Integration testing is a software testing technique in which individual modules or components of an application are tested together as a group to ensure they work correctly when integrated. It focuses on verifying the interfaces and data flow between modules.
The main goal of integration testing is to detect defects in interactions between modules, such as incorrect data passing, interface mismatches, or communication errors. It is performed after unit testing and before system testing.
Integration testing can be done using approaches like Top-Down, Bottom-Up, or Big Bang, and it helps ensure that the overall system functions as intended when all components work together.
