【问题描述】:
我正在跨多个文件运行鼻子测试,并收到与导入特定文件有关的错误,我实际上并不确定该错误与什么有关,我认为它要么与导入有关,要么与某些问题有关随着它的修补。错误本身看起来像:
(对于每个使用 @patch 装饰器的测试函数,我都会遇到这些错误之一)

AttributeError: 'module' object has no attribute 'utils'
包结构如下:
my_package
- my_module
- __init__.py
- utils.py
- other.py
- tests
- test_utils.py
- test_other.py
鼻子测试命令:
nosetests -e unit --with-coverage --cover-package=my_package --cover-erase --cover-xml --with-xunit tests --nocapture
所以奇怪的是,如果我只在 utils 测试类本身上运行鼻子测试,它运行良好,所有导入工作和所有补丁工作,没有错误,所有测试通过。
下面是 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
另一个测试文件中的测试示例,无论以哪种方式运行都没有问题:
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
非常感谢任何帮助。
