The tests fail on all the platforms:

I think the syntax for depending on a binary in dune is not the one you use in your test. It's something like %{bin:fake_git} or something like that.

Also note that if you depend on the exe explicitely (as oposed to the executable in general), then you might be introducing an implicit dependency to ocamlopt being available. It's not a big deal if you do, but in that case you should probably have the corresponding constraint in your opam file (making sure ocaml-option is not bytecode-only or something like that).

These tests are supposed to be part of a different package (climate_tests) which I'm not releasing. I've added a package field to the cram stanzas so these tests don't run as part of climate's tests.
