我正在跨多个文件运行nosetests,并遇到与特定文件导入有关的错误,好吧,我实际上不确定该错误与什么相关,我认为这是随着其修补的进口或某些内容。错误本身看起来像:
(我为使用@Patch Decorator的每个测试功能遇到了其中一个错误)

AttributeError: 'module' object has no attribute 'utils'
包装结构看起来像这样:
my_package
- my_module
- __init__.py
- utils.py
- other.py
- tests
- test_utils.py
- test_other.py
nosetests命令:
nosetests -e unit --with-coverage --cover-package=my_package --cover-erase --cover-xml --with-xunit tests --nocapture
所以很奇怪的是,如果我仅在utils测试类本身上运行nosetests,它运行良好,所有导入工作且所有补丁都可以正常工作,没有错误,所有测试都通过了。
这是test_utils.py文件的样子:
from my_module.utils import *
class TestBusinessProcess(unittest2.TestCase):
@patch('my_module.utils.something')
def test_some_utils_function(self, something_mock):
# test implementation..
# this function will throw:
# AttributeError: 'module' object has no attribute 'utils'
# when running whole tests folder and not on individual test file
pass
@patch('my_module.utils.something_else')
def test_some_other_utils_function(self, something_else_mock):
# test implementation..
# same as above
pass
在其他测试文件中进行测试的一个示例,该测试在运行两种方式时都没有问题:
from my_module.other import *
class TestBusinessProcess(unittest2.TestCase):
@patch('my_module.other.something')
def test_some_function(self, something_mock):
# test implementation..
# no issues!
pass
@patch('my_module.other.something_else')
def test_some_other_function(self, something_else_mock):
# test implementation..
# no issues!
pass
任何帮助都非常感谢。
我仍然不知道有什么问题,但这似乎与导入有关。
无论如何,这个解决方法解决了问题,但不确定为什么。
my_module
中的__init__.py
最初是空的。然后,我对其进行了编辑以揭示utils.py
的各个功能:
__init__.py
from utils import test_some_utils_function, test_some_other_utils_function
__all__ = [
"test_some_utils_function",
"test_some_other_utils_function"
]
