14. DevOps for Mobile - Challenges

15. DevOps for Mobile - Challenges
Mobile Apps are the front-end to a complex(enterprise) back-end system
Mobile Apps are rapidly becoming a critical user interface to enterprise systems

16. Mobile Application Architecture: LinkedIn

17. DevOps for Mobile - Challenges
Fragmented Platforms
iOS forked when iPad came out. Android forked multiple times with each vendor, Kindle Fire, Nook…

18. DevOps for Mobile - Challenges
HTML5, PhoneGap/ Cordova still cannot fully replace native Apps in every situation
Mobile Web is not an acceptable solution. Users want an App
Hybrid Apps are the optimal solution for Apps with non-native needs

19. DevOps for Mobile - Challenges
App stores add additional asynchronous deployment step
Continuous Delivery become ‘deliver and wait’

Virtual Services
System dependencies are a key challenge in setting up test environments:
Unavailable/inaccessible: Testing is constrained due to production schedules, security restrictions, contention between teams, or because they are still under development
Costly 3rd party access fees: Developing or testing against Cloud-based or other shared services can result in costly usage fees
Impractical hardware-based virtualization: Systems are either too difficult (mainframes) or remote (third-party services) to replicate via traditional hardware-based virtualization approaches
Test Virtualization enables to create “virtual services”:
Virtual Services simulate the behavior of an entire application or system during testing
Virtual Services can run on commodity hardware, private cloud, public cloud
Each developer, tester can easily have their own test environment
Developer and testers continue to use their testing tools (Manual, Web performance, UI test automation)

56. IBM Rational Test Virtualization Solution
Test Virtualization is an enabler for continuous Integration Testing
Services, applications, systems are introduced into the continuous integration cycle in a prioritized, controlled fashion.
Actual Service/App
Virtual Service/App
Mobile App under Test
We always want to be testing.
Stub interfacing components out that are unavailable at the time and then re-introduce them when they are available.
Continuous integration testing at a “system” level. When new components are introduced the automated test suite scan be run as regression tests. Thereby controlling the risk of extra functionality being deployed into the test environment by having mitigated the risk through earlier testing against stubs. This is an incremental and iterative approach to integration testing.
Incremental Integration Testing 56

57. IBM Rational Test Virtualization Solution for continuous integration and testing
Avoid time spent installing and configuring software just to discover basic build issues
Smoke tests can be integrated as part of the continuous integration process through deployment automation and test virtualization
Smoke test results are made available to the entire team to shorten resolution
