Integration Testing: It is nothing but testing the
communication between the modules. It is done on the basis
of HLD (high level design )Document.
Top down Approach: It is nothing but, checking the
communication between the Main Module to the Sub module.
Example: If A, B & C are three Module, Assume A is the
main module and B, C are the sub modules. Checking the
communication from main module (A) to sub modules B & C are
nothing but Top down approach.
Stub: In above example..assume that, if Submodule B is
under construction. At that time, the Developer take the
help of a Temporary program (called as Stub) to check the
communication between the modules.
Bottom Up: It is, checking the communication between the
Sub Module to the Main module.
Driver: In above example..assume that, if Main module A is
under construction. At that time, the Developer take the
help of a Temporary program (called as Driver) to check the
communication between the modules.
Hope this will help...
