Crap 4J not running my tests

[Crap4j]

Hi,

I am using Eclipse 3.4.2 ganymede and installed the Crap4j plugin via
the update site. I am able to see the Crap 4j icon in eclipse and when
I try launching it, I am getting an error message saying,

No tests found. Is the project built? and the detailed message says,

Plug-in Provider: Agitar Software
Plug-in Name: Agitar Test Runner
Plug-in ID: com.agitar.eclipse.testrunner
Version: 2.1.2.000677

I am new to Crap 4j, any help on this will be appreciated.

Thanks,
Vijayan.
