twalthr opened a new pull request, #23584:
URL: https://github.com/apache/flink/pull/23584
## What is the purpose of the change
This adds infrastructure for declaring table test programs once and use them
for various purposes.
```
/**
* A generic declaration of a table program for testing.
*
* <p>A test program only defines the basic test pipeline (from source to
sink) and required
* artifacts such as table sources and sinks, configuration options, and
user-defined functions.
*
* <p>Tests programs are intended to reduce code duplication and test the
same SQL statement though
* different layers of the stack. Different {@link TableTestProgramRunner}s
can share the same
* program and enrich it with custom implementation and assertions.
*
* <p>For example, a SQL query such as {@code SELECT * FROM (VALUES (1),
(2), (3))} can be declared
* once and can be shared among different tests for integration testing,
optimizer plan testing,
* compiled plan testing, transformation testing, and others.
