What is the difference between Integration Testing and
System Testing ?

Answer Posted / uday kumar. a

Integration testing means, testing the interface between
two or more modules(internal interfaces) or interfaces with
other systems(external interfaces). So in integration
testing, we will test for the interfaces. From the testing
point of view, integration testing is black box testing
appraoch, but if the documents for the functionality is not
clear, then we will go through the code and test for the
functionality.
System testing comes after Unit, Component, Intergration
testing is completed. This is the last chance for finding
the defects at the offshore, means we wil built-up the
total system at offshore and test the total system before
giving to the client.System testing includes both
functional testing and non-functional testing. The input
for integration testing is design documents and functional
documents, whereas for system testing ,the input is user
requirement document.
