test.libregrtest is not installed, which breaks running of test suite from installed Python.
Probably LIBSUBDIRS in Makefile.pre.in should be updated.

$ python3.5 -m test test_int
[1/1] test_int
1 test OK.
$ python3.6 -m test test_int

Hum, not only libregrtest was not installable, but test_regrtest didn't work on installed Python.

Can you please retry?

It would be nice to modify test_regrtest to *not* write into the test package, but I failed to find a way to load tests from a different directory :-/

It used to be there were also changes that needed to be made to the windows build files when a new directory was added. Nosying Steve in case this is still true, assuming there is an option to install the tests (which there might not be, I have no idea not being a Windows user).

I failed to find other test subdirectories in PCbuild/ :-/ I don't
think that tests are installed or installable on Windows.

Thanks. For 3.5 and later we automatically grab Lib//* (except *.py[co]), with Lib/test//* split out into a separate install option.

I disliked the manual updating as much as everyone else did :)

[bitdancer]

Thanks for doing that, Steve. It would be lovely to fix the unix make too, but I'm sure there's a reason why it is currently done the way it is done and I don't feel like figuring out why so as to try to make things better :)

[zooba]

@victor - is there anything else to be done for this issue or can we close it?

[vstinner]

Please close the issue.
