Playwright系列：第3章用Python、Nodejs、Java创建我们第一个脚本

我们基于Playwright实现以下步骤的自动化测试，用Python、Java和Nodejs实现，大家可以对比其中的异同。

1. 启动Chromium浏览器
2. 访问example.com网站 
3. 获取网页标题并打印
4. 点击"More information..."链接
5. 在搜索框输入"Playwright" 
6. 等待2秒   
7. 获取当前页面URL并打印
8. 关闭浏览器

Python示例:

from playwright.sync_api import sync_playwright


def run(playwright):
    chromium = playwright.chromium
    browser = chromium.launch() # 启动Chromium浏览器
    page = browser.new_page() # 新建页面


# 访问示例网站
    page.goto("https://www.example.com/")  


# 获取页面标题
    title = page.title()
    print(title)


# 点击页面元素
    page.click("text=More information...")


# 输入文本
    page.fill("#search", "Playwright")


# 等待2秒
    page.wait_for_timeout(2000)  


# 获取当前URL
    url = page.url() 
    print(url)


# 关闭浏览器
    browser.close()


with sync_playwright() as playwright:
    run(playwright)

Node.js示例:

const { chromium } = require('playwright');


(async () => {
const browser = await chromium.launch();
const page = await browser.newPage();


await page.goto('https://www.example.com/');
const title = await page.title();
console.log(title);


await page.click('text=More information...'); 
await page.fill('#search', 'Playwright');
await page.waitforTimeout(2000);


const url = await page.url();
console.log(url);


await browser.close();
})();

Java示例:

import com.microsoft.playwright.*;


public class Example {
public static void main(String[] args) {
try (Playwright playwright = Playwright.create()) {
      BrowserType chromium = playwright.chromium();
      Browser browser = chromium.launch();
      Page page = browser.newPage();


      page.navigate("https://www.example.com/");
      String title = page.title();
      System.out.println(title);


      page.click("text=More information...");
      page.fill("#search", "Playwright");
      page.waitforTimeout(2000);


      String url = page.url();
      System.out.println(url);


      browser.close();
    }
  }
}

以上三个示例分别使用Python、Node.js和Java实现相同的测试逻辑。我们已经成功创建了第一个Playwright测试脚本,并实现了识别页面元素和简单操作。

接下来我们将继续学习Playwright更强大的页面操作功能,以编写出更丰富的测试脚本!
