Development of software has seen a terrific growth in the last couple of years or so. In the world of computer software development, massive advancement has been seen – thanks to custom software programming endeavors carried out globally.

In the software testing segment also, various approaches have been taken – sandwich resting being one among many. Sandwich Test can be best defined as an incremental middle layer software testing approach wherein you conduct tests on both the top-down (stubs) and bottom-up (drivers) levels, followed finally by a test of the integrated system. The process of Sandwich Testing starts off with an isolated testing of the user interface using stubs or called program. From there you move on to the bottom level function testing using drivers or calling program. Once the integration of the entire system is complete, you can conduct the final set of tests in the middle layer ensuring a firm grip towards customer software development.
