/**
 * ShrinkWrap {@link EnterpriseArchive} builder for CDI TCK Arquillian test. This builder is intended to provide basic
 * functionality covering common TCK needs. Use shrinkwrap API to adapt archive to advanced scenarios.
 * <p>
 * Test classes are added to EJB module.
 * </p>
 * <h2>Default and custom web module</h2>
 * <p>
 * The default web module is defined in order to build portable EE archive - it has to contain Class-Path entry in the
 * MANIFEST.MF to state module dependency (see Class Loading Requirements in Java EE spec). Custom web module is not supported
 * directly however its possible to build such module with shrinkwrap API and add it to final enterprise archive. It is
 * necessary to omit default web module using {@link #noDefaultWebModule()} as long as custom web module is used since
 * arquillian cannot handle in-container test packaged as EAR with multiple web modules at the moment (cannot determine which
 * web module to enrich).
 * </p>
 * <h2>application.xml</h2>
 * <p>
 * The <code>application.xml</code> descriptor is not supported as it is no longer required (Java EE 5, Java EE 6). Use
 * shrinkwrap API to add custom <code>application.xml</code> descriptor.
 * </p>
 * <h2>Use case</h2>
 * <p>
 * Use enterprise archive in TCK tests only while:
 * </p>
 * <ul>
 * <li>explicitly testing EAR structure</li>
 * <li>testing Java EE full profile (e.g. EJB timer service, MDBs)</li>
 * </ul>
 * <p>
 * Tests that use {@link EnterpriseArchiveBuilder} must belong to {@link TestGroups#JAVAEE_FULL} group.
 * </p>
