python - conftest.py导入错误: No module named Foo

Question

我有以下目录结构

/home/ubuntu/test/
 - Foo/
   - Foo.py
   - __init__.py
 - Test/
   - conftest.py
   - __init__.py
   - Foo/
     - test_Foo.py
     - __init__.py

Foo.py 包含

class Foo(object):
  def __init__(self):
    pass

conftest.py 包含:

import pytest

import sys
print sys.path

from Foo.Foo import Foo

@pytest.fixture(scope="session")
def foo():
  return Foo()

test_Foo.py 包含:

class TestFoo():
  def test___init__(self,foo):
    assert True

如果我运行 pytest 。在 Test 文件夹中然后我得到一个错误，它找不到模块 Foo:

Traceback (most recent call last):
  File "/home/ubuntu/pythonVirtualEnv/local/lib/python2.7/site-packages/_pytest/config.py", line 379, in _importconftest
    mod = conftestpath.pyimport()
  File "/home/ubuntu/pythonVirtualEnv/local/lib/python2.7/site-packages/py/_path/local.py", line 662, in pyimport
    __import__(modname)
  File "/home/ubuntu/pythonVirtualEnv/local/lib/python2.7/site-packages/_pytest/assertion/rewrite.py", line 212, in load_module

  File "/home/ubuntu/test/Test/conftest.py", line 6, in <module>
    from Foo.Foo import Foo
ImportError: No module named Foo
ERROR: could not load /home/ubuntu/test/Test/conftest.py

conftest.py中打印出来的sys.path好像包含了/home/ubuntu/test路径所以应该能找到Foo.py吧？

问题是只有当我将 conftest.py 移动到下面的文件夹时它才有效。

我运行 pytest 3.2.2

错误表明 conftest.py 由于 ImportError 而无法加载。尝试像这样将您的导入移动到 foo fixture 中:

import pytest
import sys
print sys.path


@pytest.fixture(scope="session")
def foo():
    from Foo.Foo import Foo
    return Foo()
