MATLAB: Assign value to property of mock object when method is called

MATLABmocking frameworkoop

Hi, is there a way to assign a value to a property of a mock object when a method of the same object is called?
Let's say I create the following mock:
[mock, behavior] = createMock('AddedMethods', "doSomething", 'AddedProperties', "propA");
Now I would like to do something like:
when(withAnyInputs(behavior.doSomething), set(mock.propA, true));
Obviously, that's no valid code, but I think you get what I mean. Thanks for your help!

If you're using R2018b or later, you can use the Invoke action to set this up. Here's an example:
function example
    import matlab.mock.actions.Invoke;
    testCase = matlab.mock.TestCase.forInteractiveUse;
    [mock, behavior] = testCase.createMock('AddedMethods', "doSomething", 'AddedProperties', "propA");
    when(withAnyInputs(behavior.doSomething), Invoke(@setPropA));
    function obj = setPropA(obj)
        obj.propA = true;
    end
    mock = mock.doSomething;
    disp(mock);
end
