Stubs

In software integration testing, stubs are components or modules that simulate the behavior of natural components or dependencies. Stubs replace components or modules that are external to the unit being tested. The primary purpose of using stubs is to create a controlled testing environment and to isolate the unit under test from its external dependencies. Stubs provide simple predefined responses to requests made by the unit being tested, allowing developers to verify that the unit integrates correctly with its dependencies.

Here are some key concepts related to the use of stubs in integration software testing:

• Stub definition: A stub is a minimal implementation of a component or module that provides predefined responses to calls being tested by the unit. It is a temporary replacement for the actual component to isolate the unit under test during integration testing. Stubs help create a controlled environment for testing and allow the unit under test to interact with...
