Detailed explanation-1: -Bottom-up The strategy of integration testing is to test the lowest level components first. The tested modules are then utilized to help with the testing of higher-level modules.
Detailed explanation-2: -What are top down and bottom up integration testing? Top down integration testing involves designing the main module first, then calling submodules from it, whereas a bottom up integration testing approach involves creating different modules first, then integrating these modules into the main function.
Detailed explanation-3: -Top-down integration testing is an integration testing technique used in order to simulate the behaviour of the lower-level modules that are not yet integrated. Stubs are the modules that act as temporary replacement for a called module and give the same output as that of the actual product.
