Using Playwright and Selenium for Web Page Title Verification and Best Practices

This example shows how to use

# 导入 Playwright
from playwright import sync_playwright
def test_hello_world():
    """
    这个测试函数用于验证 "Hello, World!" 页面的标题是否正确显示
    """
    # 创建 Playwright 浏览器实例
    playwright = sync_playwright().start()
    # 打开新页面
    page = playwright.chromium.open('http://example.com')
    # 等待页面加载完成
    page.wait_for_load_state('networkidle')
    # 获取页面标题
    title = page.title()
    # 验证标题是否为 "Hello, World!"
    assert title == "Hello, World!"
    # 关闭浏览器
    playwright.stop()
if __name__ == "__main__":
    # 运行测试
    test_hello_world()

to open a browser, navigate to a page, wait for it to load, retrieve the title with page.title(), and assert that it matches the expected string.

The page.title() method works by querying the browser's document.title property via the DOM; Playwright sends a request to the browser, receives the title value, and returns it to the script, where it can be compared with an expected value using assert.

A comparable Selenium example is provided below:

# coding=utf-8
import time
from selenium import webdriver
driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(6)
driver.get("http://www.baidu.com/")
time.sleep(1)
driver.find_element_by_link_text("新闻").click()
time.sleep(1)
print(driver.title)  # title 方法可以获取当前页面的标题显示的字段
driver.quit()

The article then lists important considerations when using Playwright or Selenium, including selecting the appropriate library, ensuring version compatibility, proper installation and configuration, understanding browser and driver limitations, handling asynchronous operations, reliable element locating, and following best practices such as the Page Object pattern and data‑driven testing.

To guarantee test stability and reliability, it recommends choosing suitable browsers and versions, using a stable test environment, regularly updating libraries and drivers, handling async code correctly, employing robust locator strategies, managing dynamic content with appropriate waits, separating test data, integrating tests into CI pipelines, monitoring and logging, periodic review and refactoring, and performing robustness testing such as boundary and error‑case scenarios.
