用户在电商网站上浏览商品并将其添加到购物车是常见的操作。我们将编写测试用例来验证这些功能。

**页面对象：商品页面**

Python复制

```python
# pages/inventory_page.py
from selenium.webdriver.common.by import By

class InventoryPage:
    def __init__(self, driver):
        self.driver = driver
        self.add_to_cart_button = (By.ID, "add-to-cart-sauce-labs-backpack")
        self.cart_icon = (By.CLASS_NAME, "shopping_cart_link")

def add_item_to_cart(self):
        self.driver.find_element(*self.add_to_cart_button).click()

def go_to_cart(self):
        self.driver.find_element(*self.cart_icon).click()
```

# tests/test_inventory.py
import pytest
from pages.login_page import LoginPage
from pages.inventory_page import InventoryPage

@pytest.fixture
def browser():
    driver = webdriver.Chrome()
    yield driver
    driver.quit()

def test_add_item_to_cart(browser):
    login_page = LoginPage(browser)
    login_page.open()
    login_page.login("standard_user", "secret_sauce")

inventory_page = InventoryPage(browser)
    inventory_page.add_item_to_cart()
    inventory_page.go_to_cart()
    assert "Your Cart" in browser.title
```
