Stack: How to specify a subset of tests to run?

[jwaldmann]

My cabal file contains several tests. I can do cabal test Foo and it will run just this one.
What is the stack equivalent? stack test Foo does not work.

Example: https://github.com/jwaldmann/haskell-obdd

$ stack test obdd-queens
The following target packages were not found: obdd-queens

Nontrivial question. stack test means stack build --test.
Looking at stack build --help I'd try stack build --test --no-run-tests --exec obdd-queens, even though that feels a bit awkward. Does that help for now?

We should maybe have a more memorable way to do that, like stack test --suite obdd-queens.
Thoughts?

The documentation for stack's target syntax is here: https://docs.haskellstack.org/en/stable/build_command/#target-syntax

In this case the shortest command is stack test :obdd-queens.

$ stack test obdd-queens
The following target packages were not found: obdd-queens

Maybe we should provide a link to the target syntax docs in this error message?!

Ah! Maybe in the error message, more likely inside --help.

Separately, we might need a Rosetta stone for Cabal users, given that Stack's syntax is different enough.
