Create a strict mock for a bank account class.

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

Set up behavior to return empty once and then true.

import matlab.mock.actions.ReturnStoredValue
import matlab.mock.actions.AssignOutputs
when(get(behavior.isOpen),ReturnStoredValue().then(AssignOutputs(true)))

Use the mock.

isAccountOpen = mock.isOpen
isAccountOpen =

     []
isAccountOpen = mock.isOpen
isAccountOpen = logical
   1

isAccountOpen = mock.isOpen
isAccountOpen = logical
   1

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).
