Question

我试图在我的.cabal配置中为我的项目HaskSplit创建一个测试套件：

                       optparse-applicative >= 0.8
  hs-source-dirs:      src
  default-language:    Haskell2010
  ghc-options:         -Wall -fno-warn-orphans

test-suite tests
  type:                exitcode-stdio-1.0
  default-language:    Haskell2010
  hs-source-dirs:      tests
  main-is:             Test.hs
  ghc-options:         -Wall -fno-warn-orphans
  build-depends:       base == 4.*,
                       QuickCheck >=2.6 && <2.7,
                       test-framework-quickcheck2 >= 0.3.0.3,
                       HaskSplit

查看示例测试套件设置here，我注意到他们正在将自己的包指定为构建依赖模块之一。因此我做了同样的事情，因此我可以保留我的build-depends列表，以便我的测试套件更短。

但是，当我在命令行中尝试cabal repl test:tests时，我收到以下错误：

<command line>: cannot satisfy -package-id HaskSplit-0.1.0.0-inplace

我不太确定我在这里失踪了什么，有人可以帮帮我吗？它周围是否发生了循环依赖？或者我是否需要为构建创建我的包的库实例 - 依赖于工作？

谢谢！

Answer 1

build-depends部分只能包含库，而不能包含模块。我建议你在你的cabal文件中添加一个库。库的exposed-modules部分应列出您的测试（或库的任何其他用户）可能需要引用的所有模块。

作为创建库的替代方法，您只需将所需的模块添加到测试套件部分的其他模块部分即可。但是，如果你想要包含很多模块，我认为库方法更好。

经过一些调整之后，为了完整起见，这就是我所得到的：
