matlab.mock.actions.DoNothing class

Package: matlab.mock.actions

Take no action

Since R2020a

Description

Use the DoNothing class to specify that the framework takes no action when a mock object method is invoked or when a mock object property is set.

DoNothing cannot be used to set up behavior when accessing a mock object property. To specify that a mock property must not be accessed, use the matlab.mock.actions.ThrowException class.

Creation

action = DoNothing constructs an instance of the DoNothing class and returns the instance in action.

Methods

Public Methods

repeat	Repeat taking no action
then	Action for mock object interaction or action subsequent to taking no action

Examples

Take No Action When Data Type Is Invalid

Create a mock for a bank account class.

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

Set up behavior. Take no action if the IsOpen property is set to a value that is not of type logical.

import matlab.mock.actions.DoNothing
import matlab.unittest.constraints.IsInstanceOf
when(setToValue(behavior.IsOpen,~IsInstanceOf('logical')),DoNothing)

Use the mock to set IsOpen to a nonlogical value. No action is taken and IsOpen is left unset.

mock.IsOpen = 'Y'

mock = 
  Mock with properties:

    IsOpen: []

Use the mock to set IsOpen to a logical value.

mock.IsOpen = true

mock = 
  Mock with properties:

    IsOpen: 1
