Different options to Selenium WebDriver

My current web scraping process using the Selenium Webdriver for C# and Python is extremely slow, taking about 1.5 days to scrape 35000 data tables. I utilize the Selenium Webdriver to execute Javascript in order to retrieve Java elements from websites. Is there a library or alternative tool that can expedite this process without the need for a Webdriver to execute Javascript and click on webpage elements? I am looking for a faster solution than Selenium for my web scraping needs.

If you're looking for a reliable tool for web functional testing (e2e testing), I highly recommend using TestCafe.

https://i.sstatic.net/lKl9u.gif

TestCafe is an open-source framework that doesn't rely on WebDriver and is based on Node.js, making it fast and efficient.

With TestCafe, tests are executed on the server side and offer a flexible system of Selectors to obtain DOM elements. The ClientFunction feature allows executing JavaScript on the tested webpage, enhancing the test coverage.

Despite its speed, TestCafe maintains stability with its built-in smart wait system, ensuring reliable test results.

Installing TestCafe is straightforward:

1) Make sure you have Node.js installed on your computer (or install it).

2) To install TestCafe, simply run this command in cmd:

npm install -g testcafe

Writing tests with TestCafe is user-friendly. Here's a quick example to get started:

import { Selector } from 'testcafe';

fixture `Getting Started`
    .page `http://devexpress.github.io/testcafe/example`;

test('My first test', async t => {
    await t
        .typeText('#developer-name', 'John Smith')
        .click('#submit-button')
        .expect(Selector('#article-header').innerText).eql('Thank you, John Smith!');
});

3) Run the tests in your chosen browser (e.g. chrome) by running this command in cmd:

testcafe chrome test.js

Review the descriptive results in the console output.

TestCafe supports testing across various browsers: local, remote, cloud, or headless, making it adaptable for different testing environments including Continuous Integration setups.

For efficient browser automation without the need for a graphical interface, I recommend using Selenium with PhantomJSDriver (Ghostdriver). This allows you to easily navigate websites, select elements, submit forms, and perform scraping tasks. Plus, it supports Javascript.

You can access the Selenium documentation here. To use PhantomJSDriver, you will need to download the phantomjs.exe file.

A helpful tutorial for PhantomJSDriver can be found here

Here is the configuration for PhantomJSDriver (as mentioned in the tutorial):

DesiredCapabilities caps = new DesiredCapabilities();
caps.setJavascriptEnabled(true);
caps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, "C://phantomjs.exe");
caps.setCapability("takesScreenshot", true);
WebDriver driver = new PhantomJSDriver(caps);

Alternatively, you can opt for PhantomJS, which is a headless WebKit with a JavaScript API supporting web standards like DOM handling, CSS selectors, JSON, Canvas, and SVG.

This tool is GUI-less and can capture screenshots as well.

Check out an example usage of PhantomJS here:

var page = require('webpage').create();
page.open('http://example.com', function(status) {
  console.log("Status: " + status);
  if(status === "success") {
    page.render('example.png');
  }
  phantom.exit();
});

PS: While JSoup is great for web scraping, it lacks support for JavaScript. For Python users, consider Ghost.py in combination with PhantomJSDriver.

By utilizing the HTMLUnit webdriver, you eliminate the need for a browser which results in faster code execution. To further enhance speed, consider bypassing frameworks and tools entirely by directly querying pages and parsing them for specific information. Keep in mind, though, that this approach may lead to challenges with maintenance and updates.
