Behavior of the mock, specified as a matlab.mock.PropertySetBehavior instance. To create an instance of matlab.mock.PropertySetBehavior, call the matlab.mock.PropertyBehavior.set or matlab.mock.PropertyBehavior.setToValue method with the behavior object.

Example: set(myMockBehavior.MyProperty)

Example: setToValue(myMockBehavior.MyProperty,13)

Defined action, specified as an instance of matlab.mock.actions.StoreValue, matlab.mock.actions.DoNothing, or matlab.mock.actions.ThrowException.

Example: StoreValue

Example: ThrowException(MException('Account:deposit:Negative','Deposit amount must be positive.'))

Create a strict mock for a person class. The mock has one property, Name.

testCase = matlab.mock.TestCase.forInteractiveUse;
[mock,behavior] = testCase.createMock('AddedProperties',"Name",'Strict',true);

Set up the behavior. When the property is set, store the value, and when the property is accessed, return the value. Without defining this behavior, strict mocks throw an exception when setting or accessing the property.

import matlab.mock.actions.StoreValue
import matlab.mock.actions.ReturnStoredValue

Set the property. The property access is implicit because we are displaying the result.

mock.Name = "David"
mock = 
  Mock with properties:

    Name: "David"
