- 5. Agenda • Requirements for test environments • Runtime environments • Automation • Sharing of environments • Conclusion
- 6. Types of Tests Functional tests of Utilities Application tests Stress tests Performance tests
- 7. Generic requirements Repeatable Same for all developers Easy deploy and rollback High degree of automatisim Dependency handling Versioned
- 8. Requirements for local environments Small footprint in terms of resources Mainly similar to production Completly local DB Application Server Webserver ... Endian OS Versions Libraries Storage CPU RAM Performan ce
- 10. Runtime environments • Native • Fully virtualized operating system • Container • Sandbox
- 11. Native • Directly on the OS • Complex for some tools (Oracle DB) • Bad portability • Less comparable • No overhead from environment Host OS AppDB
- 12. Fully virtualized operating system • High overhead from environment • Maximum flexibel • Easy to share • Complex handling of dependencies • Network and Startup • Virtual box • Workstation pro (fromer vmware workstation) • HyperV • Kvm • Wsl2 • Parallels Desktop Host OS AppDB Virtualisation OSOS
- 13. Virtual Box
- 14. Container • Less overhead from environment • Shared kernel, but seperate libaries and runtime environment • Flexibel • OS dependencies • Docker • Podman • Libvirt Host OS ContainerContainer AppDB Container Runtime
- 15. Docker • Large distribution • Large amout of prebuild images available on hub.docker.com • Build described as code (Dockerfile)
- 16. Sandbox • Less overhead from environment • Shared kernel and libraries but separated runtime environment • Wine / CrossOver • Windows Subsystem for Linux (Wsl) Host OS Runtime envRuntime env AppDB
- 17. Windows Subsystem for Linux
- 18. Dependencies • Maybe different for developer (linux, windows, macOS) • Maybe different ways of working (IDEs) • Maybe diffrent requirements for frontend, backend, mobile, … • Available integration for IDEs • Breakpoints • Watching variables • Tool dependencies • Docker and Virtual box not in parallel
- 19. Automation
- 20. Automation • Automatic setup and update of the environment • Including Network • Automatic start and stop with dependencies • Automatic local deployment • Same for all developers
- 21. vagrant init vagrant up vagrant ssh Vagrant • Easy setup • Large community and ready to use images + vagrantfiles on app.vagrantup.com • Syntax based on Ruby • Virtual Box, Docker, libvirt, …
- 22. Docker compose • Only for Docker images • YAML files for the config • Supports data persistence, but must be configured
- 23. Kubernetes • Container orchestration • Only for docker or RKT images • Integrated in docker desktop • YAML / JSON files for the config • Supports data persistance, but must be configured
- 24. Handmade Scripts • Very flexible • Huge amount of effort • Hard to fit several environments / OS / … • Seperated tests
- 26. Sharing of environments • Fully virtualized operating system • Remove all controlers (audio/usb) • Remove all images (cd /disktette) • Use VMDK format (short for Virtual Machine Disk) supported by Virtual Box, Vmware , Parallels Desktop, … • Split disks into 2g files • Virtual box • Install latest vbaddins • Use the same version of virtual box
- 27. Sharing of environments • Cointainer • Share definition file (Dockerfile) and image • Small images (minimise additional libraries) • Easy rebuild with docker file
- 28. Conclusion
- 29. Conclusion • A Large bunch of tools and options • Combinations are possible and often useful • Do it yourself is often to much work • Prebuild images are the key to fast testing and current versions • Be careful with network access to your local OS
- 30. What I use ... • Windows Subsystem for Linux (WSL) • Virtual box • Docker inside virtual box • Sometimes an additional DNS server • Vagrant, only for basic vm setup
- 31. Any Questions?
