Integration Testing | QA Testing Service | BetterQA For example, if the system under test is a web application, system-level tests would focus on the interface between the web application and the web server. Drivers are used as a temporary module for integration testing. Bottom up integration also uses test drivers to drive and pass appropriate data to the lower level modules. Each method has its advantages and disadvantages and we will discuss them all in detail. These units are frequently referred to as utility modules. A simple guide on how to perform system integration testing Bottom Up Integration Testing Approach - Professionalqa.com Example of a black-box integration test An example of a black box test in this context could be, testing the integration of a vehicle finance system with an external credit referencing agencies system, in particular, making sure that the XML feed from the external agencies system integrates with your system. Answer: In the bottom-up integration testing, every module at lower levels is tested with higher modules until all modules are tested. Lowest level modules are tested first and then high-level modules and finally integrating the high-level modules to a low level to ensure the system is working as intended. We are concerned about its quick output. Bottom up Integration Testing 4. Stubs are used for testing if some modules are not ready.
