Software Testing Methodologies Dichotomies

Common Modeling Techniques

• Modeling Processors and Devices
• Modeling the Distribution of Components

Modeling Processors and Devices 

To model processors and devices,

• Identify the computational elements of the system's deployment view and model each as a node 
• If these elements represent generic processors and devices, then stereotype them as such, 
• If they are kinds of processors and devices that are part of the vocabulary of your domain, then specify an appropriate stereotype with an icon for each 
• As with class modeling, consider the attributes and operations that might apply to each node 

Modeling the Distribution of Components 

To model the distribution of artifacts, 

• For each significant artifact in your system, allocate it to a given node 
• Consider duplicate locations for components 
• Some components (such as specific executable's and libraries) may reside on multiple nodes simultaneously 

• Illustrate this allocation in one of the three ways: 
• ⃝Use dependency relationships, connect each node with the artifacts it deploys 
• ⃝List the component deployed on a node in an additional compartment Mention it in each node's specification which may not be shown explicitly
