testing of virtually any software. Junit testing is accomplished by writing
test cases using java, compiling these test cases and running the resultant
classes with a JUnit Test Runner.<o:p></o:p></span></div>

unit testing in general. What and how much to test depends on how important it
is to know that the tested software works right, in relation to how much time
you are willing to dedicate to testing. since you are reading this, then for
some reason you have decided to dedicate at least some time to unit testing.<o:p></o:p></span></div>

An
SMTP server needs to handle email address of the format specified in RFC
documents. To be confident that my SMTP server compiles with the RFC, I need to
write a test case for each allowable email address type specified in the RFC.
In the RFC says that the character “#” is prohibited, then I should write a
test case that sends an address with “#” and verifies that the SMTP server
rejects it. You don’t need to have a formal specification document to work
from. If I wasm’t aiming for compliance, I could just decide that it’s good
enough if my server accepts email address consisting only of letters, numbers
and “@”, without caring whether other addresses succeed or fail.<o:p></o:p></span></div>

everything is better if you make your tests before you implement the features.
For my SMTP server, I did some prototyping first to make sure that my desing
will work, but I did not attempt to satisfy my requirements with that prototype.
I am now writing up my test cases and running them against existing SMTP server
implementations(like Send mail). When I get to the implementation stage my work
will be extremely well defined.Once my implementation satisfies all of the unit
tests, just like send mail does then my implementation will be completed.<o:p></o:p></span></div>

<span style="font-size: 16.0pt; line-height: 115%;">Ant is an open source build
technology developed by Apache intended to build processes in Java Environment.
It is a similar kind of tool like make, but it does not use shell commands to
extend the functionality. The use of shell commands in make brings about the
integrity with other languages too but this also makes it platform specific. In
contract, Ant is based on XML and uses java classes in automatic generation of
build processes that makes it platform independent. It is applicable to any
integrated development environment (IDE) that uses Java. A build file is
generally named as build.xml.<o:p></o:p></span></div>
