1. Software IMprovement using Product LinEs Project Presentation (III) - Implementation Liana Lisboa – PM Project: Starship

2. 2 Summary Components OSGi Tests Metrics Strong and Weak Points

3. 3 Components New definition of components  Audio  Actions  Entity  Event  Graphic  Movement  Screen  New component -> Strategies

4. 4 Components (cont.) Actual stage:  Audio  Events  Graphic  Movement  Strategies  Level Demonstration!

5. 5 OSGi 2 Components with OSGi  Audio -> the factory pattern was ignored  Movement A sample example of these components in an application

6. 6 Tests Issues:  Implementation is not totally finished (de-coupling);  It is not hard to validate a component contract if you have: Proper component specification; A process to validate then; Tools to support the activity.  But, it is hard to create automated tests for components that have basically user interaction (i.e. audio, image quality...)  Ideally, the component must come with a test bed for anyone who wants to see if that component fulfills its own acceptance criteria.

7. 7 Tests Practice (applied to Movement component): JUnit to validate contract using mock objects; JUnitPerf for performance measuring; Weak Points (tests)  Integration Tests Strong Points (tests)  It is possible to test components
