In Integration testing method, individual software modules are taken and combined and tested as group. Integration testing done after unit testing. Integration testing identifies the issues in the interfacing between modules.
Integration testing is a software testing technique that focuses on verifying the interactions and communication between different components or modules of a software system. The objective of integration testing is to identify defects or issues that may arise when integrating multiple units together.
Integration testing, especially test driven development, is a design or implementation activity, not a testing activity.
Integration testing helps identify integration-related defects, such as incompatible interfaces, data inconsistencies, communication failures, or incorrect behavior when multiple components interact. It ensures that the system functions correctly as a whole and provides confidence in the overall quality and reliability of the software application.
