10.4 结账流程测试

结账流程是电商网站的关键环节。我们将编写测试用例来验证用户是否能够成功完成结账。

**页面对象：购物车页面**

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

class CartPage:
    def __init__(self, driver):
        self.driver = driver
        self.checkout_button = (By.ID, "checkout")

def checkout(self):
        self.driver.find_element(*self.checkout_button).click()
```

**页面对象：结账页面**

Python复制

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

class CheckoutPage:
    def __init__(self, driver):
        self.driver = driver
        self.first_name_input = (By.ID, "first-name")
        self.last_name_input = (By.ID, "last-name")
        self.postal_code_input = (By.ID, "postal-code")
        self.continue_button = (By.ID, "continue")
        self.finish_button = (By.ID, "finish")

def fill_checkout_info(self, first_name, last_name, postal_code):
        self.driver.find_element(*self.first_name_input).send_keys(first_name)
        self.driver.find_element(*self.last_name_input).send_keys(last_name)
        self.driver.find_element(*self.postal_code_input).send_keys(postal_code)
        self.driver.find_element(*self.continue_button).click()

def finish_checkout(self):
        self.driver.find_element(*self.finish_button).click()
```

**测试用例：结账流程测试**

Python复制

```python
# tests/test_checkout.py
import pytest
from pages.login_page import LoginPage
from pages.inventory_page import InventoryPage
from pages.cart_page import CartPage
from pages.checkout_page import CheckoutPage

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

def test_checkout(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()

cart_page = CartPage(browser)
    cart_page.checkout()

checkout_page = CheckoutPage(browser)
    checkout_page.fill_checkout_info("John", "Doe", "12345")
    checkout_page.finish_checkout()

assert "Thank you for your order!" in browser.page_source
```
