MATLAB: How to identify the last active step of a test sequence when the test run stopped (because of reaching a defined stop time) using Simulink Test R2020a

simulink test

When I run my tests using the Simulink Test Manager, there are some situations where my tests get finished because the stop time of the test case has been reached. When this timeout happens, I would like to know which was the active step right before the test stopped due to the stop time. That way, I could know where my test got stuck and why it needed a timeout to finish the test.

Is it possible to export the last step of my test sequence once it finishes?

To identify the last active step you could track the active steps in general. So you can evaluate after the simulation, which one was the last active step. To do so:

1) get the active step output through the Test Sequence block's property/option "Create data to monitor the active step"

(This option is also mentioned on this documentation page: https://www.mathworks.com/help/releases/R2020a/sltest/ug/connecting-blocks-for-verify-statements.html)

2) log this output signal of the Test Sequence Block, like:

3) analyze which was the last step (in the command window):

as = get(out.logsout,('Active_Step'))

as.Values

as.Values.Data

%or

%as.Values.Data(end)

MATLAB: I am using the test manager to run the tests in a model. In the Test Sequence editor I make a call to the following code as the last step. coder.extrinsic(‘bdroot’); coder.extrinsic(‘set_param’); set_param(bdroot, ‘SimulationCommand’, ‘stop’);

You must have an output of the Test Sequence block to a Stop Simulation block and have the Test Sequence block change the output to true when you want the simulation to stop.

Here are some steps:

1. Initialize a output variable to false in the Test Sequence block

2. In your proposed step in the Test Sequence block, change this output variable to true.

3. Connect this output to the Stop Simulation block, so that the Simulation is stopped by the Stop Simulation block.

MATLAB: How to query the enumeration name for a Test Sequence block’s active step output

It is possible to get/set the ActiveStepEnumName from one of the properties of the ActiveStepDataSymbol.

For example, to read it's value:

p = sltest.testsequence.getProperty('model/Test Sequence');
s = sltest.testsequence.readSymbol('model/Test Sequence', p.ActiveStepDataSymbol);
enum_name = s.ActiveStepEnumName

To set it's value:

p = sltest.testsequence.getProperty('model/Test Sequence');
sltest.testsequence.editSymbol('model/Test Sequence', p.ActiveStepDataSymbol, 'ActiveStepEnumName', 'NewEnumName')
