Selenium vs Puppeteer: Automation Framework Selection

What's the difference between these two automation tools?

Automated testing guys must have struggled to choose Selenium or Puppeteer. let's start with a big conclusion:For compatibility with old projects use Selenium, for new projects prioritize Puppeteer.The newer devices will be Type-C. As a chestnut, it's like choosing a charging cable for your cell phone; old devices are limited to MicroUSB, and newer devices choose Type-C with their eyes closed.

It's interesting to see the difference in how proxy IPs are played in these two tools: Selenium has to configure the proxy with an Options object, while Puppeteer just plugs it into the launch parameter. Take our ipipgo proxy as an example:

 Selenium version
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument('--proxy-server=http://user:pass@gateway.ipipgo.com:9020')
driver = webdriver.Chrome(options=options)

// Puppeteer version
const puppeteer = require('puppeteer');
const browser = await puppeteer.launch({
  args: ['--proxy-server=http://user:pass@gateway.ipipgo.com:9020']
});

Pitfalls in Proxy Configuration Fact Sheet

The most common problem encountered in practice is that theAgent CertificationSelenium relies on third-party libraries to handle pop-ups, and Chrome's -proxy-server parameter is blind when it comes to proxies that require account passwords. This is where ipipgo'sWhitelist Authentication ModeIt comes in handy to bind the server IP for direct password-free use.

Practical anti-blocking guide

Doing data collection is most afraid of IP being blocked. Here's a tawdry operation: use ipipgo'sDynamic Residential AgentsModified in conjunction with browser fingerprinting. For example, Puppeteer can be disguised by userAgent and viewport randomization:

// Fake triple play
await page.setUserAgent(randomUA);
await page.setViewport({width: randomW, height: randomH});
await page.evaluateOnNewDocument(() => {
  delete navigator.webdriver; }); await page.evaluateOnNewDocument(() => {
}); await page.evaluateOnNewDocument(() => { delete navigator.

Frequently Asked Questions

Q: What should I do if I can't connect to the agent?
A: First check whether the whitelist is bound, ipipgo's control panel has real-time connection logs. Then try to access the target website without proxy to rule out network problems.

Q: What if I need to open more than one agent at the same time?
A: Use ipipgo'smultiport packageIf you have a browser instance, you can assign a separate port to each browser instance. Remember to set -proxy-bypass-list to bypass local traffic.

Q: How does mobile automation play with agents?
A: Appium framework can reuse Selenium's proxy configuration, but it is more recommended to use ipipgo's4G Mobile Agent, simulating real base station signals.

From personal experience, it is recommended to find out the business needs first. The need for cross-browser compatibility on the choice of Selenium, the pursuit of execution efficiency with Puppeteer. regardless of which to choose, remember to match the ipipgo proxy, or minutes by the target site to pull the black.
