In Software testing, it is important that every system component gets integrated with the different application modules. Though each of the software modules is unit tested, there are critical chances for the modules to have defects
Significantly, system integration testing is taken up to effectively verify the various interactions between modules and also verifies the low-level and high-level software requirements as given in the software requirements specifications document. Some of the main situations when Integration testing should be taken up: • When any new changes are made to the application requirements, then this may require integration testing as the new changes may not be unit tested • Integration testing becomes necessary to understand the logic implemented by the developer against the requirements What are the benefits businesses get with Integration Testing? With integration testing, most of the test cases are written at the early stage and thus helps to perform execution on every build. This testing process tackles the bugs related to exception handling and validates the performance, functionality, and reliability of the integrated modules. Some of the other benefits include:• Simplifies the integration among different application modules • Identifies system-level issues such as integration mistakes, broken database and helps to resolve them at the earliest • Assures in interacting with other third-party tools and APIs • Bugs are identified and resolved at the early stage • Improves the overall development and production time What are the important Integration Testing approaches businesses should know? Big Bang Integration Testing:In this approach, almost all of the units or major units are combined together to perform integration testing in one attempt. Usually, this method is practiced when teams have entire software in their bundle.
