python - 导入错误 : No module named base

Question

我正在尝试为我的第一个登录测试实现 PageObject 模式。运行它时我收到以下错误:

>> py.test -v test_login.py 
============================= test session starts ==============================
platform linux2 -- Python 2.7.3 -- pytest-2.3.4

==================================== ERRORS ====================================

../pages/__init__.py:1: in <module>
>   from loginPage import LoginPage
../pages/loginPage.py:3: in <module>
>   from base import BasePage
E   ImportError: No module named base

这是python路径:

Pythonpath: PYTHONPATH="${PYTHONPATH}:/usr/lib/python2.7/"

export PYTHONPATH

就我的第一个测试而言，很多代码都是复制粘贴的，也许它有问题，但我无法理解。对于这一点上的任何建议，我们将非常高兴。

下面还有我所谓的 PageObject 实现的结构和内容:

Answer 1

您的base 模块位于ui 模块中。因此行:

from base import BasePage

应该是:

from ui.base import BasePage
