- Nobody (human, software, ...) is gonna execute *accidentally* the tests
in a production server (e.g. running server will not wait until
3h test run to acquire global lock or connection ...)
- Space is preserved . That's something important if talking about
using the package in constrained environments (e.g. limited devices,
shared hosting, ...) . This also makes me recall decisions like
splitting stdlib in order to build custom (as small as possible,
yet functional) installers for Python itself.
- Python test suite is *optionally* installed -at least in Windows-,
isn't it ?
So it seems it's worth it for all packages in stdlib under certain
- It's always possible to install the test package at any time and do
whatever with it , as well as remove it later.

Yes definitely , but I'd say complex (since «complex is better than

Well, «practicality (will always) beat purity» (and that's why I first
mentioned that I'd like to do something like this , but currently I
don't 'cause, in practice, I've not had the time to think about how to
do it «perfect» & easy ;o) .
PS: I understand that probably there's not a universal solution for
all kind of packages .
