[jira] [Created] (BEAM-7142) Data Driven testing for BeamSQL

Rui Wang created BEAM-7142:
------------------------------

             Summary: Data Driven testing for BeamSQL
                 Key: BEAM-7142
                 URL: https://issues.apache.org/jira/browse/BEAM-7142
             Project: Beam
          Issue Type: New Feature
          Components: dsl-sql
            Reporter: Rui Wang


Current way to write BeamSQL test cases is too heavy: developers need to initialize pipeline, deal with PCollection, and use PAssert to verify pipeline results (sometime through INSERT INTO table and read data from table for assertion). 


Data driven testing, instead, should only ask developer to provide SQL query and a expected result in the form of List<Row> (simulate rows from result table). The test execution interface should just be a static function like "List<Row> run(String query)", and returned rows can be compared with expected result by checking equality.
