26  * Query to find Java package roots of unit tests for Java package root of
27  * sources and vice versa.
28  *
29  * <p>A default implementation is registered by the
30  * <code>org.netbeans.modules.java.project</code> module which looks up the
31  * project corresponding to the binary file and checks whether that
32  * project has an implementation of this interface in its lookup. If so, it
33  * delegates to that implementation. Therefore it is not generally necessary
34  * for a project type provider to register its own global implementation of
35  * this query, if it depends on the Java Project module and uses this style.</p>
36  *
37  * <p>This interface assumes following mapping pattern between source
38  * files and unit tests: <code>*.java -> *Test.java</code>. This mapping
39  * is used for example for unit test generation and for searching test for
40  * source. Usage of any other pattern will break this functionality.</p>
41  *
