Kipp Proxies

To check a proxy for blacklisting, it is necessary to use special tools developed for this purpose. Many proxy-checkers provide free online IP-address verification and provide detailed information related to the proxy servers security. To get it, just enter the IP address of the proxy and click on the "Verify" button.

This is a proxy server integrated into the app to redirect traffic. It allows you to protect yourself from being tracked or to use the program where it is blocked. For example, at one time, users used a proxy server to bypass Telegram blocking.

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();
  }
};

It means organizing a connection through several VPN-servers at once. It is used to protect confidential data as much as possible or to hide one's real IP address. This principle of connection is used, for example, in the TOR-browser. That is, when all traffic is sent immediately through a chain of proxy servers.

There are HTTP proxy, FTP proxy, SOCKS proxy, SMTP proxy, CGI proxy. They differ only in the data transmission protocol used and the purpose for which they are used. For example, SMTP proxy allows you to organize a secure server for e-mail.
