What is unit testing.

[Chuck Tomasi]

Unit testing allows you to do testing on discrete functions to ensure the inputs and outputs behave as expected. A unit test should be repeatable to check the behavior any time a new requirement or adjustment is made.

This may help.

Unit testing utility

Hi Kishore ,

Unit testing is the process in which each and every part of development are individually and independently scrutinized for proper operation as per the the User Acceptance.

Testing process can be different for different engagement.

Then thing which we are following is   once the development is done.

Development complete -> peer review in same development environment   ->Unit testing in Different QA environment -> UAT testing in different enviroment -> after successful completion of all mentioned things doors are open to Production.

for UT we are having different team were proper testcase are prepared and after discussing with Product owners acceptance criteria are created and piece of development done were tested   so that things done are within the scope and working as expected.

To avoid unnecessary updates to move into upper instance also UT is done.
