Hi Martin,

thanks for your quick answer.

Except that I run a shell script where I execute python scripts and I just
want to ensure that they work... in my case /usr/bin/django-admin has some magical
code to figure out whether python3 is available or not and run the right
script with the right interpreter. So would something like this be
accepted?

    Test-Command: debian/tests/django-admin
    Depends: python-django

    Test-Command: debian/tests/django-admin
    Depends: python3-django

I assumed that it was not ok because you would have no way to
differentiate between both tests... but I guess that I could add
a fake unused parameter to differentiate them.

You might also want to improve the description of the Test-Command
field in README.package-tests to make this use-case more explicit, I
mainly skipped it because it was advertised to run pre-existing test
scripts from upstream and such.

That was not my use case, I run plain shell scripts. In a second test,
I just used the python interpreter to run the upstream test suite after
having copied it to $ADTTMP.

See http://anonscm.debian.org/cgit/python-modules/packages/python-django.git/tree/debian/tests/test-suite

Looks like it's enough for my needs, yes, but documenting this use case
would be most welcome.
