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:
代码语言：javascript复制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:
代码语言：javascript复制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:
代码语言：javascript复制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!
