我正在尝试针对Travis CI上的多个Python变体测试我的应用程序。在Python 2.7中,测试按预期传递。但是,在Python 3.4中我得到了这个追溯
ERROR: tests.test_mymodule (unittest.loader.ModuleImportFailure)

from mymodule import MyModule
ImportError: cannot import name 'MyModule'
在Python 3.5中,我得到了这个(类似,但与3.4完全不同)

我的测试脚本具有以下导入:
import unittest
from mock import patch
from mymodule import MyModule
在特拉维斯,我试图通过两个
运行测试python setup.py test
和
python -m unittest discover
我__init__.py
的{{1}}看起来像这样:
mymodule
from mymodule import MyModule
包含mymodule.py
类。
同样,由于导入错误,这些工作在Python 2.7上,但不在3.4或3.5上。我需要调整我的导入以允许我的测试在Python 2.7和Python 3.4 / 3.5中运行?
答案 0 :(得分:0)
假设你有这样的项目结构:
您确实会收到该错误,因为您应该更明确地了解python3中的导入: Changes in import statement python3
因此,只需将mymodule/__init__.py
中的import语句编辑为显式:
from .mymodule import MyModule
