Determine the various levels of testing
The following are various levels of testing:
Large systems are built out of subsystems which are made up of modules, modules of functions andprocedures. Thus in large systems, testing is performed at various levels such as unit level testing, module level testing, system level and subsystem level testing.
Hence testing is performed at below levels. In all levels, testing are performed to check interface integrity, performance, information content.
Bottom-up integration This testing starts construction and testing with the components at the lowest levels in the program structure.
Function count:- It measures the functionality from the user point of view, that is, on the basis of what the user requests and receives in return. Therefore it deals with the fun
