Installing Selenoid on MXLinux Latest

Introduction

Selenoid is a powerful and lightweight tool for running Selenium tests in Docker containers. It provides an easy way to run multiple browsers, with different versions and configurations, on a single machine or cluster.

In this tutorial, we will walk you through the steps to install Selenoid on MXLinux Latest.

Prerequisites

• An MXLinux Latest instance
• Docker installed on your system
• Basic knowledge of the command line interface (CLI)

Step 1: Download the Selenoid Configuration Files

To install Selenoid, you need to download the configuration files from the Selenoid repository. Open a terminal window and run the following command:

$ curl -s https://aerokube.com/cm/bash | bash \
&& ./cm selenoid start \
--vnc \
--tmpfs 128 \
--args "-limit 20 -service-startup-timeout 60s"

This command will download the Selenoid configuration files and start the Selenoid server with the following options:

• --vnc: enables VNC support for the browsers, which allows you to see the tests running in real-time.
• --tmpfs 128: allocates 128MB of RAM to the temporary file system, which improves performance.
• --args "-limit 20 -service-startup-timeout 60s": sets the maximum number of browsers that can run simultaneously to 20 and the service startup timeout to 60 seconds.

After the files are downloaded, you will see a message indicating that the Selenoid server has started:

Selenoid has been started

Step 2: Verify the Installation

To verify that Selenoid is running correctly, open the following URL in your browser:

http://localhost:4444/status

You should see a JSON response containing information about the Selenoid server:

{
  "total": 0,
  "used": 0,
  "queued": 0,
  "pending": 0,
  "browsers": {}
}

This indicates that the server is running correctly and there are currently no tests running.

Step 3: Run a Test

To run a test using Selenoid, you need to create a script that uses the Selenium WebDriver API to interact with a browser. Here's an example script that opens the Google homepage and searches for the keyword "Selenoid":

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Remote(
    command_executor="http://localhost:4444/wd/hub",
    desired_capabilities={
        "browserName": "chrome",
        "browserVersion": "latest",
        "selenoid:options": {
            "enableVNC": True,
            "enableVideo": False
        }
    }
)

driver.get("http://www.google.com")

input_el = driver.find_element_by_name("q")
input_el.send_keys("Selenoid")
input_el.send_keys(Keys.RETURN)

driver.quit()

Save this script to a file named test.py and then run the following command to execute the test:

$ python test.py

You should see a Chrome browser window open and navigate to the Google homepage. After a few seconds, the search results for "Selenoid" will appear.

Conclusion

Congratulations! You have successfully installed Selenoid on MXLinux Latest and run a Selenium test using the Selenoid server. This powerful tool makes it easy to run tests on multiple browsers with different configurations and versions, all on a single machine or cluster. Happy testing!
