matlab.mock.actions.StoreValue class

Package: matlab.mock.actions

Store property value


The StoreValue action specifies that the specified value is stored when setting a property.

By default, when you set property values in strict mocks, MATLAB® throws an exception. To specify that the framework stores the value of a mock object property, use the StoreValue class.


action = StoreValue stores a property value.

Create a strict mock. By default, property interactions throw exceptions.

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

Enable set access to PropA.

import matlab.mock.actions.StoreValue;

Use the mock.

mock.PropA = 1;

Use the mock.

mock.PropB = 2;
Interactive assertion failed.

Test Diagnostic:
Unexpected set of strict mock property 'PropB'.
Assertion failed.


For a simple directive to store property values, you can use the storeValueWhen method of the matlab.mock.TestCase class. However, there is more functionality when you use the StoreValue action.
