In software development, memmove is a C function that manages the movement of bytes from one memory location to another, and is commonly used in debugging operations.
Unit testing involves testing code segments individually to ensure they operate as intended and to identify and rectify potential bugs early in the development lifecycle.
This article provides various strategies for unit testing the memmove function, and recommends testing for null pointers, overlapping memory regions, and larger data volumes to ensure that the function operates correctly in a range of situations and conditions.
It also suggests several tools available for unit testing in C, including Check, CMocka and Unity, which can automate the testing process and make it more efficient.
