scipy: python runtest.py -t path-to-test.py failed

My issue is about running specific test in my development environnement.

Reproducing code example:

I use the command described in the doc : python runtests.py -v -t scipy/optimize/tests/test_linprog.py::test_unknown_solver --no-build

Error message:

Yes, it’s just a doc issue. A PR would be welcome. Please just change the test from test_unknown_solver to test_unknown_solvers_and_options, as the test was renamed after this documentation about running tests was written. Thanks!

Ah, I see what happened (to me, anyway–I’m not sure this helps @V0lantis). My attempt to use file paths failed because I used -n, and I am not using an in-place build (i.e. I first ran python setup.py install). To use -t with a file path, I would need to give the path to the installed file, which is in the site-packages/scipy directory of the current Python installation.

So one can use file paths or Python names. (I don’t see a reason to prefer either one, except perhaps for the case that I ran into.)

It looks like there is a mistake in those docs

File paths work (at least one Windows and Mac), although it’s nice to know that Python names work, too. Are Python names preferred?

<strike>It looks like there is a mistake in those docs. The argument to the -t option should be a Python name (i.e. a dotted Python module path), not a file path</strike> Update: see comments below.

And as @ilayn pointed out, the test that you were trying to run no longer exists.

This works for me:

$  python runtests.py -v -n -t scipy.optimize.tests.test_linprog::test_unknown_solvers_and_options

::test_unknown_solver is not an actual test because apparently it has been renamed

https://github.com/scipy/scipy/blob/master/scipy/optimize/tests/test_linprog.py#L232

It is just an example anyways so feel free to pickup any other test.
