Is there a way to use fatalAssert statements in CustomCriteria or Clean-Up Callbaks ?

Hi

I'm trying to somehow customize the execution of a testfile, meaning if a certain test case fails, then it shoul not go any further, for example if I get an error while setting up a power supply then there is no reason in continuing.

I was attempting to use the fatalAssertFail statement or something similar for this in the Custom Criteria section, but I get an error statment that fatalAssertions and Assumptions are not allowed.

I tried experimenting with the code below in the Custom Criteria section of the Simulink Test Manager :

% no postprocessing

import matlab.unittest.TestCase;

import matlab.unittest.constraints.*

import matlab.unittest.qualifications.QualificationEventData

import matlab.unittest.qualifications.FatalAssertable

PSU = true;

test.fatalAssertReturnsTrue(PSU,'PSU passed')

The error code is :

-------------------------------------------------------------------- Fatal Assertion and Assumption qualifiers are not supported. Use Verification and Assertion. --------- Error ID: --------- MATLAB:unittest:FatalAssertable:FatalAssertionFailed -------------- Error Details: -------------- Fatal assertion failed.

How is the fatal Assert intended to be used ? Or what are the limitations ?

Thanks in advance

Hello,

No, “fatalAssert” statements cannot be used in Custom Criteria or Clean-Up Call-backs in MATLAB. “fatalAssert” statements are intended to immediately terminate the test case execution upon failure and report the failure as a fatal error. This is not suitable for use in Custom Criteria or Clean-Up Call-backs, as they are not expected to terminate the test case execution.

Instead, you can use “assert” or “verify” statements with appropriate qualifiers in your Custom Criteria or Clean-Up Call-backs.
