Answer Posted / sitam jana
Bottom up integration testing is an incremental approach to integration testing where the lowest level components are tested first,and then used to facilitate the testing of higher level components.
Top down integration testing is an incremental approach to
integration testing where the component at the top of the
component hierarchy is tested first, with lower level
components being simulated by stubs. Tested components are
then used to test lower level components.
