What is the main goal of integration testing?

The main goal of integration testing is to examine the units or modules as one integrated system. This phase of testing occurs after individual components have been thoroughly tested during unit testing. In integration testing, the focus shifts to how these components work together when combined, ensuring that the interfaces and interactions between them perform as expected. This step is crucial because it helps identify issues that may arise during the interaction of multiple components, which might not be evident when modules are tested in isolation.

Successfully conducting integration testing helps ensure that the system as a whole behaves as intended and meets its functional requirements. By validating the integrated components, the testing process verifies that they collaborate correctly and handle data exchanges appropriately, which is essential for the reliability and effectiveness of the complete system.
