Wizard Proxy

Chromium does not support proxies in-house. There is a corresponding item in the menu, but clicking on it will open the regular proxy server settings in Windows or MacOS.

Load testing with Selenium involves simulating a large number of concurrent users to assess how a web application performs under different levels of load. While Selenium itself is primarily designed for functional testing and browser automation, you can use additional tools and frameworks in combination with Selenium to perform load testing. Here are some approaches:

1. Using Selenium Grid with Multiple Nodes:

   • Selenium Grid allows you to distribute test execution across multiple machines, called nodes. You can set up a Selenium Grid with multiple nodes, each running different browser instances.
   • Tools like JMeter or Gatling can be used to simulate concurrent user load and distribute the load across the Selenium Grid.
   • The Selenium Grid setup allows you to scale your load tests by adding more nodes.

2. Combining Selenium with JMeter:

   • JMeter is a popular open-source load testing tool. While JMeter is not designed for browser automation, you can use it to simulate user interactions at the HTTP protocol level.
   • Record user scenarios with JMeter's HTTP(S) Test Script Recorder while performing actions in the browser. Convert recorded scenarios to JMeter test plans.
   • Run the JMeter test plans to simulate concurrent users, and monitor the performance of your web application.

3. Using Headless Browsers:

   • Headless browsers (browsers without a graphical user interface) can be used to simulate user interactions without the overhead of rendering pages.
   • Tools like Selenium with headless Chrome or headless Firefox can be used for load testing. Run multiple instances of headless browsers simultaneously to simulate concurrent users.

4. Combining Selenium with Gatling:

   • Gatling is another popular open-source load testing tool that is scriptable in Scala.
   • You can write Gatling scripts to simulate user scenarios using the Selenium DSL (Domain Specific Language) provided by Gatling.
   • Gatling can be used to generate a high load on your web application and measure performance metrics.

5. Using Cloud-Based Load Testing Services:

   • Cloud-based load testing services like BlazeMeter, Flood Element, or BrowserStack can be used for Selenium-based load testing.
   • These services provide scalable infrastructure for running Selenium tests in parallel to simulate a large number of concurrent users.

6. Custom Solutions with WebDriver:

   • You can write custom scripts using Selenium WebDriver to simulate user interactions and run them concurrently using a scripting or programming language (e.g., Python, Java, etc.).
   • Implement logic to run multiple threads or processes, each simulating a user. Be cautious about the limitations and synchronization issues that may arise in a multithreaded environment.

When performing load testing with Selenium, consider the following:

• Monitor the performance of your web application to identify bottlenecks.
• Be mindful of the limitations of the testing environment, especially when running tests on local machines.
• Ensure that your load testing approach aligns with your specific testing goals and requirements.

To enable proxies in your MacBook, you need to go to "System Preferences" (from the "Apple" menu), then open "Network", then - specify the type of connection you are using. Then select "Advanced Settings" (can be named as "Advanced"), then click on "Proxy". And then - either set the parameters manually, or specify a configuration file.

Most often it is used to substitute your real IP address. An example of when this is needed: watching shows on Netflix that are only available to US users. A proxy can be used to make a user logging in from anywhere in the world will be identified by the IP address as a US user. Another option is to test your site through a local web server. A proxy in this case is used to intercept all the traffic in order to analyze it further for errors and failures.

In PlayStation 4 and 5, setting up a proxy server follows a similar algorithm. It is necessary to go to the "Library", select "Settings", open the tab "Network Settings". In the window that appears, click on "Network". Then choose the type of connection you are using. It will be offered to set the DHCP, DNS and then the proxy server parameters step by step. And here you can enable it by manually entering the necessary settings.
