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

unit testing conducted by development people conducted on 
single module

combining all the induvidul module to from a uniqe module 
is known as unit testing

Unit testing doing by developer.  It is first level of
dynamic testing.  Developer test build one module.

waht is a unit testing ?
why be needs of unid testing.
and define the terms of unit testing or function.

Unit testing is a verification effort on the smallest unit 
of the software design the software component or module

Unit testing is a verification effort on the smallest unit 
of the software design the software component or module

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.

Functional and reliability testing in an Engineering 
environment. Producing tests for the behavior of components 
of a product to ensure their correct behavior prior to 
system integration.

unit testing is typically done by the developer
this is used to test the small unit of the code or micro 
unit of the code
this can be done after developing the code
developer needs to follow the following points in unit 
level testing
1)Logic
2)Coding Conventions
3)Reusability
4)Standards

Unit testing
   
       In which the individual unit of the s/w are 
tested.to show that indidual parts are corect..
       It is done by the developer
       unit testing is also called component teting, module 
testing, program testing, Isolation testing

thanks

Testing of Small module of a Project is called as unit
testing, it's the work of Developer....

It is defined as an intial level of testing in which once 
the unit’s developed it will be tested for its 
correctness,if it justify the requirements
it belongs to whitebox tetsing and is done by developers.
