Test stub (original) (raw)

In advanced polymorphism computer science, test stubs are programs that simulate the behaviours of software components (or modules) that a module undergoing tests depends on. Test stubs provide canned answers to calls made during the test, usually not responding at all to anything outside what's programmed in for the test. They are mainly used in incremental testing's top-down approach. Stubs are computer programs that act as temporary replacement for a called basin module and give the same output as the actual product or software.
