What is a key aspect of Integration Testing?

• A. Testing individual components in isolation
• B. Testing the system as a whole
• C. Testing the interaction of different parts of the system
• D. Testing for acceptance criteria

Answer: (C)

A key aspect of Integration Testing is focused on testing the interaction of different parts of the system. The primary goal of this testing phase is to identify issues that may arise when individual components or modules integrate and work together. While unit testing emphasizes the functionality of isolated components, Integration Testing is concerned with the collaboration and communication between those components to ensure they operate seamlessly when combined.

This type of testing helps uncover defects in the interfaces and interactions between integrated components, addressing scenarios that may not be evident when components are tested in isolation. By validating these interactions, Integration Testing contributes to ensuring that the entire system functions as intended when all parts are assembled.
