能需要的 gem 不存在或版本错误。

如果您为测试添加 Cucumber 输出和您的 env.rb 文件，我们可能会提供更多有用的答案。
