python - What constitutes a package for nosetests? -

i've written "package" -- mean directory __init__.py in -- called ardid:

(master)dbliss@nx3[ardid]> ls analysis.py   ardid.sh     __init__.pyc    plot_support.py   utils.py analysis.pyc  goals.py     k_12.png        plot_support.pyc  utils.pyc ardid.py      goals.pyc    plot_ardid.py   results/ ardid.pyc     __init__.py  plot_ardid.pyc  tests/ 

as can see, package contains following modules

• analysis
• ardid
• goals
• plot_ardid
• plot_support
• utils

as test modules in directory tests.

(__init__.py empty.)

however, when run nosetests --cover-package=ardid, output shows coverage few of ardid's modules (specifically ardid, goals, , utils):

(master)dbliss@nx3[ardid]> nosetests tests -s --cover-package=ardid --with-coverage ............... name             stmts   miss  cover   missing ---------------------------------------------- ardid.py             0      0   100%    ardid/ardid.py     108     54    50%   105-254 ardid/goals.py      42     38    10%   52-87, 102-161 ardid/utils.py     437    366    16%   23-26, 30-71, 78, 83-89, 108-110, 113-140, 142-146, 165-166, 168-183, 186-218, 223-285, 288-324, 344, 357-427, 438-441, 443-444, 446-468, 475-480, 483-496, 499, 508-509, 512-513, 516-524, 532, 545-548, 559, 571, 575-576, 581-582, 594-605, 614-615, 618-1018 ---------------------------------------------- total              587    458    22%    ---------------------------------------------------------------------- ran 15 tests in 11.454s  ok 

why this?

note not case these modules have tests:

(master)dbliss@nx3[ardid]> ls tests/ test_plot_support.py  test_plot_support.pyc  test_utils.py  test_utils.pyc 

what true ardid module imports goals , utils, not import other modules. what's causing nosetests detect goals , utils (in addition ardid)? why be?

i think answer may have way i'm importing package modules in test modules. because ardid module has same name package, have import with

from ardid import ardid 

(if call simply

import ardid 

the package imported.)

the other modules import with, e.g.,

import utils 

nosetests considers part of package ardid modules imported ardid (from ardid package, not module).

thus, 1 simple solution change imports in test modules to

from ardid import x 

where x 1 of modules tested.

another solution, more appropriate if package intended use other me (and subsumes solution), provided @jonrsharpe in comments.
