To support the execution of the User service level test, we need another helper file. This file (attached at the end) is called FOPHelper.java and lives in src/service/**/fop.
Add the following imports and method to UserManagerTest.java:

Now execute ant test-service. The testGeneratePDF method will execute and generate the 3 files involved in the PDF generation
process. user.xml, user.fo and user.pdf (all three attached at the end of this tutorial).
You should see output:
{{{
