我正在Haskell中编写一个小型库，并希望进行测试。为了进行测试，我打算使用HFT，整个项目由堆栈管理。 stack test由于某些原因而失败，并显示以下输出：
[1 of 2] Compiling Main ( test/Ini.hs, .stack-work/dist/x86_64-linux-tinfo6/Cabal-2.0.1.0/build/ini-tests/ini-tests-tmp/Main.o ) │····························

稍后将包含测试的我的Ini.hs文件非常准，
import Test.Framework
main :: IO ()
main = htfMain htf_thisModulesTests
我的package.yaml是

这是自动生成的schemer.cabal：

我不确定这是什么问题以及Paths_schemer的问题是什么。感谢您的帮助。
答案 0 :(得分：1)
-F -pgmF htfpp选项已全局打开。这会将HTF预处理程序应用于测试套件的所有文件，包括自动生成的Paths_schemer。
更具可扩展性的解决方案是使用每个文件中的Test.Framework编译指示，仅对导入OPTIONS_GHC的文件启用预处理器：
{-# OPTIONS_GHC -F -pgmF htfpp #-}
另一种方法是在other-modules: []的test-suite部分中设置package.yaml以避免生成Paths_schemer，尽管这只能解决该模块的问题。
