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 get the content of an HTML element (such as text inside a tag) using Selenium, you can use the text property of the WebElement. Here's an example in Python:

from selenium import webdriver

# Create a WebDriver instance (e.g., Chrome)
driver = webdriver.Chrome()

# Navigate to a webpage
driver.get("https://example.com")

# Find an element by its CSS selector (replace with your actual selector)
element = driver.find_element_by_css_selector("h1")

# Get the text content of the element
element_text = element.text

print("Element Text:", element_text)

# Close the browser when done
driver.quit()

In this example:

1. A WebDriver instance is created (using Chrome in this case).
2. The browser navigates to a webpage (replace the URL with your desired URL).
3. An HTML element is located using find_element_by_css_selector. You can use other locators such as ID, class name, XPath, etc., based on your needs.
4. The text property of the WebElement is used to retrieve the text content of the element.
5. The text content is printed to the console.

Adjust the CSS selector in the find_element_by_css_selector method to match the HTML element you want to extract content from.

Remember that the text property returns the visible text of the element, excluding any hidden text or text inside child elements. If you need to capture all text content, including hidden elements, you may need to use other methods to extract HTML content and then parse it accordingly.

To view the proxy settings on your computer, you can follow these steps depending on the operating system you are using:

For Windows:
- Press the Windows key + R to open the Run dialog box.
- Type "inetcpl.cpl" (without quotes) in the Run dialog box and press Enter.
- In the Internet Properties window, go to the Connections tab.
- Click on the "LAN settings" button.
- In the LAN Settings window, you will see the proxy server settings. If there is a checkmark in the "Use a proxy server for your LAN" box, it means you are using a proxy server.

For macOS:
- Click on the Apple menu in the top-left corner of your screen.
- Select "System Preferences" from the dropdown menu.
- Click on "Network" in the System Preferences window.
- Select the network connection you are using (e.g., Wi-Fi, Ethernet) from the left pane.
- Click on the "Advanced" button.
- In the Advanced window, go to the "Proxies" tab to view the proxy settings.

If you're encountering errors while running Selenium WebDriver in Codeception with Yii2:

- Check WebDriver and browser compatibility.
- Verify browser and WebDriver configuration in codeception.yml.
- Ensure Yii2 application is running and accessible at the specified URL.
- Add waits to handle asynchronous behavior.
- Use debugging tools and logging to identify the issue.
- Check user permissions, headless mode, and proxy settings.
- Temporarily disable firewall or antivirus.
- Update Codeception, Yii2, and related dependencies.
- Inspect specific error messages or logs for more information.

Proxy "tunneling" should be understood as the isolation of traffic from the user. It allows you to form a fully protected channel for data exchange, which will be isolated from all other traffic.
