Question

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

在这里发表各种帖子后，我发现要么将PYTHONPATH设置为我的项目根目录，要么调用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this post我也把它放在__init __。py：

中

from .myapp import Foo

__all__ = ['Foo']

我能够做到

>>> from myapp import Foo

在python控制台和

$> pip install -e .

来自终端。

但是，py.test抱怨抛出一个内部错误：

我不太相信在py.test bugtracker上报告一个问题，或者我是否仍然做错了什么？

您的拆解方法缺少第二个参数，即method：

def teardown_method(self, method):

仔细阅读文档： https://pytest.org/latest/xunit_setup.html

py.test INTERNALERROR＆gt; IndexError：列表索引超出范围
