Reactis is used in a model-based design process using Simulink/Stateflow models. Reactis is a standalone application that reads the .mdl/.slx files produced by the MathWorks environment.
Reactis contains three core components:
| Tester | Simulator | Validator |
|---|---|---|
| It provides automated test generation from models. | It enables you to visualize model execution to debug models and track coverage. | It offers automated checks of Simulink models for violations of user-specified requirements. |
Tester
Reactis Tester offers automatic test generation from Simulink models. The generated test suites provide comprehensive coverage of different test coverage metrics – including the Modified Condition/Decision Coverage (MC/DC) test coverage measure while at the same time minimizing redundancy in tests.
Reactis Tester enables engineers to maximize the effectiveness of testing while reducing the time actually spent on testing.
Each test case in a test suite consists of a sequence of inputs fed into the model as well as the responses to those inputs generated by the model. The automatically generated test data may then be used for a variety of purposes, including the following:
- Implementation conformance. The tests may be applied to source-code implementations of models to ensure conformance with model behavior.
- Model testing and debugging. The tests may be run on the models themselves to detect runtime errors and to study and revise model behavior.
- Regression testing of models. The tests may be run on a new versions of models to flag differing behaviors in new versions.
- Reverse engineering of models from source. Tests may be generated from models derived from legacy code in order to check conformance between model and legacy code.
Simulator
Reactis Simulator enables you to visualize model execution and debug Simulink® models. Simulator’s user interface is similar to those of traditional debuggers from programming languages; it allows you to:
- Execute a block, single step, or multiple steps at a time.
- Make a reverse execution.
- See data values, hover with the mouse, open a scope, or add to watched variables.
- Discover unexercised parts of a model, highlighted in red.
- Generate detailed coverage reports.
- Use Breakpoints.
Validator
Reactis Validator performs automated searches of models for violations of user-specified requirements.
If Validator finds a violation, it returns a test that leads to the problem.
This test may then be executed in Reactis Simulator to gain an understanding of the sequence of events that leads to the problem. Validator enables the early detection of design errors and inconsistencies and reduces the effort required for design reviews.

C Plugin
Reactis also offers an useful C Plugin; it integrates seamlessly with Reactis to offer white-box testing and validation of the C-code portions of models (S-Functions and calls to C from Stateflow).
By automating testing and validation of C code within the same environment that tests your Simulink and Stateflow, the Reactis for C Plugin enables you to do more thorough analysis of your C code much more quickly.
