Question

克隆和安装后（我相信正确的方式 - 我跟着this tutorial），我转到~\Cucumber\Cucumber\cpp\examples\Calc并输入cucumber --init。

我得到了

C:\Cucumber\Cucumber-cpp\examples\Calc>cucumber --init
  exist   features
  exist   features/step_definitions
  exist   features/support
  exist   features/support/env.rb
  Timed out calling wire server with message 'step_matches' (Timeout::Error)

其次是

虽然我知道这是一个基本错误，但我真的找不到解决方法。当我在google中输入时，我访问了大多数显示的链接我的问题是：
- 我正在网络上工作，这会导致布线问题吗？ - 运行该示例是否需要额外的步骤？ documentation提及CMake，但我没有找到它的用法 - 还有哪些其他问题？ - 你能指点我开始使用cucumber-cpp吗？（仅限书面）

此计算机是Windows 7专业版

编辑：
如果我在wire文件中使用给定的端口，我得到：

C:\Cucumber\Cucumber-cpp\examples\Calc>cucumber --init
   exist   features
   exist   features/step_definitions
   exist   features/support
   exist   features/support/env.rb
Unable to contact the wire server at localhost:3902. Is it up? 
(Cucumber::Wire::Connection::ConnectionError)

我也无法根据我找到的任何信息解决这个问题。

数目：

Windows上的防火墙可能会导致问题，但通常会看到弹出窗口请求确认访问权限（您也可以尝试暂时禁用防火墙以验证是否存在问题）。
是的，虽然缺乏良好的解释，但项目README中定义的步骤应该是正确的。
未使用C ++步骤定义启动有线服务器。
项目存储库中的指南可能是最佳起点（确保您遵循所有步骤）。不幸的是，没有很好的文档。

Cucumber-CPP目前的工作方式是让Cucumber-Ruby连接到C ++实现正在监听的TCP端口。当在cucumber.wire文件中定义有线协议时，使用C ++有线协议服务器正在侦听的主机和端口，Cucumber-Ruby将尝试使用Cucumber-CPP运行它们。

C ++是一种编译语言，因此必须首先编译步骤定义。提供的示例使用CMake，如README中所述。 Cucumber-CPP需要链接到步骤定义及其使用的所有内容（通常是测试中的应用程序），创建一个可执行文件，该文件将监听Cucumber-Ruby的有线协议端口（默认为localhost:3902）连接（并在断开连接时退出）。
