A test stub is a test double that provides static values to the software under test.
A test stub provides canned answers to calls made during the test, usually not responding at all to anything outside what's programmed in for the test.Fowler, Martin (2007), Mocks Aren't Stubs (Online)
A stub may be coded by hand, generated via a tool or be created as a dedicated part of a larger system such as a stub server or service.
Stubs differ from , which assert and verify interactions. Stubs only supply data.
