我有一个示例 BDD Python 行为代码。当我运行行为 test.feature 时，主页会打开，但随后出现以下错误：
'Context' object has no attribute 'find_element'
完整的错误是：
Scenario Outline: visit test and search for product -- @1.1 By product # test.feature:27
Given we are on the test homepage # steps\steps.py:37
When we enter "<product>" in the search field # steps\steps.py:43
Traceback (most recent call last):
File "C:\Python27\lib\site-packageehave\model.py", line 1456, in run
match.run(runner.context)
File "C:\Python27\lib\site-packageehave\model.py", line 1903, in run
self.func(context, *args, **kwargs)
File "steps\steps.py", line 50, in step

unner.py", line 214, in __getattr__eehave
raise AttributeError(msg)
AttributeError: 'Context' object has no attribute 'find_element'
我的代码片段是：
测试功能：
Feature: testing test
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 |
步骤.py
from behave import given, when, then
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
@given ('we are on the test homepage')
def step(context):
context.browser.visit()
@when ('we enter "{product}" in the search field')
def step(context, product):
search_field = context.find_element(By.XPATH, 'id("twotabsearchtextbox")')
search_field.send_keys(product)
@when ('we click the search button')
def step(context):
pass
@then ('the list of products are displayed')
def step(context):
pass
浏览器.py
from selenium import webdriver
class Browser(object):
base_url = 'http://www.test.com'
driver = webdriver.Chrome("E:\Selenium Server\chromedriver.exe")
driver.implicitly_wait(10)
def close(self):
"""
close the webdriver instance
"""
self.driver.quit()
def visit(self, location=''):
"""
navigate webdriver to different pages
"""
url = self.base_url + location
self.driver.get(url)
def find_by_id(self, selector):
"""
find a page element in the DOM
"""
return self.driver.find_element_by_id(selector)
环境.py
from browser import Browser
from selenium import webdriver
def before_all(context):
context.browser = Browser()
def after_all(context):
context.browser.close()
它没有找到 find_element，我想使用它以便可以在网页上找到元素。在 Behave 中使用 Fine_element 的正确语法是什么？
谢谢，里亚兹
