Step-based test sequences, external data sources, signal authoring, automatic test case generation

You can develop test scenarios by authoring input data, mapping external data to your test cases, or automatically generating inputs using Simulink® Design Verifier™:

  • Create a template MAT-file or Excel® file from your model and add values.

  • Place a Signal Editor block in the system under test and author inputs graphically.

  • Map MAT- or Excel files to the system under test.

  • Create a test directly from data contained in an Excel files. For more information, see Use External Excel or MAT-File Data in Test Cases.

  • Generate test inputs Simulink Design Verifier to extend coverage or replicate design error conditions. Add the generated tests to your test file.

You can also author test inputs that react to simulation behavior by using a Test Sequence block. Define sets of steps and transitions by using MATLAB® as the action language. You can use sequential or switched step groups in a hierarchy. Create test sequences in a Test Sequence block.
