-----------------------------------
Assignee: (was: Paul Rogers)
> Convert Analyzer AST to JSON for test verification
> --------------------------------------------------
>
> Key: IMPALA-7968
> URL: https://issues.apache.org/jira/browse/IMPALA-7968
> Project: IMPALA
> Issue Type: Improvement
> Components: Frontend
> Affects Versions: Impala 3.1.0
> Reporter: Paul Rogers
> Priority: Minor
>
> The FE code provides the {{PlannerTest}} which parses a SQL statement,
> analyzes it, plans the query, and writes selected portions of the plan to a
> file to be compared with a "golden" copy. Very helpful.
> At present, the Analyzer itself has no such test framework. This ticket asks
> to provide one. Key pieces:
> * JSON serializer to write the AST to JSON in a compact format for testing.
> * Potentially a YAML form of the above if the JSON grows too bulky
> * Serialization code in the AST objects to produce the JSON
> * Additions to the PlannerTest framework to add an AST section and an AST
> test framework
> * The actual AST tests
