Examples Of Stubs And Drivers — In Software Testing

A "Login" module that needs to verify credentials against a "Database" module. The Problem: The Database module isn't finished yet.

Create a Stub for the Database. When the Login module calls checkUser() , the Stub simply returns true (success) without actually searching a real database. This allows you to verify if the Login module correctly redirects the user to the dashboard. 2. Drivers (The "Calling" Program) Examples Of Stubs And Drivers In Software Testing

It is passive; it waits to be called and returns hardcoded or predefined data. Example Scenario: A "Login" module that needs to verify credentials

Primarily used in Top-Down Integration Testing . When the Login module calls checkUser() , the

In software testing, and drivers are "mock" components used as temporary replacements for modules that are not yet developed or available. They are essential for incremental integration testing , allowing you to test specific parts of a system in isolation. 1. Stubs (The "Called" Program)

A stub is a dummy module that simulates a . It is used when the main module is ready for testing, but the sub-modules it depends on are still being built.
