Selenium is a powerful tool for automating web browsers, and it has various tools and bindings for different programming languages. If you are specifically interested in Selenium tools for JavaScript, you'll likely be working with the Selenium WebDriver bindings for JavaScript. Here are the key components and tools related to using Selenium with JavaScript

WebDriverJS (Selenium WebDriver for JavaScript)

WebDriverJS, also known as selenium-webdriver for JavaScript, is the official Selenium WebDriver binding for JavaScript. It allows you to write automated tests in JavaScript to control web browsers.

You can install WebDriverJS using npm:

npm install selenium-webdriver

Example code snippet using WebDriverJS

const { Builder, By, Key, until } = require('selenium-webdriver');

(async function example() {
  let driver = await new Builder().forBrowser('chrome').build();
  try {
    await driver.get('https://www.example.com');
    await driver.findElement(By.name('q')).sendKeys('webdriver', Key.RETURN);
    await driver.wait(until.titleIs('webdriver - Google Search'), 1000);
  } finally {
    await driver.quit();
  }
})();

Protractor

Protractor is an end-to-end testing framework specifically designed for Angular applications. It uses WebDriverJS internally and extends it to provide additional features for Angular applications.

Protractor can be installed using npm:

npm install -g protractor

Example Protractor configuration file:

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['example-spec.js']
};

WebdriverIO

WebdriverIO is another popular JavaScript framework for end-to-end testing. It is built on top of WebDriverJS and provides a simplified interface for interacting with browsers.

WebdriverIO can be installed using npm:

npm install webdriverio

Example WebdriverIO test script

const { remote } = require('webdriverio');

(async () => {
    const browser = await remote({
        capabilities: {
            browserName: 'chrome'
        }
    });

    await browser.url('https://www.example.com');
    const title = await browser.getTitle();
    console.log('Title:', title);

    await browser.deleteSession();
})();

Nightwatch.js

Nightwatch.js is a testing framework built on top of WebDriverJS that simplifies the process of writing and executing end-to-end tests.

Nightwatch.js can be installed using npm:

npm install nightwatch

Example Nightwatch.js configuration file

module.exports = {
  'Demo Test': function (browser) {
    browser
      .url('https://www.example.com')
      .waitForElementVisible('body')
      .assert.title('Example Domain')
      .end();
  }
};

To optimize the performance of Selenium with Chrome and Chromedriver, you can consider several strategies:

Latest Versions:
Ensure that you are using the latest version of Chrome and Chromedriver. They are frequently updated to include performance improvements and bug fixes.

Chromedriver Version Compatibility:
Make sure that the version of Chromedriver you are using is compatible with the version of Chrome installed on your machine. Mismatched versions may lead to unexpected behavior.

Headless Mode:
If you don't need to see the browser window during automation, consider running Chrome in headless mode. Headless mode can significantly improve the speed of browser automation.

chrome_options.add_argument('--headless')

Chrome Options:
Experiment with different Chrome options to see how they affect performance. For example, you can set options related to GPU usage, image loading, and more.

chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--blink-settings=imagesEnabled=false')

Page Loading Strategy:
Adjust the page loading strategy. For example, you can set pageLoadStrategy to 'eager' or 'none' if it fits your use case.

chrome_options.add_argument('--pageLoadStrategy=eager')

Timeouts:
Adjust timeouts appropriately. For example, setting script timeouts or implicit waits can help to avoid unnecessary waiting times.

driver.set_script_timeout(10)
driver.implicitly_wait(5)

Parallel Execution:
Consider parallel execution of tests. Running tests in parallel can significantly reduce overall execution time.

Browser Window Size:
Set a specific window size to avoid unnecessary rendering.

chrome_options.add_argument('window-size=1920x1080')

Disable Extensions:
Disable unnecessary Chrome extensions during testing.

chrome_options.add_argument('--disable-extensions')

Logging:
Enable logging to identify any issues or bottlenecks.

service_args = ['--verbose', '--log-path=/path/to/chromedriver.log']
service = ChromeService(executable_path='/path/to/chromedriver', service_args=service_args)

You need to open the settings menu, go to "Data and disk", and then - "Proxy settings". There you can enter the address, port number of the intermediate server, as well as username and password for authorization (if necessary).

There are several options for its use: bypassing the blocking of websites, shopping in foreign online stores at regional (local) prices, access to a full library of media content, hiding your real IP-address.

If your ISP blocks you from downloading torrents, turning on your proxy server is the easiest way around the blockage. How exactly this is done depends on the torrent client you are using. For example, in Qbittorrent you need to go to settings, open "Network" tab, check "Proxy-server" and manually specify its settings. The same way uTorrent is configured.
