Kubernetes your tests! automation with docker on google cloud platform
Download as PPTX, PDF5 likes6,127 views
The document discusses the transition from manual post-deployment verification to automated testing using Docker and Kubernetes on Google Cloud Platform (GCP), emphasizing the benefits of fast feedback, stable environments, and resource isolation. It outlines the architecture of Selenium testing using containers, highlighting challenges in mobile testing and the need for improved orchestration and scaling capabilities. Future plans include expanding support for various cluster management systems and enhancing traditional Selenium tools through containerization.

- 4. Short Story From Manual Post Deployment Verification TO Automation
- 5. ❏ Fast feedback ❏ Stable Environment ❏ Isolation ❏ Investigation tools - Hard to support (Video/HAR) ❏ Scale ❏ Efficiency ❏ Browser diversity ❏ Mobile Support Requirements
- 6. Selenium Hub Running Test Static VMs Supported Requirements Browser diversity Mobile Support Parallelism Traditional Selenium Grid
- 7. Ranking: Tooling Deployment/ Configuration Feedback Isolation Efficiency Scalability ❏ Less stable ❏ Crashes - require restarts ❏ Cancel build in progress leave open sessions ❏ Investigation tools - Hard to support (Video/HAR) ❏ Manual grid node Configuration/deployment ❏ Not scalable ❏ Slow feedback ❏ Not efficient - idle grid machines Facing Issues
- 9. Cattlevs.Pets VM Container ● When they get ill you nurse them back to health ● You name them! And take of them! ● When they get ill you get another one! ● They are almost identical to one another ● Don't have specific names. Given numbers ● Can be simply replaced if they die
- 10. What Docker gives us ? ● Build it once run it everywhere! ● Resource Isolation ● Test Isolation ● Package format ● Implementation of a container Docker
- 11. Chrome FirefoxVNC Server Selenium Server Hub/Node JAR Mobile Android What is in a Selenium Container ?
- 12. VM VM VM VM Nodes HUB N Hub’s Running Tests Selenium Grid Architecture Makeover
- 14. DEMO
- 15. We need more than just Packaging and Isolation: ● Orchestration - Distribute containers ● Health Checks ● Resilience and Self-healing ● Scaling - making jobs bigger or smaller Kubernetes Orchestrator

- 17. Testing on the Cloud!
- 18. Benefits of Cloud Platform ● Kubernetes cluster in a click of a button (GCP) ● No idle machines - Use when needed ● Costs per build/test - measurable ● Not part of Liveperson network ● Geolocation simulation
- 19. DEMO

- 24. Ranking: Tooling Deployment/ Configuration Feedback Isolation Efficiency Scalability ❏ Investigation tools - Video tools not reliable and not stable. ❏ Feedback ❏ Improved BUT still needs to wait for nodes to connect into Hub ❏ Point of failures ❏ Hub/Nodes is more failure points in the architecture that not really necessary Facing Issues
- 26. waseemh-mac$ java -jar selenium-server-standalone-2.53.1.jar -role Selenium server can run in one of the following roles: hub as a hub of a Selenium grid node as a node of a Selenium grid standalone as a standalone server not being a part of a grid Test Hub Selenium Server (Node) Selenium Standalone
- 27. Non-Grid Solution ● Fast → Deploy Selenium Standalone containers on-demand ● Short-lived → Selenium containers are destroyed once test ends ● Distribute and manage containers with Kubernetes Test createRemoteWebDriverSession(caps) VM VM VM VM new RemoteWebDriver(External Endpoint)

- 38. Beyond Selenium... Deploy any test dependency inside a container ● Web Servers (/modules/nginx) ● Temporary Databases (/modules/mysql) ● Mock Servers (/modules/wiremock) ● Any Docker Image (/modules/custom)
- 39. Talking Together... Web Application Nginx Ephemeral Selenium Ephemeral EP Test Script EP WireMock Ephemeral EP REST API HTTP
- 40. Ephemerals - Future Plans ● REST API (for non-Java tests) ● Support more cluster management systems: ○ Apache Mesos ○ Docker Swarm ● More modules
- 41. Takeaways ● Enhance traditional Selenium tools ● Containerization - Short lived, throwaway instances ● Scalable tests with Containers Orchestration ● Benefits of Testing on Cloud Platforms
