Sandwich Testing: An Effective Integration testing process

Sandwich testing, also called as mixed testing, is a kind of integration testing process that combines top-down and bottom-up testing. With an experience in delivering sandwich testing projects custom software development services provide the best quality of the deliverables right from the development of software process. To learn more about sandwich testing, we must first understand the meaning of integration testing. Integration testing is a stage of software testing where different software modules are combined and tested as a group, rather than as an individual unit. A custom software programming expert conducts integration testing after unit testing, but before system testing. The purpose of integration testing is to verify the performance, reliability and functional requirements placed on groups of individual software modules (also called as assemblages). Black box testing is used to work out these assemblages through their interfaces. Test cases are conducted to test the correct interaction between all components within assemblages. The integration testing idea is a kind of a “building block” approach in which verified groups of software modules are added to a verified base. Sandwich Testing – a brief Sandwich testing is a vertical incremental testing strategy that tests the bottom layers and top layers and tests the integrated system in the computer software development process. Using stubs, it tests the user interface in isolation as well as tests the very lowest level functions using drivers. Sandwich testing combines bottom-up and top-down testing. Bottom-up testing is a process where lower level modules are integrated and then tested. This process is repeated until the component of the top of the hierarchy is analyzed. It helps custom software development services find bugs easily without any problems. Top down testing is a process where the top integrated modules are tested and the procedure is continued till the end of the related module. Top down testing helps developers find the missing branch link easily.
