Class: matlab.mock.actions.AssignOutputs
Namespace: matlab.mock.actions

Action for mock object interaction or action subsequent to defining return values

Syntax

then(action1)
then(action1,action2)


Description

then(action1) specifies an action for mock object interactions.

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

Input Arguments

action1 — Defined action

instance of matlab.mock.actions.AssignOutputs

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

Example: action1 = AssignOutputs(true)

Example: action1 = AssignOutputs(7,13,42)

action2 — Second defined action

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

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

Example: action2 = DoNothing

Example: action2 = ThrowException

Examples

Assign Series of Outputs to Mock

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).
