How Integration Testing Work In Software Development Lifecycle?

Category: Technology

Appsierra Testing different modules of an application or software together is called Integration Testing. The primary idea of this step in SDLC is to ensure that the communication between the dependent modules of software goes smoothly without any weaknesses. The ideal time for this testing procedure is usually after the completion of Unit testing and before the Validation testing of the application lifecycle. As a matter of interest, other popular names for this testing methodology are “String Testing” and “Thread Testing”…..Learn more How does Integration Testing work? The basic ideology for this testing procedure is to combine unit-tested modules and integrate them as a single system and execute tests over them. The ideal steps to follow are listed as below: 1. Have a test integration plan ready in hand. 2. Based on the project’s need, decide on which integration testing approach to go for. 3. Prepare test case scenarios, test plans, and scripts accordingly. 4. Deployment of the chosen integrated modules and executing test cases. 5. Tracking the test run reports and analyzing the defects. 6. Repetition of the above steps till the entire system is tested. Also, one can make use of the docker commands and docker-compose systems in integration testing to make in-memory databases replaceable. In such testing scenarios, these commands are proven to be very helpful…..Learn more Integration Testing Types Now that we know how the integration testing is performed, the next step ahead is knowing the different variants or approaches available. Big-Bang Integration Testing This is known to be a very basic approach to the integration testing method. In this, all the modules of a system are combined and deployed for running tests over them. However, it is only suitable for small systems as in otherwise scenarios the time taken for the deployment of the combined modules will be significantly high…..Learn more Bottom-Up Integration Testing Here the testing starts from the lower-level modules of the system and gradually moves towards the high-level modules. The primary purpose of this methodology is to identify the error right away and fix it in minimal time….Continue reading
