我正在研究 Ubuntu 15.04:
平台linux -- Python 3.4.3, pytest-2.8.3, py-1.4.31, pluggy-0.3.1
rootdir: /home/barrios/code/testpytest, inifile:
在一个新的 virtualenv 中，我构建了以下项目结构：
myapp/
__init__.py
myapp.py
tests/
tests.py
setup.py
按照这里的各种帖子，我发现要么将 PYTHONPATH 设置为我的项目根目录，要么使用以下方式调用 py.test：
PYTHONPATH=. py.test tests/tests.py
myapp.py 看起来像这样：
class Foo:
def __init__(self):
self.bar = None
def set_bar(self, val):
self.bar = val
tests.py:
from myapp import Foo
class TestFoo:
def setup_method(self, method):
self.foo = Foo()
def teardown_method(self):
self.foo.bar = None
def test_set_bar(self):
self.foo.set_bar(7)
assert self.foo.bar is 7
阅读我也把这个放在我的__init__.py:
from .myapp import Foo
__all__ = ['Foo']
我能做到
>>> from myapp import Foo
在 python 控制台和
$> pip install -e .
来自终端。
但是 py.test 抱怨引发内部错误：
