我已经设置了堆栈项目但是当我运行stack test时，我没有得到任何输出或错误。但是，如果我直接运行测试文件runhaskell Tests.hs，我会得到我想要的结果。
c:\storeCredit>stack test
storeCredit-0.1.0.0: test (suite: storeCredit-test)
c:\storeCredit>
这是我的.cabal文件：

解决：
问题是在我的Tests.hs文件中，我有一个函数可以获取目录中的文件并将其用作输入和输出进行测试。它包含以下行：
dir <- getDirectoryContents =<< getCurrentDirectory
如果使用与Test.hs文件相同的目录（即\test）运行，这显然很好。这就是runhaskell Test.hs有效的原因。但是，stack test从父文件夹运行到test，我不得不更改正在读取的路径。
改为：
dir <- getDirectoryContents =<< ((++ "\\test") <$> getCurrentDirectory)
修复了问题
