Music to my ears, @kennknowles!
Take a glance at
https://github.com/apache/calcite-avatica/blob/master/server/src/test/java/org/apache/calcite/avatica/remote/RemoteMetaTest.java,
or maybe
https://github.com/apache/calcite-avatica/blob/master/server/src/test/java/org/apache/calcite/avatica/remote/ArrayTypeTest.java.
Essentially, we have higher-level, end-to-end tests in the avatica-server
module, but not any clear separation about where the tests should go in there :)
Let me know if that's not enough of a pointer to get you going (PS: I still
haven't checked to make sure HSQLDB supports structs enough to do what you want
-- in case you run into issues).
