+description: """
+opam-test: similar to opam-build, this will setup a local switch and install all the required dependencies, but will also run the tests on top of it. It also circumvents issues with cyclic test dependencies in opam (where the tests require a package that needs the library it is trying to test). Such cyclic dependency is present in packages such as odoc or base. See https://github.com/ocaml/opam/issues/4594
