Review Comment:
I prefer using boolean flags over `Mockito.verify` for this test because:
1. More realistic: The spy approach requires exposing and wrapping the
session catalog instance in `newSessionCatalog()`, which isn't how users would
actually extend these classes.
* We need to create a CustomSessionCatalog in advance, wrap it with
spy, and return it in `newSessionCatalog`.
3. Test the right thing: The boolean verifies that our custom implementation
runs. `newTableOps()` will be called either way (can't differentiate whether
the default or custom is invoked or not), so `verify()` doesn't actually prove
customization worked.
4. Simpler and straight forward: set a flag in the override to prove the
custom code path is executed. No mocking scaffolding needed.
