Applied, thanks!

I noticed this program and some of the libraries it uses, requires a
package called "CoverageTestRunner" to run unit tests. Currently tests
are simply skipped.

It would be nice to have that package in Guix too. Tests helps us
discover problems early, such as incompatible versions etc.

Would you be willing to package it? For "obnam", the 'check' phase
needs to be replaced by a phase that calls "./check" afterwards:

       #:phases
       (modify-phases %standard-phases
         (replace 'check
           (lambda _ (zero? (system* "./check")))))))

Anyway, pushed to 'master' as a2fa9c3d1baf65cc5aec2ce843e2d7921e593c21.

I tried packaging the tests too. But, the tests require the root user
and group to be present. The build environment does not have the root
user and group. So, the tests fail. Can anything be done about this? Or
should I abandon packaging the tests, and just mention this in the
comments somewhere?

I also tried running the tests in my own user environment, and they ran
fine.

There is one user available in the build environment: "nobody". It could
work to substitute "root" for "nobody" in the code that looks for users.
The "mailutils" package does exactly that for tests. Can you try it?

TIA!

Yes, I'll try to get the tests working, and let you know.

I've sent patches for this to guix-patches@gnu.org.
