To scrape images in C#, you can use the HTMLAgilityPack library for parsing HTML and retrieving image URLs. Here's a basic example

Install HTMLAgilityPack

You can install the HTMLAgilityPack NuGet package using the following command in the Package Manager Console:

Install-Package HtmlAgilityPack

Write a C# script to scrape images:

using System;
using System.Collections.Generic;
using HtmlAgilityPack;

class Program
{
    static void Main()
    {
        string url = "https://example.com"; // Replace with the URL of the page you want to scrape images from

        // Download HTML content from the URL
        HtmlWeb web = new HtmlWeb();
        HtmlDocument document = web.Load(url);

        // Extract image URLs
        List imageUrls = ExtractImageUrls(document, url);

        // Print the extracted image URLs
        foreach (string imageUrl in imageUrls)
        {
            Console.WriteLine(imageUrl);
        }
    }

    static List ExtractImageUrls(HtmlDocument document, string baseUrl)
    {
        List imageUrls = new List();

        // Select image elements using XPath
        var imageElements = document.DocumentNode.SelectNodes("//img[@src]");

        if (imageElements != null)
        {
            foreach (var imageElement in imageElements)
            {
                // Extract image URL from the src attribute
                string imageUrl = imageElement.GetAttributeValue("src", "");

                // Make the URL absolute if it's a relative URL
                imageUrl = new Uri(new Uri(baseUrl), imageUrl).AbsoluteUri;

                // Add the URL to the list
                imageUrls.Add(imageUrl);
            }
        }

        return imageUrls;
    }
}

This script uses HTMLAgilityPack to load the HTML content of a webpage and extract image URLs using XPath. The ExtractImageUrls method selects image elements with the XPath query "//img[@src]", retrieves the src attribute, and converts relative URLs to absolute URLs.

Run the script:

Replace the url variable with the URL of the webpage you want to scrape images from.

Run the script to see the list of image URLs.

To run GUI autotests in GitLab CI\CD using Docker, Selenium, and PyTest, you can follow these steps:

1. Create a .gitlab-ci.yml file in the root directory of your project. This file will define the pipeline and the jobs for your CI\CD process.

2. Configure the pipeline to use the appropriate image for your tests. In this case, you can use a Python image with the required dependencies installed.

3. Define the before_script section to set up the environment for the tests, including installing the necessary packages and downloading the required drivers for Selenium.

4. Define the test job to run the PyTest tests using the Selenium WebDriver.

Here's an example of a .gitlab-ci.yml file:

stages:
  - test

variables:
  SELENIUM_CHROME_DRIVER: '102.0.5005.62'
  SELENIUM_FIREFOX_DRIVER: '0.26.0'

image: python:3.8

cache:
  paths:
    - .venv
    - requirements.txt

before_script:
  - apt-get update -qq
  - apt-get install -y --no-install-recommends \
      build-essential \
      wget \
      xvfb \
      xvfb-run
  - pip install --upgrade pip
  - pip install --quiet --upgrade pytest
  - pip install --quiet selenium
  - pip install --quiet webdriver-manager
  - wget https://github.com/SeleniumHQ/selenium/releases/download/v${SELENIUM_CHROME_DRIVER}/chromedriver_linux64.zip
  - unzip chromedriver_linux64.zip chromedriver
  - wget https://github.com/SeleniumHQ/selenium/releases/download/v${SELENIUM_FIREFOX_DRIVER}/geckodriver-v${SELENIUM_FIREFOX_DRIVER}
  - mv geckodriver-v${SELENIUM_FIREFOX_DRIVER} geckodriver

test:
  stage: test
  script:
    - pytest tests/
  tags:
    - selenium
  artifacts:
    reports:
      - html
  only:
    - master
    - merge_requests

This .gitlab-ci.yml file defines a single stage called test that runs the PyTest tests in the tests/ directory. The before_script section installs the necessary dependencies, downloads the Selenium WebDriver for Chrome and Firefox, and sets up the environment for running the tests.

The tags: - selenium line ensures that the job runs on a runner with the selenium tag, which should have the appropriate Selenium WebDriver installed. The artifacts: reports: - html line enables the generation of HTML reports for the test results.

The only: - master - merge_requests line specifies that the tests should be run on every commit to the master branch and on every merge request.

Once you've set up the .gitlab-ci.yml file, commit and push it to your repository. Then, create a new merge request or push to the master branch to trigger the CI\CD pipeline and run the GUI autotests using Docker, Selenium, and PyTest.

A proxy server is responsible for acting as an intermediary between a client and a destination server, handling requests and responses on behalf of the client. Its primary functions include:

1. Access control: A proxy server can be configured to control access to certain resources or websites based on user authentication, IP address, or other criteria. This can help organizations enforce access policies and restrict access to inappropriate or unauthorized content.

2. Caching: Proxy servers can cache frequently accessed content, such as web pages, images, and other files, to improve performance and reduce the load on the destination server. This can result in faster response times for clients accessing previously cached content.

3. Anonymity and privacy: By routing requests through a proxy server, a client can maintain anonymity and privacy. The proxy server's IP address appears as the source of the request, rather than the client's IP address, which can help protect the client's identity and location.

4. Content filtering: Proxy servers can be configured to filter and block certain types of content, such as malicious websites, adult content, or specific keywords. This can help organizations maintain a safe and secure browsing environment for their users.

5. Performance optimization: Proxy servers can optimize performance by compressing data, using content delivery networks (CDNs), or implementing load balancing techniques. This can result in faster load times and improved user experience.

6. Protocol translation: In some cases, proxy servers can translate between different communication protocols, allowing clients to access resources using a different protocol than the destination server supports.

7. Security: Proxy servers can provide additional security by encrypting data transmitted between the client and the destination server, protecting sensitive information from being intercepted or tampered with during transmission.

The main task is to monitor traffic on the local network, as all requests will be handled by an organized proxy. Most often it is used to block access to certain resources in offices.

The easiest way is to try to open any site or application that requires an Internet connection. If the data download goes well, then the VPN is working properly. If there is a "No connection" error, then the VPN is not working properly for some reason.
