Haskell Stack Ghci test-suite

Question

I\'m trying to use stack to load my test-suite in ghci and have it load the QuickCheck and hspec dependency.

How can I do this?

I\'m using the franklinchen templ

Answer 1

stack ghci --test

Note that this will only work if there's a single test suite and no other executable. Otherwise it will give you a warning:

* * * * * * * *
The main module to load is ambiguous. Candidates are:
Package `project' component exe:project-exe with main-is file: T:\project\app\Main.hs
Package `project' component test:project-test with main-is file: T:\project\test\Spec.hs
None will be loaded. You can specify which one to pick by:
 1) Specifying targets to stack ghci e.g. stack ghci project:exe:project-exe
 2) Specifying what the main is e.g. stack ghci --main-is project:exe:project-exe
* * * * * * * *

In this case you have to use

stack ghci --test chapterexercises:test:spec

Without --test stack is going to ignore the tests. That's why you don't get the ambiguity error in the first place.
