discover should ignore build/ and dist/ by default

[mikofski]

If running py.test from same folder as setup.py then test discovery may enter build/ causing errors. Removing the build/ directory, using --ignore=build and setting norecursedirs for [pytest] in any .ini file all solve the issue, but can py.test be configured to always ignore this folder? Note nose2 and nosetests do not have this issue.

In the case where dynamic module import occurs and the path is specified relative to the test directory, then py.test returns the following stacktrace:

___________ ERROR collecting build/lib/circus/tests/test_outputs.py ___________
c:\python27\lib\site-packages\py\_path\local.py:650: in pyimport
    __import__(modname)
build\lib\my_package\tests\test_this.py:8: in <module>
    fid, fn, info = imp.find_module(MODULE, [PACKAGE])
E   ImportError: No module named dynamic_module

minimalist example

my_package -> tests -> test_this.py

import os
import imp

MODULE = 'dynamic_module'
PACKAGE = os.path.join('path', 'to', 'package', 'of', 'dynamic_module']

# use imp to find and load dynamic module
fid, fn, info = imp.find_module(MODULE, [PACKAGE])
my_module = imp.load_module(MODULE, fid, fn, info)
fid.close()
