Integration testing is a type of testing conducted to evaluate the interfaces and interactions between

different modules of source code. Here’s why integration testing is the correct choice:

Definition: Integration testing focuses on verifying that the modules or components of an application

work together as expected. It checks for data flow between modules and ensures that integrated

units function correctly.

Scope: Unlike system testing (which tests the entire system) or component testing (which tests

individual components), integration testing specifically targets the interactions and interfaces

between modules.

Purpose: The goal is to identify issues that arise when combining components, such as incorrect data

exchange, communication errors, and interface mismatches.

Reference: "Software Testing Techniques: Integration testing is crucial for ensuring that different

parts of an application work together correctly, focusing on the interfaces and interactions between

modules." (IEEE Software Testing Standards)
