  • 1. codecentric Nederland BV @pascal_dufour & @hrietman SUCCESFUL TESTING THE CONTINUOUS DELIVERY PROCESS
  • 2. codecentric Nederland BV INTRODUCTION Harald Rietman Developer Scrum Master @hrietman Pascal Dufour Agile Tester @Pascal_Dufour
  • 3. codecentric Nederland BV • Experience with Continuous Delivery? • As a tester, do you need to wait for an acceptable release from developers? • Loose time doing all repetitive manual stuff? • Maintain different environments and software versions manually, over-and-over-and-over… • Is this really release 1.6.5? • All sounds familiar? TYPICAL
  • 4. codecentric Nederland BV Prod BUILDING A RELEASE TEST Local Build Integration server Release build DEV Acc Test Users DEVDEV
  • 5. codecentric Nederland BV WHY CONTINUOUS DELIVERY
  • 6. codecentric Nederland BV GOALS •  Predictability •  Quality •  Speed
  • 7. codecentric Nederland BV CONTINUOUS IMPROVEMENT CYCLE Requires: Discipline & Responsibility
  • 8. codecentric Nederland BV PUSH VS. PULL
  • 9. codecentric Nederland BV APPLICATION STACK Apps / Services / Components Application Configuration Middleware Middleware Configuration Operating System OS Configuration Hardware TESTING
  • 10. codecentric Nederland BV STOP THE LINE!
  • 11. codecentric Nederland BV WHAT IS CONTINUOUS DELIVERY •  Continuous Delivery pipeline •  Automation •  Manual control •  Feedback
  • 12. codecentric Nederland BV WHAT ARE THE MAIN STEPS OF CONTINUOUS DELIVERY? •  Build – compile, unit test, version, package •  Quality – metrics, documentation •  Test – acceptance-, regression- and performance tests •  Provision environments – deployment to test- and staging environment •  Production – green/blue deployment to production
  • 13. codecentric Nederland BV WHAT ARE THE KEY BENEFITS OF CONTINUOUS DELIVERY? •  Low-risk releases •  Faster return on investment in software projects •  Improvement of competitiveness and responsiveness •  Quality improvement of new software versions

  • 15. codecentric Nederland BV MAIN STEPS TO CREATE A CONTINUOUS DELIVERY PIPELINE? •  Getting started with virtual environments, e.g. Amazon EC2 •  Configure your Continuous Integration Server •  Provisioning your Test, Staging and Production environments •  Configure your Continuous Delivery Pipeline •  Create a Dashboard of your Systems
  • 16. codecentric Nederland BV EXAMPLE ! Elke stage een slide.
  • 17. codecentric Nederland BV WHAT ARE THE MAIN STEPS OF CONTINUOUS DELIVERY?
  • 18. codecentric Nederland BV TOOLING THAT CAN HELP YOU
  • 19. codecentric Nederland BV EXAMPLE – TECHNOLOGY STACK •  Amazon EC2 (Virtualization, Cloud) •  Jenkins (CI Server) •  Git/Github (Version Control) •  Sonar (Code Quality) •  jUnit (Unit Tests) •  jBehave (Acceptancetests) •  Selenium (UI Tests) •  Puppet (Provisioning) •  Tomcat (Application Server) •  Artifactory (Artifact Repository) •  Maven (Build Tool) •  jMeter (Performance Tests) •  AppDynamics (Performance Tests) •  Liquibase (DB Versioning)
  • 20. codecentric Nederland BV OUR SETUP https://github.com/... CD Server Test Server User Acceptance Test Server Production Cluster Blue / Green CD Slave

  • 23. codecentric Nederland BV ASK YOURSELF •  Which parts are tested how? •  What remains to be tested?
  • 24. codecentric Nederland BV WHAT DO WE TEST WHERE AND WHEN? •  Automation is key •  Do what we do best •  Team effort
  • 25. codecentric Nederland BV MANUAL TESTING Still required: •  Smoke testing •  Exploratory testing •  User acceptance testing
  • 26. codecentric Nederland BV ANATOMY OF A DEPLOYMENT PIPELINE Release •  Every change results in a trigger of the deployment process •  Software is build once and only once •  The same deployment process for every environment •  Deployment in production-like environments Commit Automated Acceptance Test Automated Capacity Test Manual Testing Fast Feedback Trust in Application Stability Done
  • 27. codecentric Nederland BV EXAMPLE ! Elke stage een slide.
  • 28. codecentric Nederland BV SUMMARY •  Continuous delivery is a way to create a stable release process •  Manual testing is (still) necessary •  Pull vs Push •  Dashboard
