I am still learning the fundamentals of Calcite's API, and I've found that there are pre-made schemas and other utilities meant for testing inside of the Calcite repo.
Unfortunately it seems like a lot of these objects are private, because they aren't meant to be a part of the public API. I've taken to copy-pasting entire files to be able to get tests setup in my own project: - https://github.com/GavinRay97/GraphQLCalcite/blob/master/src/main/kotlin/HrClusteredSchemaKotlin.kt I think it could be valuable to others who aren't developing their code in the Calcite tree to be able to use the work that's been put into setting up premade test items. Or maybe there is a better way, would appreciate any advice. Thank you =) Gavin Ray
