Run all UI tests in the container
Make it scalable for parallel execution
Keep the possibility to "watch" the test
Should be triggered by the CI server
Use our internal private cloud infrastructure

We need a containerized UI!We need a containerized UI!

WhyWhy
Support different web testing providers:
Sahi OS
Selenium
... more should follow
Combines DOM access and native screen recognition
OpenSource
no vendor lock in and easy to extend
Ready-to-use Docker images
Cloud-ready: Kubernetes & OpenShift

Monitoring IntegrationMonitoring Integration

CI Pipeline with JenkinsCI Pipeline with Jenkins

Test Management UITest Management UI
Comfortable writing and management of test suites
Direct test execution with integrated live view and logs
Extended reports for easy error detection
Video

What's next?What's next?
Implement Junit 5 test runner
Web UI to handle Sakuli test suites
JavaScript
