Behave ImportError: No module named features.steps.pages.home_page

Question

我在 Python Behave 中有一个示例 BDD 场景。当我 运行 该功能时，我收到错误消息：

ImportError: No module named features.steps.pages.home_page

我不确定它为什么抱怨。 home_page.py 在 pages 文件夹中，pages 在 steps 文件夹中，steps 文件夹在 features 文件夹中。 在页面文件夹中，我有一个 init.py 文件。
为什么它抱怨找不到 home_page.py?

我的代码是：features\steps.py

from behave import *
#from features.steps.pages import home_page
from features.steps.pages.home_page import HomePage
#from features.steps.pages import search_page
from features.steps.pages.search_page import SearchPage
from features.steps.pages import home_page

@Given ('we are on the homepage')
def step(context):
   context.browser.get('http://www.test.com')

@When ('we enter "{product}" in the search field')
def step(context, product):
   #search_field = context.browser.find_element(By.XPATH, 'id("twotabsearchtextbox")')
   #search_field.send_keys(product)
   home_page = HomePage(context)
   home_page.enter_product_in_search_field(product, context)

@When ('And we click the search button')
def step(context):
   #search_button = context.browser.find_element(By.XPATH, './/*[@id="nav-search"]/form/div[2]/div/input')
   searchPage_results = home_page.click_search_button(context)
   #search_button.click()

@Then ('the list of products are displayed')
def step(context):
   context.searchPage_results.search_products_results(context)
   #wait = WebDriverWait(context.browser, 60)
   #divs =  wait.until(EC.presence_of_all_elements_located((By.XPATH, '//div/a/h2')))
   #for i in divs:
         #div2 = divs + '/a/h2'
         #print divs.get_attribute('value')
         #print divs
         #print i.text
         #print "i"
   #      divs

features\steps\pages\home_page.py

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from search_page import SearchPage

class HomePage(object):

    def __init__(self, context):
        context = context

    def enter_product_in_search_field(self, product, context):
        search_field = context.browser.find_element(By.XPATH, 'id("twotabsearchtextbox")')
        search_field.send_keys(product)
        return self

    def click_search_button(self, context):
        search_button = context.find_element(By.XPATH, './/*[@id="nav-search"]/form/div[2]/div/input').click()
        return SearchPage(context)

features\test_feature.特征

Feature: testing product

Scenario Outline: visit test and search for product
    Given we are on the test homepage
    When we enter "<product>" in the search field
    And we click the search button
    Then the list of products are displayed

    Examples: By product
        | Forumla One |
        | PS4 |
        | Headphones |

我的目录结构是：

E:features\test_feature.feature
E:features\init.py
E:features\pages\init.py
E:features\pages\home_page.py
E:features\pages\search_page.py

完整的错误是：

    E:\RL Fusion\projects\BDD\Python BDD\PythonBDD\Selenium Sample\features>behave test_feature.feature

    from features.steps.pages.home_page import HomePage
ImportError: No module named features.steps.pages.home_page

我该如何解决这个问题？

谢谢，里亚兹

您似乎没有正确导入模块。要将目录转换为模块，请将所有 init.py 文件更改为 __init__.py。

然后当您在 features/steps.py 中导入时，您可以使用：

from pages.home_page import HomePage
