As software systems become increasingly distributed, validating how components interact is just as important as testing them individually. Integration testing focuses on ensuring that services, APIs, databases, and external dependencies communicate correctly within a system.

This testing layer plays a key role in identifying data flow issues, contract mismatches, and communication failures early in the development lifecycle. Without integration testing, teams risk discovering critical defects only after deployment, when fixes become more costly and disruptive.

By incorporating integration testing into CI/CD pipelines, teams can continuously validate system behavior and maintain confidence as applications evolve and scale.
