[Axis2] unit tests

[damitha kumarage]

Hi all,

I have added a main test suite to test unit tests of all the modules at > e
in test/unit folder

https://svn.apache.org/repos/asf/webservices/axis2/trunk/c/xdocs/axis2_deve=
loper_guide.html

It is good if we all can maintain unit tests throughtout the development an=
d

make all the tests pass before we commit the code

cheers
