在VS代码中，我尝试使用python，selenium解决问题，行为，但我没有得到正确的输出。你能告诉我问题出在哪里吗？

Question

我的文件夹是

功能/features_files_folder

功能/步骤

在features_files_folder

Omniwyse.feature

法典：

特征：全能

@tagcurrent
Scenario Outline: COMPANY 
Given I load the website "https://www.omniwyse.com"
When I click "About Us" page
Then verify about header element "About Us"

初始化.py

步骤中文件夹

step_def_web_element_handling.py

from behave import given, when, then
from step_impl_web_element_handling import webapp
@given(u'I load the website "{url}"')
def step_impl(context,url):
webapp.load_website(url)
@when(u'I click "About Us" page')
def step_impl_goto_page(context):
webapp.goto_page()

@then(u'verify about header element "{component}"')
def step_impl_verify_component(context, component):
webapp.verify_component_exists(component)

step_impl_web_element_handling.py

from selenium import webdriver
driverpath = "/Users/giris/Downloads/chromedriver"

class WebApp:
def __init__(self):
pass
# self.driver.get("https://omniwyse.com/")
def load_website(self, url):
driver = webdriver.Chrome(executable_path = driverpath)
driver.get(url)
def goto_page(self):
driver = webdriver.Chrome(executable_path = driverpath)
driver.find_element_by_xpath("//a[normalize-space()='About Us']").click()
def verify_component_exists(self, component):
# Simple implementation
driver = webdriver.Chrome(executable_path = driverpath)
assert component in driver.find_element_by_xpath("//h1[contains(text(),'About Us')]"), 
"Component {} not found on page".format(component)

webapp = WebApp()

我的错误step_def_web_element_handling

给定时相同，当

使用 beact 命令运行时的输出

使用默认路径"./features" 尝试基目录： C：\Users\giris\OneDrive\Documents\pythonassignment\omni\features 功能： Omniwyse # features/feature_files_folder/omniwyse.feature：1

1 个功能通过，0 个失败，0 个跳过 0 个方案通过，0 个失败，0 个 跳过 0 步 通过，0 失败，0 跳过，0 未定义 花了 0m0.000s

期望输出：
