The document discusses Docker and Selenoid, with Docker being a tool to run applications in isolated containers and Selenoid being a tool for running Selenium tests in isolated Docker containers. Selenoid provides benefits over Selenium Grid like better resource usage, easier installation, and support for running each test in a separate container. The document also provides instructions for installing and running Selenoid using Docker or without Docker on different operating systems.

- 3. Docker Enterprise Application Container 3 Obvious advantages: β’ Convenient application encapsulation.. β’ Understandable monitoring. . β’ Work with Linux, MacOs, Windows. Terminology Docker is used to run software packages called containers. Containers are isolated from each other and bundle their own application, tools, libraries and configuration files. Containers are an abstraction at the app layer that packages code and dependencies together. Containers take up less space than VMs (container images are typically tens of MBs in size), can handle more applications and require fewer VMs and Operating systems. An instance of an image is called a container. You have an image, which is a set of layers as you describe. If you start this image, you will have a running container of this image. You can have many running containers of the same image.

Docker Install docker on Mac/Windows 4 Additional info : β’ Advanced (CPUs: 3, Memory: 2048 MB, Swap: 2048 MB) β’ Daemon (Experimental features checkbox unmarked) . β’ *Shared Drives (Drive C should be shared - checkbox marked) Install latest Docker for Windows https://hub.docker.com/editions/community/docker-ce-desktop- windows Install latest Docker for Mac https://hub.docker.com/editions/community/docker-ce-desktop-mac unzip latest Kitematic to ./Docker/Kitematic folder
- 5. Docker Additional commands: 5 β’ kill all running containers with docker kill $(docker ps -q) β’ delete all stopped containers with docker rm $(docker ps -a -q) β’ delete all images with docker rmi $(docker images -q)
- 6. Selenium grid Selenium grid disadvantages 6 Time-consuming deployment process 1.Install Java Development Kit 2.Download Selenium Server JAR latest version 3.Download Web driver required versions 4.Unzip Web driver 5.Install the required versions of browsers 6.Input long commands. Performance speed reduction The hub decelerates if multiple browsers are run in different nodes. Complex launch commands
- 7. Selenoid Selenium server/grid vs Selenoid 7 Features: β’ Isolated environment β’ Resources consumption and utilization β’ Installation β’ Support of multiple browser versions β’ Focus β’ User interface and logs
- 8. Selenoid Isolated environment 8 β’ Selenoid allows running each browser in a separate container, which enables full isolation of the browser environment.
- 9. Selenoid Resources consumption and utilization 9 β’ Since the Selenium Server is written in Java, the resources consumption under heavy load increases significantly. β’ Selenoid enables to maintain a high load without additional waste of resources. β’ On average, during 10 running sessions Selenium Server consumes 500 MB of RAM, while the rate of Selenoid is only 50-60 MB. β’ In addition, all inactive containers are removed at the end of each session. Thus, the level of free memory is always appropriate.
- 10. Selenoid Installation 10 β’ Unlike Selenium Grid deployment process, the one of Selenoid requires little time and effort. It presupposes Docker installation and the input of one command.
- 11. Selenoid Support of multiple browser versions 11 β’ Several containers with the appropriate browsers are to be built.
- 12. Selenoid Focus 12 β’ Challenges may emerge if multiple browsers are run on the same machine within Selenium Grid. β’ Selenoid allows running each test in a separate container. Thus, this problem is eliminated.
- 13. Selenoid User interface and logs 13 β’ Itβs challenging to obtain logs for certain browser sessions in terms of Selenium Grid. On the contrary, all available logs are accessed easily in Selenoid. β’ Selenoid is convenient to use due to the informative interface.
- 14. Selenoid Selenoid advantages 14 Selenoid advanced features: β’ Data storage in RAM β’ Various screen resolution types β’ Browser screen display β’ Video recording of tests
- 15. Selenoid Data storage in RAM 15 β’ Selenoid stores all temporary files in tmpfs. β’ Tmpfs is a temporary file repository that allows storing files in RAM, access to which is performed much faster than to the file system of the hard drive.
- 16. Selenoid Various screen resolution types 16 β’ QA engineers can configure the appropriate screen resolution for a running container on their own by setting the required parameters in the Browser Capabilities.
- 17. Selenoid Browser screen display 17 β’ Selenoid enables engineers to connect to the Virtual Network Computing port during tests execution and access the screen of the desired browser.
- 18. Selenoid Video recording of tests 18 β’ Itβs possible to record the video of the tests performed. β’ For instance, the activation in the Google Chrome browser is implemented by setting the parameter true in the Browser Capabilities:
- 20. Selenoid Configuration manager 20 Important possibilities: β’ change the directory of browser configuration file β’ limit maximum parallel sessions β’ change the video output directory β’ limit memory and CPU usage
- 21. Selenoid Selenoid UI 21 Features list: β’ Stats and sessions β’ Capabilities β’ Logs & VNC
