Saving Simulink Model Programatically also makes a copy of a test harness

Hello,

I have a simulink model 'original_model' that has 1 test harness associated with it. That harness is saved externally and has the associated *_harnessInfo.xml file with it. The test harness has none of the "Advanced Properties" clicked such as "rebuild harness on open".

I've noticed that when I call

save_system('original_model','new_model')

it automatically generates the test harness for the 'new_model_test_harnessl.slx' and 'new_model_test_harness_harnessInfo.xml' files.

I am wondering:

1. Is there a setting for the harness I can change to keep this auto generation from happening?
2. Is there a setting for save_system I can use to keep this from happening?

Thanks for your help!

Hi,

In order to stop auto generation of test harness you will have to detach the harness form the model, follow the below steps in order to do so:

1. From the individual harness model, on the Apps tab, under Model Verification, Validation, and Test, click Simulink Test.
2. In the Harness tab, click Detach and Export.
3. In the Export Test Harness to Independent Model dialog box, click OK.
4. In the Save As dialog box, enter a filename for the standalone harness model and click OK.
5. The harness converts to a standalone model

Converting removes the harness from the main model and breaks the relationship to the main model. If a model has only one harness, its harnessInfo.xml file is deleted. If a model has more than one harness and you delete one of them, the harnessInfo.xml file is updated

Saving the model after detaching the harness should solve your problem.

Take a look at below documentation for more information.

Hope it helps!

Thanks for the comment! Unfortunately I don't want to break the relationship with the existing harness since I'll be routinely updating and changing 'original_model'.

I'm using a solution that immediatly deletes the generated harness and harnessinfo.xml.
