itests: There are no tests to run

[venu reddy]

I am trying to execute itests from itest folder with mvn. Everything went
fine without any errors including the sample itest that we are trying to
write. However I have observed that, while trying to execute itests from
each itest folder, for few folders it says "There are no tests to run". What
does this mean, are those tests incomplete?, or am I missing something
here?.
Thanks, Venu.
