What Is The Main Purpose Of Integration Testing?

 The purpose of integration testing is to make sure different components or modules can work together and can make an entire system that can work successfully end to end…

A beginner who is learning software testing can understand integration testing in a very simple manner:

Example: Take an example of the Demart Ready portal…

The Demart Ready portal is divided into several key modules, including Marketing, Inventory Management, Warehousing, Supply Chain, and Customer Service. Each of these modules is developed and tested individually. However, the system only becomes complete once all modules have undergone both the development and testing phases.

After the individual development and testing of each module, the next step is to sequentially integrate them according to the specified requirements. Once all the modules are integrated, the final step is to perform end-to-end testing, which is referred to as ‘Integration Testing’ in software testing.

The goal of integration testing is to ensure that the connections between all the modules are functioning correctly and meeting the specified requirements. If the system works as expected, it’s considered complete. If not, necessary adjustments will be made during the development process to resolve any issues.

 The above diagram is a very good explanation of integration testing.
