py.test - How are python module paths translated to filesystem paths? -

-

this may seem simple question, haven't found answer explains behavior i'm seeing. hard provide simple repro case have package structure this:

a.b.c a.b.utils

i have 1 project has files in a.b.c. (let's call aux_project) , has files in a.b.d, a.b.utils, etc (call main_project). i'm trying import a.b.utils inside pytest tests in first project, using tests_require. not work because a.b reason sourced inside aux_project/a/b/__init__.pyc instead of virtualenv , shadows other package (i.e. a.b has c in it, not d or utils). happens in test context. in ipython can load packages fine, , correctly loaded virtualenv.

what's weirder if delete actual directory, tests load pycs virtualenv , works (i need directory, though)

python==2.7.9

what going on?

ok, problem cwd prepended pythonpath. sys.path.pop(1) (0 tests dir, prepended pytest) resolved behavior.
