Robert Metzger commented on FLINK-21347:
----------------------------------------
I'm not sure if having an interface really makes things much simpler. The
interface would have ~35 methods + ~15 methods in AccessExecutionGraph. That
doesn't necessarily sound like a simple interface for testing.
We need to carefully review which methods to expose.
> Extract interface out of ExecutionGraph for better testability

> The ExecutionGraph class is currently not very handy for tests, as it has a
> lot of dependencies. Extracting an interface for the ExecutionGraph will make
> testing and future changes easier.
