Is it a fallacy to have a 'tester goal'?

Well, I would like to have a maven goal execute-custom-tests inside my custom-maven-plugin that consists of running test methods (TestNG). Why? Basically the main objectives of the plugin are testing stuff (not unit testing) and the tests in src/test are for unit testing, right?

I know it sounds a little crazy, please show me the light. What's the right thing to do?
