What is Integration Testing?
Integration testing verifies that separately built pieces—modules, services, databases, third-party APIs—cooperate correctly when connected. It targets the seams between components, where mismatched contracts, bad data handling, and timing issues tend to hide, defects that unit tests can never catch in isolation. Integration tests sit between fast unit tests and full end-to-end journeys, offering a balance of realism and speed. Together these layers form a healthy test pyramid, with recorded E2E flows validating that everything holds up from the user's perspective.
