Integration testing is an essential part of the software testing process. It focuses on testing the integration between different software modules or components to ensure that they function correctly when combined. This type of testing helps identify any defects or issues that may arise due to the interaction between these modules.
During integration testing, the individual modules are combined and tested as a group. This allows testers to verify that the modules communicate effectively, exchange data correctly, and work together seamlessly. Integration testing helps uncover any errors or faults that may occur in the interfaces or interactions between these modules.
One of the main objectives of integration testing is to ensure that the integrated system or software functions as intended. It helps validate the behavior of the system when multiple components interact with each other. By conducting integration testing, developers and testers can identify any inconsistencies, compatibility issues, or performance problems that may arise when the modules are combined.
Integration testing can be performed using different approaches, such as top-down testing, bottom-up testing, or a combination of both. It can also involve simulating real-world scenarios or testing specific integration points between modules. The main goal is to ensure that the integration of different components is seamless and functional.
