[SciPy-User] Hacking scipy and running the tests

[Lars Buitinck]

Hi all,

I've submitted several patches to Scipy so far, am I've hit this
problem every time: you can't import Scipy from within the source dir,
so you can't run the tests without building and installing. But that
takes a long time, and then when you edit a file, you either have to
edit it in the installation and not forget to copy it back (without
help from Git), or you must rebuild and reinstall.

Is there a smarter way to do all this? How do the Scipy core developers do this?

TIA,
