Autogeneration of test architecture Test architecture:

Defines the architecture of the test environment

TestContext diagram: Defines the system under test (SUT; one or more), TestComponent objects and their

interconnections

Once we have a TestContext, we can proceed with test cases Since test cases are operations of the test context, the test cases can access both

the TestComponents objects and the SUT objects

support fine-tuning

Model includes all requirements and design rationale so it’s readily understood

Validation suite can be made available professional services

Facilitates scaling down for smaller footprint applications Pick and choose only the necessary components

Customize components

Facilitates certification of the framework such as DO-178B Scalable—helps ensure that you include only the components you need; no

Agile and Rhapsody Model-Driven Development for embedded systems development


65

Agile software principles Implementation versus exhaustive planning and documentation

Iterative, incremental development and testing of working parts of the design completed quickly

Team collaboration with customers and business stakeholders

Responsiveness to ever-changing requirements, virtually any time in the development cycle


66

Challenges facing developers Poor communication with customer on code level alone

Some documentation is still required

Valuable diagrams are created during meetings that are discarded and later needed

Target hardware may not be available for early prototyping

Managing changing requirements

Increasing productivity while design complexity increases

More documentation required for embedded systems

Collaboration with large teams, often located globally

Long learning curve for new team members Maintenance of long life products is difficult with staff changes


67

Rhapsody Model-Driven Development Model-Driven Development helps developers capture the design using

graphical models Visualizing design concepts increases understandability

Use Object Management Group UML or a DSL

Achieving the benefits of both Model-Driven Development and Agile requires the model and code to be the same


68

Agile and MDD with Rhapsody Rhapsody enables graphical programming of the working application

while documentation is automatically generated

Empowers individuals to work the way they want to get the job done the way they know how at either the code or model level

Work in an iterative, incremental development fashion producing working parts of the design in short time frames while executing and validating each part on target or host

Enable team collaboration with customers and business stakeholders via graphical models and prototypes as opposed to code based designs

Ability to respond to ever-changing requirements, virtually anytime in the development cycle using dynamic links to requirements and automatic graphical differencing and merging


69

Customers and stakeholders provide feedback
