... More Challenges

§  Mobile means your users are not in a protected environment

§  Network (Wifi, 3G, GPRS ...) §  Sensors, Bluetooth ...

Learnings

§  Your users are not very patient

§  Quality has direct impact on apps‘ success

§  Challenges: Fragmentation and mobile

use of apps

§  Implication: Mobile QA is a central part of development

There must be an easy solution to handle this ?!

...nope!

What Do I Have to Test?

§  What to test: §  Usability §  Functionality §  Performance §  Edge Cases

§  Approx. 50 use cases (per platform) §  Approx. minimum 20 target devices

Testing Framework

Development QA Production

Unit Tests

Functional Tests

Usability

Sanity

Monitoring

Automation

Manual Edge Cases

Checkups

Manual Approaches

§  Checkups, Usability, Edge Cases, Performance §  Pros: You can test the actual user behavior

§  Cons: Time consuming, inefficient

Continuous Delivery = Continuous Testing

UI Automation Approaches

§  Regression, End-to-end, Integration §  Pro: High test coverage, scalable, time-to-market,

releases resources for manual testing

§  Con: Initial investment, requires technical know-how, maintaining of scripts, no edge cases
