Pytest执行用例报Hint: make sure your test modules/packages have valid Python names.

近日，使用Pytest+Appium 实现APP端UI自动化，遇到Pytest收集用例失败的情况。

报错信息如下：

test_room.py:None (test_room.py)
ImportError while importing test module '/Users/XXXX/case/test_room.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
test_room.py:5: in <module>
    from Page.init_page import InitPage
../Page/init_page.py:8: in <module>
    from Page.home_page import HomePage
../Page/home_page.py:4: in <module>
    from Page.room_page import RoomPage
../Page/room_page.py:5: in <module>
    from Page.home_page import HomePage
E   ImportError: cannot import name 'HomePage' from 'Page.home_page' (/Users/XXXX/Page/home_page.py)

目录结构如下：

报错原因分析：

主要是因为home_page.py和room_page.py这两个文件内的类之间有相互调用引起的

• home_page.py涉及代码：

from Page.room_page import RoomPage


class HomePage(BasePage):
    def goto_room(self):
        self.find_element_until_visibility(self._room).click()
        return RoomPage(self.driver)

• room_page.py涉及代码：

from Page.home_page import HomePage


class RoomPage(BasePage):
    def back_home_page(self):
        self.find_element_until_visibility(self._back_btn).click()
        return HomePage(self.driver)

解决办法

直接将room_page.py涉及到的HomePage的引用直接放到特定的函数中引用，而不是整个文件的引用

• 解决后room_page.py涉及代码：

class RoomPage(BasePage):
    def back_home_page(self):
        self.find_element_until_visibility(self._back_btn).click()
        from Page.home_page import HomePage
        return HomePage(self.driver)
