Creating a new Testing Framework

I am trying to create a new Unit Test case framework and would like to use this along with TestNG/JUnit. So when mvn test is called, the execution thread is invokes my testing framework and tests are executed accordingly.

Or do I have to start from scratch, like Listeners and Runners as it is how in TestNG / Junit? If so, how do I plug it with a sure-fire or equivalent so that when we call mvn test, my testing framework kicks in?
