[IPython-dev] Unit testing

[Brian Granger]

Ville,

Fernando knows much better about how nose finds tests, but I think in
this case I know what the issue is.  Nose only looks for tests in
modules names *test*.py.  We are putting such files in locations like

IPython.tests
IPython.kernel.tests
IPython.frontend.tests
etc.

Broadly speaking, any package should have a tests sub-directory that
has test modules for each module in the package:

foo.py
bar.py
tests
    test_foo.py
    test_bar.py

If you then go put your unittests or nose tests in test_foo.py or
test_bar.py nose should pick them up automatically.

The tests for the ipy_profile_sh.py module would probably go into

IPython.tests.test_profile_sh.py

Does that help?  Fernando, any other wisdom as to how nose finds tests?

We need to update our Sphinx developer docs about this.

Cheers,

Brian
