Good stuff.

There are a lot of unit tests for the C++ bindings (in
xapian-core/tests/ in the source tree), but for the bindings which use
SWIG to automate the wrapping we haven't generally tried to reproduce
the same level of detailed coverage because if SWIG successfully wraps
one method it's likely to also successfully wrap other methods which use
the same types.

Instead we have some tests that basic functionality works and we also
try to make sure that any custom SWIG typemaps have test coverage.  Then
we add regression tests for any bugs fixed.  This approach seems to
have worked out well.

There are Java bindings tests (xapian-bindings/java/SmokeTest.java) but
I'd probably suggest looking at a couple of other languages' tests so
you don't end up getting sidetracked by any Java-specific quirks.
