Create and Run Test Cases

To create and run test cases, model coverage provides the MATLAB® commands cvtest and cvsim. The cvtest command creates test cases that the cvsim command runs.

You can also run the coverage tool interactively:

  1. Open the sldemo_fuelsys model.

  2. In the Simulink® Editor, select Model Settings on the Modeling tab.

    In the Configuration Parameters dialog box, on the Coverage Pane, select Enable coverage analysis, which enables the coverage settings.

  3. Under Coverage metrics, select the types of coverage that you want to record in the coverage report. Click OK.

  4. Simulate the model.

    Simulink Coverage™ saves coverage data for the current run in the workspace object covdata and cumulative coverage data in covCumulativeData, by default if you simulate using the Run button. Simulink Coverage also saves these results to a .cvt file by default. At the end of the simulation, the data appears in an HTML report that opens next to your model. For more information on coverage data settings, see Specify Coverage Options.

    You cannot run simulations if you select both the model coverage reporting and acceleration options. If you set the simulation mode to Accelerator, Simulink Coverage does not record coverage.

    When you perform coverage analysis, you cannot select both block reduction and conditional branch input optimization, because they interfere with coverage recording. See Simulink Optimizations and Model Coverage for more information.
