Answer / mahesh
At Coding Stage, programmers are verifying the internal
structure of every program with the hwlp of white box
testing techniques
Balck box type testing geared to functional requirements of
an application; this type of testing should be done by
testers. This doesn't mean that the programmers shouldn't
check that their code works before releasing it(which of
course applies to any stage of testing)

Answer / yauri
I'd like to add more explanation about unit testing here as following:
unit testing is whitebox test which is used to test the single piece of code or module (commonly it will be a method of a class). But, in unit test, we are suppose to not using the high resource (e.g. database, web service, etc) and even we don't need to start the server (whole of the application). So, if there's a dependency with the secondary object (a.k.a collaborator), we can use "Test Double" technique (either Dummy, Fake, Stub, Mock). Usually i use Mock objects (e.g. mockito, power mock, easy mock, etc) to replace the real object for testing purpose.
And please notice that basically we can do the unit testing either after writing the production code or before writing any production code.
In extreme programming, we will write the unit test first before write any production code (read Uncle Bob's book ^_^). Commonly it recognized as "Test Driven Development".
