PragmaDev Tester supports TTCN-3 international standard testing language including syntax and semantic verification, simulation, code generation, debug, and graphical traces. A video introduction to TTCN-3 is available here.

The formal models can be simulated against their related test suites. The implementation of the model can be tested against the implementation of the test suites. Traces and breakpoints can be set within the model or within the test suites and stepping is available on both sides because the bug might be in the model or in the test suite. A 10 minutes on-line demonstration is available here.

The test verdict is displayed in the debugger window and in the graphical execution trace window.

Easy implementation

The generated code architecture makes integration on target easy and straight forward. Macros are used for messages going out of the test case, and a chained list of message queues is used for incoming messages.

Model Based Testing

A key aspect of modeling is to use the model as a mean of interaction with the different stakeholders. As a result the model can be seen as a reference and the different scenarios used to validate the model are by definition nominal test cases. PragmaDev Studio can automatically convert the simulation scenarios to test cases that can be used on a real tester against the real system.

Continuous integration

TTCN-3 test suites can be used to test the model or its implementation on target. Automatic testing can be executed on whole or a part of the model or its implementation. TTCN-3 can be used for unit testing, integration testing, validation testing.

Model driven testing

Test cases can be generated automatically out of:
  • Requirements,
  • Execution traces.

Model coverage

At any time during a test session it is possible to view graphically the model coverage at any architecture level. You can see how many times a transition has been fired, how many times a state has been reached, and how many times a symbol has been executed.
