18. Mobile Testing
Scenarios
@dnlkntt

19. • Depending on app use cases this differs from app to app
• The app tech stack also influences the test scenarios for mobile testers and developers

23. Mobile Testing
Challenges
@dnlkntt

24. Mobile Testing Challenges
@dnlkntt

25. Mobile Testing Challenges - Fragmentation
Group 1, Prio A
• High End Devices
• Quad Core CPU
• RAM >4048MB
• Retina, Full HD
Display >= 6“
Group 2, Prio B
• Mid-range devices
• Dual Core CPU
• RAM <=2048MB
• Screen size < 6“
• Software not older
1 year
Group 3, Prio C
• Small devices
• Single Core
• RAM < 1024MB
• Low screen size
and resolution
• Older OS, older
browser
Based on your target group
@dnlkntt

26. Mobile Testing Challenges - Automation
There is no silver bullet
Invest time to find the right test
automation tool that fits your needs
and requirements
Start simple with automation
Invest time in your CI pipeline and
testing infrastructure
Automation should support your
testing activities. It will NEVER
replace testing
Get support from developers
@dnlkntt

27. Release Mobile
Products
Frequently
@dnlkntt

28. Release Mobile Products Frequently
Users expect a bug “free” app
When working with multiple teams,
a release train can help
Planned code freezes and app
releases help to organize & to give
guidance for teams
Every team need to catch the train
in case they want to release
It’s helpful to have a regular release
cycle e.g. every 2 weeks
Freeze the code automatically to
avoid late passengers
