After cloning and installing (I believe in the proper way - I followed this tutorial) I go to to ~\Cucumber\Cucumber\cpp\examples\Calc and type cucumber --init.

I get 

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)

While I understand this is a basic mistake I really could not find a solution for this. I visited most links that show up when I type it in google.
My questions are:
- I am working on a network, would that cause issues with the wiring?
- Are there any extra steps required to run the example? The documentation mentions CMake but I did not find its usage
- What other issues might cause this?
- Could you point me to any good tutorial to getting started with cucumber-cpp? (written only)

This computer is a Windows 7 Professional

EDIT:
If I use the given port in the wire file I get: 

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)

I also could not fix this based on any of the information I found.

答案：

  • Windows 上的防火墙可能会导致问题，但通常您会看到一个请求确认访问的弹出窗口（您也可以尝试暂时禁用防火墙以验证是否存在问题）。
  • 是的，虽然缺乏很好的解释，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好的起点（确保您遵循所有步骤）。不幸的是，没有很好的文档。

Cucumber-CPP 当前的工作方式是让 Cucumber-Ruby 连接到 C++ 实现正在侦听的 TCP 端口。当文件中定义了有线协议cucumber.wire，以及 C++ 有线协议服务器正在侦听的主机和端口时，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和它们使用的所有内容（通常是被测应用程序），创建一个可执行文件，该文件将侦听localhost:3902Cucumber-Ruby 连接到的有线协议端口（默认为 ）（和断开时退出）。
