then(action1,action2) specifies an action and a subsequent action for mock object interactions.

Input Arguments

action1 — Defined action

instance of matlab.mock.actions.StoreValue

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

action2 — Second defined action

instance of matlab.mock.actions.DoNothing | instance of matlab.mock.actions.ThrowException

Second defined action, specified as an instance of matlab.mock.actions.DoNothing or matlab.mock.actions.ThrowException.

Example: action2 = DoNothing

Example: action2 = ThrowException(MException('Account:deposit:Negative','Deposit amount must be positive.'))

Examples

Store Series of Values to Mock Property

Create a mock for a bank account class.

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

Specify behavior. Allow the IsOpen property to be set once, and then throw an exception.

import matlab.mock.actions.StoreValue
import matlab.mock.actions.ThrowException
when(set(behavior.IsOpen),StoreValue().then(ThrowException( ...
    MException('Account:setValue:tooMany','Value set too many times.'))))

Use the mock.

mock.IsOpen = false

mock = 

  Mock with properties:

    IsOpen: 0

mock.IsOpen = true

Error using matlab.mock.internal.MockContext/createMockObject/mockPropertySetCallback (line 429)
Value set too many times.

Tips

• Each call to then accepts up to two actions. To specify more subsequent actions, use multiple calls to then. For example, to specify three actions, use action1.then(action2).then(action3).
