Create a mock for a bank account class.

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

Set up behavior to return true, true, and then false.

import matlab.mock.actions.AssignOutputs;
when(withExactInputs(behavior.isOpen), ...
    AssignOutputs(true).then(AssignOutputs(true)).then(AssignOutputs(false)))

Use the mock.

isAccountOpen = mock.isOpen
isAccountOpen = logical
   1


isAccountOpen = mock.isOpen
isAccountOpen = logical
   1


isAccountOpen = mock.isOpen
isAccountOpen = logical
   0

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).
