Integration testing is a type of Software Testing that is used to verify the interactions and functionalities of different components of a system. It is a key part of the software development process, and it is typically performed after unit testing, which focuses on testing individual components of a system in isolation.
Integration Testing is used to ensure that different components of a system can work together seamlessly, and that they can perform the tasks that they are designed to do. This can include testing how different components of a system interact with each other, as well as testing how the system functions as a whole.
One of the main goals of Integration Testing is to identify any issues or bugs that may arise when different components of a system are combined and used together. This can include issues related to data compatibility, functional dependencies, or performance bottlenecks. By identifying these issues early on, developers can address them before the system is deployed, which can save time and resources in the long run.
Another important goal of Integration Testing is to verify that a system meets its functional and non-functional requirements. This can include testing that the system performs as expected under different scenarios, as well as testing that it is secure, scalable, and reliable.
Overall, Integration Testing is a crucial step in the software development process, and it is used to ensure that a system functions as intended and meets its requirements.
