Haskell `堆栈测试`不返回任何结果

我已经设置了一个堆栈项目，但是当我运行

堆栈测试时，我没有得到任何输出或错误。但是，如果直接运行测试文件
runhaskell Tests.hs
，则会得到所需的结果

c:\storeCredit>stack test
storeCredit-0.1.0.0: test (suite: storeCredit-test)


c:\storeCredit>

这是我的.cabal文件：

name:                storeCredit

已解决：

问题是，在Tests.hs文件中，我有一个函数，它获取目录中的文件，并将这些文件用作测试的输入和输出。它包含以下行：

dir请添加一个。尝试
stack test-v
并将输出粘贴到此处。@Sibi我已经添加了输出matthias:正如@leftaroundabout所说，如果您还可以创建一个最小的可复制示例，这将非常有用。发布答案-这总是很有用的。即使不相关。请添加一个。尝试
堆栈测试-v
，并将输出粘贴到此处。@Sibi我已经添加了输出matthias:正如@leftaroundabout所说，如果您还可以创建一个最小的可复制示例，这将非常有用。发布答案-这总是很有用的。即使无关。
