The JSON string form of `Catalog` is stable. It will not change from one execution to another. I'd prefer to assert the exact string JSON representation in a test method dedicated to this case and leave this assertion out of the "round trip" tests. ########## api/management-model/src/test/java/org/apache/polaris/core/admin/model/CatalogSerializationTest.java: ########## @@ -0,0 +1,132 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.

Please consider producing individual `Catalog` objects as test method arguments (and remove `TestCase`). If you prefer to have hand-written test case descriptions, please consider using `ArgumentSet` (from JUnit5). -- This is an automated message from the Apache Git Service.
