Panther is a convenient standalone library to scrape websites and to run end-to-end tests using real browsers.
Panther is super powerful. It leverages the W3C's WebDriver protocol to drive native web browsers such as Google Chrome and Firefox.
Panther is very easy to use, because it implements Symfony's popular BrowserKit and DomCrawler APIs, and contains all the features you need to test your apps. It will sound familiar if you have ever created a functional test for a Symfony app: as the API is exactly the same! Keep in mind that Panther can be used in every PHP project, as it is a standalone library.
Panther automatically finds your local installation of Chrome or Firefox and launches them, so you don't need to install anything else on your computer, a Selenium server is not needed!
In test mode, Panther automatically starts your application using the PHP built-in web-server. You can focus on writing your tests or web-scraping scenario and Panther will take care of everything else.
Features:
- executes the JavaScript code contained in webpages
- supports everything that Chrome (or Firefox) implements
- allows taking screenshots
- can wait for asynchronously loaded elements to show up
- lets you run your own JS code or XPath queries in the context of the loaded page
- supports custom Selenium server installations
- supports remote browser testing services including SauceLabs and BrowserStack
Requestium is a Python library that merges the power of Requests, Selenium, and Parsel into a single integrated tool for automatizing web actions.
The library was created for writing web automation scripts that are written using mostly Requests but that are able to seamlessly switch to Selenium for the JavaScript heavy parts of the website, while maintaining the session.
Requestium adds independent improvements to both Requests and Selenium, and every new feature is lazily evaluated, so its useful even if writing scripts that use only Requests or Selenium.
Example Use
<?php
use Symfony\Component\Panther\Client;
require __DIR__.'/vendor/autoload.php'; // Composer's autoloader
$client = Client::createChromeClient();
// Or, if you care about the open web and prefer to use Firefox
$client = Client::createFirefoxClient();
$client->request('GET', 'https://api-platform.com'); // Yes, this website is 100% written in JavaScript
$client->clickLink('Get started');
// Wait for an element to be present in the DOM (even if hidden)
$crawler = $client->waitFor('#installing-the-framework');
// Alternatively, wait for an element to be visible
$crawler = $client->waitForVisibility('#installing-the-framework');
echo $crawler->filter('#installing-the-framework')->text();
$client->takeScreenshot('screen.png'); // Yeah, screenshot!
from requestium import Session, Keys
session = Session(webdriver_path='./chromedriver',
browser='chrome-headless',
default_timeout=15)
# then session object can be used like requests and parsel:
title = session.get('http://samplesite.com').xpath('//title/text()').extract_first(default='Default Title')
# other advance functions like POST requests and proxy settings are also available:
s.post('http://www.samplesite.com/sample', data={'field1': 'data1'})
s.proxies.update({'http': 'http://10.11.4.254:3128', 'https': 'https://10.11.4.252:3128'})
# session can also be used like selenium as it exposes all selenium functions.
# like typing keys:
s.driver.find_element_by_xpath("//input[@class='user_name']").send_keys('James Bond', Keys.ENTER)
