stack repl doesn't search in test subfolder

[TimoFreiberg]

I want to write tests for different modules in separate test modules and import them in a main test file, Spec.hs.

Steps to reproduce

1. Run stack new blah and cd blah
2. Run echo "module A where" > test/A.hs
3. Run echo "import A" > test/Spec.hs
4. Run stack repl and enter :l test/Spec.hs

Expected:

Loading Spec.hs in stack repl works.

Actual:

Test modules imported in Spec.hs aren't found since the test/ directory is not in the module import search paths.

Are there workarounds other than typing :set -itest in the repl?

This is because stack ghci with no arguments means "load executable and library components", so it does not include the test dir. Try stack ghci --test.
