Description

TheReturnStoredValueaction specifies that the stored value is returned when accessing a property.

By default, when you access property values in strict mocks, MATLAB^®throws an exception. To specify that the framework returns the stored value of a mock object property, use theReturnStoredValueclass.

Construction

action = ReturnStoredValue返回存储属性值。

Methods

repeat	Repeat returning stored property value
then	Action for mock object interaction or action subsequent to returning stored property value

Copy Semantics

Return Mock 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,“严格的”,true);

Enable access toPropA.

importmatlab.mock.actions.ReturnStoredValuewhen(get(behavior.PropA),ReturnStoredValue)

Use the mock.

val1 = mock.PropA

val1 = []

val2 = mock.PropB

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

Alternatives

For a simple directive to return property values, you can use thereturnStoredValueWhenmethod of thematlab.mock.TestCaseclass. However, there is more functionality when you use theReturnStoredValueaction.
