how to run a Hspec test suite

[pcarbonn]

I checked #128, but it does not fully solve the problem.

When I run ghcid "--command=stack ghci H-Calc:spec" "--test=:main", it runs my test set correctly, and again correctly when I change the code of my test suite, but NOT if I change the code of my main project.

Ghcid seems to track the test folder, but not the src folder.

My project is on github, so you can see the file structure and cabal file.

OK. Thanks !

Is there a solution for this with cabal as well?

ghcid --command='cabal v2-repl lib:orgmode-parse test:tests' --test 'Main.main'
Loading cabal v2-repl lib:orgmode-parse test:tests ...
cabal: Cannot open a repl for multiple components at once. The targets
'orgmode-parse' and 'tests' refer to different components..

The reason for this limitation is that current versions of ghci do not support
loading multiple components as source. Load just one component and when you
make changes to a dependent component then quit and reload.

Command "cabal v2-repl lib:orgmode-parse test:tests" exited unexpectedly with error message:

The underlying issue is a limitation in GHC, which is being addressed by a summer-of-code project as we speak. Cabal chooses to take that limitation and make it a fatal error. Stack chooses to continue, accepting things might not work. But I don't believe there's much to be done with Cabal, other than talking to the Cabal maintainers, or waiting for a GHC with multi-component support.

is there any progress by now?

The work has not been completely merged, but stepping stones written by @fendor and also @hsyl20 have. Rest assured we will get there!

Just checking in. Is there a workaround/solution for cabal repl that I missed somehow?

[ndmitchell]

@sekunho - if you are referring to the issue of loading src and test at once, then I don't think it's fully merged yet, but I'm not sure.

This is now possible with cabal-head, e.g. for ghcup:

ghcup install cabal -u https://github.com/haskell/cabal/releases/download/cabal-head/cabal-head-Linux-x86_64.tar.gz head

until haskell/cabal#8726 makes into a release (probably 3.12 from the milestones).

This allows something like:

ghcid --command='cabal v2-repl --enable-multi-repl test:tests lib:orgmode-parse' --test 'Main.main'
