This document discusses test automation using Selenium in a Docker container cluster environment. It begins with an introduction of the speaker and an overview of topics to be covered, including the current technology scenario, Selenium, Selenium Grid, Docker containers, orchestration tools, and recommended third party tools. Key points covered include using Docker containers instead of VMs to run tests in parallel in a lightweight manner, dockerizing tests by building test code into containers, and using orchestration tools like Kubernetes to automate and manage container resources for Selenium Grid. Examples of recommended third party tools that integrate Docker and Selenium are also provided.

▸ Lives in Sydney, enjoys BasketBall and Kayaking

3. WHAT’S IN FOR TODAY?
▸ Today’s Technological scenario
▸ Test Automation using Selenium
▸ Selenium Grid
▸ Docker Containers
▸ Dockerize your functional tests
▸ Orchestration tools for containers
▸ Third party tools

4. TODAY’S TECHNOLOGY SCENARIO
▸ Time to Market
▸ Ship It as soon as possible
▸ Cost Optimization
▸ Compete with less cost
▸ Paradigm shift
▸ Constantly changing environment, CI, CD, DevOps
▸ Distributed computing
▸ Dockers, Cloud computing

5. CONTINUOUS DELIVERY
▸ It’s all about continuous delivery
Continuous Integration >
Continuous Testing >
Continuous Delivery

6. CONTINUOUS-INTEGRATION, TESTING, DEPLOYMENT & DELIVERY
Continuous Delivery != Continually delivering software
Continuous Delivery == Continuous production readiness
Continuous Deployment == Continually delivering software
DevOps is Not a Market, but a Tool-Centric Philosophy That Supports a
Continuous Delivery Value Chain
Thanks to Alister

7. TEST AUTOMATION
▸ Browser Automation library
▸ A suite of tools
▸ JavaScript, Java, Python, C#, Ruby
▸ W3C candidate recommendation

8. SELENIUM-GRID
▸Hub
▸The intermediary and the manager
▸Allocates Test Slots to nodes
▸Takes instructions directly from client, and executes them remotely on nodes
▸Node
▸Registers itself to Hub listed in config
▸Communicates its config to the Hub at registration time:
▸Test Slots per browser
“Hey Hub, I have 1 Slot for Firefox, 5 for Chrome”
▸Receives JSON wire protocol instructions from the Hub
DISTRIBUTED TESTING

10. CHALLENGES
▸ Tests start growing
▸ Parallelization (reduces time)
▸ VM’s are heavy and costly to maintain
▸ Agents are costly
Solution……

11. CONTAINERS TO RESCUE
‣ Light-weight
‣ All pre-requisites apps/libs are packaged.
‣ Also for mobile..
Docker Driven Development
Unified Infrastructure for Dev and Test

12. DOCKER CONTAINERS Vs VM’s
Analogy -
Apartment Villa

13. ▸ Virtual Machine’s
▸ Includes Hardware simulation
▸ Can simulate only few VM’s per server
▸ Slower latency, takes time to load.
▸ Containers
▸ Based on Linux containers
▸ Lightweight - requires only few MB’s
▸ AUFS- Advanced Multi-Layered Unification File System
CONTAINERS VS VM’S

15. DOCKER-SELENIUM
▸ selenium/hub: Image for running a Selenium Grid Hub
▸ selenium/node-chrome: Selenium node with Chrome installed.
▸ selenium/node-firefox: Selenium node with Firefox installed.
▸ selenium/node-phantomjs: Selenium node with PhantomJS installed
▸ selenium/node-chrome-debug: Selenium node with Chrome installed and
runs a VNC server.
▸ selenium/node-firefox-debug: Selenium node with Firefox installed and runs a
VNC server.
All these images needs to be connected to a Selenium Grid Hub

18. DOCKERIZE YOUR TESTS : SHIP YOUR AUTOMATED
TESTS AS A CONTAINER

19. DOCKERIZE YOUR TESTS
NodeJs Java
docker build -t yourImageName .

20. DOCKERIZE YOUR TESTS
docker-compose.yml

21. MOBILES

22. APPIUM-DOCKER-ANDROID
https://github.com/appium/appium-docker-android
‣ Run tests on real device
‣ Connect to your existing Selenium Grid instance
‣ CONNECT_TO_GRID=True
‣ APPIUM_HOST=<ip_address_of_appium_server>
‣ APPIUM_PORT=<port_of_appium_server>
‣ SELENIUM_HOST=<ip_address_of_selenium_hub>
‣ SELENIUM_PORT=<port_of_selenium_hub>

23. DOCKER-ANDROID
https://github.com/butomo1989/docker-android
‣ Run tests in Android emulators
‣ VNC support
‣ Run UI tests for Android applications with different frameworks (appium, espresso, robotium)
‣ Connect to your existing Selenium Grid instance

24. ORCHESTRATION
▸ Automated arrangement, coordination, and management of
containers.
▸ Different tools out there…
DOCKER-SELENIUM IMAGES

25. CAPABILITIES OF ORCHESTRATION TOOLS
Self healing capability
Automatically brings up the containers if for some reasons it goes
down.
and much more….

26. https://github.com/manoj9788/kubernetes-docker-selenium
Self-healing capability - helps restart the node when it goes down automatically,
which helps in test automation.
Scale containers - replicas

27. Package Manager for Kubernetes
Use Helm package
$ helm install stable/selenium
KUBERNETES - SELENIUM

28. RECOMMENDED THIRD PARTY TOOLS BASED ON DOCKER-SELENIUM
Zalenium
https://github.com/zalando/zalenium
▸ Disposable and flexible docker-based Selenium Grid
▸ Live preview of tests running
▸ live dashboards(offline too)
▸ Integration of Cloud Testing solutions
▸ Run on Kubernetes (Beta!)
