[Caml-list] How to test a repository using OPAM?

[Malcolm Matalka]

I'm setting up testing infrastructure for some of my repositories and
I'm running into a bit of an issue.  My setup looks like:

1. Update the standard opam-repository

2. Upgrade any dependencies (I want to know if I break against the
bleeding edge

3. Automatically generate an OPAM package for my repository.

4. opam install --deps-only -t my-package

5. make tests

The -t is in step 4 because I need the testing dependencies for
my-package in order to run the tests.  The problem I have is that the -t
runs the tests for all packages it installs.  I tried doing the install
in two steps, the first without the -t and the second with, but that
doesn't solve the problem because it installs testing libraries for all
deps and runs those tests.  In my case, I depend on Ctypes which depends
on Lwt for testing and the Lwt tests take far too long.

Is there a way to tell opam to only install the testing libraries needed
to test but to not test?  On top of that, can I tell it to only install
the testing libraries needed for the package I want to install and not
its dependencies?

Thanks,
/Malcolm

I can't find where, but recently it was mentioned that the recursive
application of -t is an obvious mistake. So I'm guessing this is already
resolved in the latest opam.
