/**
 * Tutorial on how to add a new Ant Test unit.
 * 
 * In this case we are creating a new argument called IgnoreMethodAnnotations.
 * 
 * 1. Copy src/test/resources/ant/basic and rename the folder. In this case we rename to IgnoreMethodAnnotations.
 * 2. Make a new test unit (call it IgnoreMethodAnnotationAntTest) and extend this class.
 * 3. In test unit, set buildXmlFile = src/test/resources/ant/IgnoreMethodAnnotations/build.xml.
 * 4. Make modification to the build.xml file accordingly.
 * 5. To execute ant, call super.executeAntTarget(TARGET_NAME)
 * 6. To verify execution there are helper methods that can do verification for you.
 *      If you would like to obtain the xml document it is public groovy.util.Node dom.
