Outline
The need for testing Dynamic Applications
The main difficulties of testing OSGi Applications
DA-Testing – a framework for testing Dynamic OSGi-based Applications
Example: Testing “Dynamic Store” application with DA-Testing

Why Testing Dynamic Applications?
To verify application’s dynamicity
Applications should not be considered dynamic unless they have tests which verify their dynamicity
To validate patches and updates prior to installing them in the production environment

OSGi Application Testing Difficulties?
Too much of required maintaining code
Readability of the Testing Code
Reusability of already available Testing Code
Class Casting problems

How DA-Testing solves these problems?
Provides a Dynamic Oriented Tests Structure
More suitable structure for testing Dynamic Applications
Increases Testing Code reusability
Provides an OSGi-friendly API for testers
Increases coding efficiency by reducing testing code size and handling common OSGi testing aspects
Runs all tests in the OSGi Environment
No Class Casting problems

DA-Testing Concepts: Test Scenarios
Reflect Dynamicity Scenarios that we expect the application to have
Examples: Runtime substitution of domain services, installation of patch bundles, etc.
DA-Testing executes Test Scenarios to emulate changes in the OSGi Environment

DA-Testing Concepts: Test Cases
Test Cases are executed as reactions to changes in the OSGi Environment
They contain assertions that validate the behavior of the application

Final Notes
DA-Testing is a Testing Framework which is optimized for testing Dynamic OSGi-based applications
It increases the quality of Dynamic OSGi-based applications by providing common guidelines for testing dynamic applications
It increases the efficiency of the testing process by handling most common problems that testers of OSGi-based applications have
