The DSML - Description

A Modeling Language to design test scenarios

Resembling UML Sequence diagrams Lifelines: Tester or MobilesMessages:

Tester Mobile: press a key, press the pointer…Mobile Mobile: call, send SMS…

No programming skills are required

A scenario can be adapted for another application

DSM‘10 21

The DSML - Variability Management

In practice: Create a variability point Assign one ore more action to this variability point

A scenario can contains many variability points

The execution paths are managed on the testing bed thanks to a database (which phone has GPS…)

Actions will be executed only on the targeted phones.Only one scenario for all the devices

Perspectives

An iterative testing process with a specialized team to enhance our tool

Emerging platforms (Tablets…)

Control the applications @runtime thanks to Autonomic Computing

A component-based programming approach to a better description of the application’s flowchart
