The first thing needed is defining where the test classes should be in. After that, the TestNG XML file must be created to run the tests. Each package has a XML file to run all package tests. In addition, an entry for each test package is needed in the file src/main/java/testng_conformance.xml.

In the tests/examples folder of the project (named EasyBeans by default), there is a TestNG XML file example called testng_xml:

<!DOCTYPE suite SYSTEM "http://beust.com/testng/testng-1.0.dtd">
<suite name="Test Suite Example" verbose="1">
  <test name="Test Example">
    <packages>
      <package name="org.ow2.easybeans.tests.examples"/>
   </packages>
 </test>
</suite>
