Feature: showing off behave

  Background: user is lead to the login page
    Given user is lead to the login page

  Scenario: login invalid
    When I log in

我的目录结构是：

E:features\tutorial.feature
E:features\__init__.py
E:features\lib\__init__.py
E:features\lib\pages\__init__.py
E:features\lib\pages\login_page.py
E:features\steps\__init__.py
E:features\steps\tutorial.py

文件“steps/tutorial.py”，第 8 行，在 从 ..lib.pages.login_page 导入 LoginPage KeyError：“'name' 不在全局变量中”

Answer 1

你很可能需要将包名放在导入路径中：

from features.lib.pages.login_page import LoginPage

Answer 2

你能确认你没有相关的进口吗？

作为一种缓解措施，您可以尝试在使用 LoginPage 之前导入它。

@when("I log in")
    def step_impl(context):
    """
    :type context: behave.runner.Context
    """
    from ..lib.pages.login_page import LoginPage
    page = LoginPage(context)
    page.login()
