Integration Testing
Integration testing is a crucial phase of software testing in which individual software modules are combined and tested together as a group. The main goal of integration testing is to ensure that different components of an application interact with each other correctly. It focuses on verifying data flow, communication, and interfaces between modules rather than testing individual functionalities in isolation.
This type of testing is performed after unit testing and before system testing. Once individual units are tested independently, they are integrated step by step to form a complete system. Integration testing helps identify issues such as incorrect function calls, interface mismatches, and improper handling of shared data between modules.
Integration testing can be carried out using different approaches such as top-down, bottom-up, and hybrid methods. These approaches help testers validate the interaction between modules based on the project requirements. Both manual and automated testing techniques can be used depending on system complexity and testing needs.
