testing a small part of the application is called unit 
testing.

The Unit Testing is done by the Devlopers before giving to 
the Testers.

testing each and every microfield of an application is 
called unit testing

testing each and every microfield of an application is 
called unit testing

unit testing is a process carried out by the developers 
where basic units are given to the application and tested

Testing of each and every  part indivdually called Unit 
Testing. Unit Testing is done by Developers before giving 
the application to Testers.

During this phase Developers will verify the correctness of 
a single component.

It is also called as Module or Component testing

Testing an Individual program or component is known as UNIT
TESTING (or) MICRO TESTING. (or) PROGRAM TESTING.
This type of testing is undertaken by Developers.They will
test for the program correctness
It is classified into 3 types:
(i)Execution Testing
(ii)Operation Testing
(iii)Mutation Testing (Mutation means Change)

i)Verifying the logic of the program.(statement
coverage,loop coverage,conditional coverage,programme
technique coverages)
ii)Checking whether the program is running on the customer
expected platform(ie OS,Compilers,Browser etc.)
iii)To check whether the program is responding to the
changes or not.
