Hi Dhani
System testing is related totesting the functionality of testing and where as integration testing i reslated to testing of combine the programs developed by different programmers and checking the difference in code , for the modified one and the unmodified one

Say,

I have Project-A, in that, I have Module-A and Module-B.
Module -A has Program-A and Program-B
Module -B has Program-C and Program-D

If 4 people got changes, on Program-A, Program-B, Program-C, Program-D respectively,

Testing Program-A is called Unit testing.
testing Module-A is system testing
Testing Project-A is integration testing.

Hope I am clear..

Hi jagdish,

I got new doubt because of "kgumraj" post!!!

As per my knowldge below is info.

Testing Program-A is called Unit testing.
Testing Module-A is Moduke testing
Testing Project-A is integration testing.

System testing is nothing but to test fusiability, funtionality, performance and security of the whole devaloped application.

If i am wrong please let me know?

Thanks,

post from kgumraj was perfect. Just putting it in a diff way.

Say my application has got 50 programs and the Output of my application is the input to say application 2.

Me testing my code fix in my application - Unit testing

The system test team testing my appl ( with all programs) - System testing . The only diff would be in the environment and the test set-up.

Testing all the applications together - Integration testing. ( Application 2 wud be tested with application 1 o/p .....)

Hope this helps

To understand that we need to know the flow of testing.
1) Unit - done by developer to test the SPECIFIC piece of code he has written
2) Integration - Done by dev. to ensure that the changed module works well with other modules.
3)system- done by tester to ensure the functionality is correct.
4) regression - done by tester to ensure EXISTINg func. doesn't change
5) UAT - done by business to see bus. reqs are met.
