## Class AggregateTransformer

- java.lang.Object
- - org.apache.tools.ant.taskdefs.optional.junit.AggregateTransformer

-     public class AggregateTransformer
      extends java.lang.Object

  Transform a JUnit xml report. The default transformation generates an html report in either framed or non-framed style. The non-framed style is convenient to have a concise report via mail, the framed report is much more convenient if you want to browse into different packages or testcases since it is a Javadoc like report.
