Mock Dependencies in Tests - MATLAB & Simulink (original) (raw)

Main Content

Use the mocking framework to isolate a portion of a system to test by imitating the behavior of dependencies

When unit testing, you are often interested in testing a portion of a complete system isolated from dependencies. To test a portion of the system, we can use_mock objects_ to replace the dependencies. A mock object implements at least part of the same interface as the production object, but often in a simpler, faster, more predictable, or more controllable way.

To get started, see Create Mock Object.

Classes

Topics

• Create Mock Object
  Test a portion of a complete system in isolation using a mock.
• Specify Mock Object Behavior
  Define behavior for mocked methods and properties. For example, you can specify that a method returns predefined values.
• Qualify Mock Object Interaction
  Intercept messages sent from the component under test to the mock object. For example, you can verify that a method was called or a property was set.
• Write Tests That Use App Testing and Mocking Frameworks
  Create fully automated tests for an app by using the app testing framework and the mocking framework.
