Integration testing and functional testing are both crucial aspects of the software testing process, but they focus on different aspects of ensuring software quality.
Functional testing is a type of testing that verifies whether each function of the software application operates in conformance with the requirements specifications. It is primarily concerned with the behavior of the system under test and checks if all functionalities work as intended. For example, if a software application has a login feature, functional testing would involve entering valid and invalid credentials to ensure the login works as expected and handles errors appropriately.
Integration testing, on the other hand, is the process of testing the integration or interfaces between components or modules of the software application. It aims to detect any issues that arise when different modules interact with each other. For instance, if an e-commerce application has a module for processing payments and another for managing inventory, integration testing would ensure that when a customer places an order, the payment is processed correctly, and the inventory is updated accordingly.
In summary, functional testing focuses on individual functionalities working correctly in isolation, while integration testing ensures that different components of the system work together seamlessly.
