What is the primary objective of conducting interface testing?

The primary objective of conducting interface testing is to ensure that modules meet interface specifications. This type of testing focuses on the interactions and data flow among different modules or components of a system, confirming that they communicate as intended according to predefined specifications. By validating the interfaces, teams can identify issues such as data type mismatches, errors in data transmission, and miscommunications between modules, which can lead to functional failures or performance problems within the application.

Ensuring compliance with interface specifications is critical in application development, especially in complex systems where multiple components work together. When modules are correctly interfaced, it minimizes the risk of errors propagating through the system and enhances overall system reliability and maintainability. This testing is essential for identifying potential integration problems early in the development lifecycle, allowing for timely corrections before deployment.

Other options address different aspects of software development and application performance but do not directly focus on the specific aims of interface testing. Improving user interface design pertains more to user experience enhancements rather than validating module interactions. Validating data security protocols is crucial but falls under security testing rather than interface testing specifically. Increasing overall application performance relates to system efficiency and optimization practices rather than ensuring correct module communication.
