What type of test is performed to ensure that individual components of a system interact correctly when tested together?

An integration test is specifically designed to evaluate how well individual components of a system work together as a cohesive unit. The primary goal of this type of testing is to identify interface defects and issues that may arise when combining various modules or components that have been individually tested in isolation.

During integration testing, different parts of the system are combined and tested as a group. This helps ensure that the interactions between individual components function correctly and that data flows seamlessly through the system. By focusing on the interactions and communication between components, integration testing addresses issues that may not be evident during unit testing, where components are evaluated independently.

This type of testing is critical in identifying problems such as incorrect data formats, mismatched interfaces, or other potential conflicts that can occur when integrating multiple components into a single functioning system. Ultimately, integration tests help ensure the entire application operates as intended when various components are put together, contributing to the overall quality and reliability of the system.
