Cucumber-cpp required software for running example

本文关键字：软件 运行 Cucumber-cpp      更新时间：2023-10-16

克隆和安装后(我相信正确的方式 - 我遵循了本教程(，我转到~CucumberCucumbercppexamplesCalc并键入cucumber --init。

我得到

C:CucumberCucumber-cppexamplesCalc>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)

虽然我知道这是一个基本错误，但我真的找不到解决方案。我访问了在谷歌中输入时显示的大多数链接。
我的问题是： -
我正在网络上工作，这会导致接线问题吗？
- 运行示例是否需要任何额外步骤？文档提到了 CMake，但我没有找到它的用法 -
还有哪些其他问题可能导致这种情况？
- 你能指出我任何开始使用黄瓜-CPP 的好教程吗？(仅书面(

此计算机是 Windows 7 专业版

编辑：如果我在线路文件中使用给定的端口，我会得到：

C:CucumberCucumber-cppexamplesCalc>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此问题。

答案：

  • Windows 上的防火墙可能会导致问题，但通常您会看到一个弹出窗口，请求确认访问(您也可以尝试短暂禁用防火墙以验证这是否是问题(。
  • 是的，虽然缺乏很好的解释，但项目的自述文件中定义的步骤应该是正确的。
  • 不使用C++步骤定义启动线路服务器。
  • 项目存储库中的指南可能是最佳起点(请确保遵循所有步骤(。不幸的是，不是很好的文档。

Cucumber-CPP 目前的工作方式是让 Cucumber-Ruby 连接到 TCP 端口，C++ 实现正在侦听该端口。当在cucumber.wire文件中定义线路协议时，主机和端口是C++线路协议服务器正在侦听的，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，如自述文件中所述。Cucumber-CPP 需要链接到步骤定义和它们使用的所有内容(通常是被测试的应用程序(，创建一个可执行文件，该文件将侦听 Cucumber-Ruby 连接的线路协议端口(默认为localhost:3902(以连接(并在断开连接时退出(。
