Thank you. The patch applied fine, with no errors.

Is this the type of testing that would be helpful? I plan to construct a 
number of separate queries to test more nuanced edge cases. This test 
simply compares the output of 4 separate sub-queries that should provide 
the same results.

SELECT
   CASE WHEN jop = jp_expr AND jop = jval AND jop = jval_path
     THEN 'pass'
     ELSE 'fail'
   END
FROM
   (
     -- jsonb operator
     SELECT count(*)
     FROM testjsonb
     WHERE j->>'abstract' LIKE 'A%'
   ) as jop,
   (
     -- jsonpath expression
     SELECT count(*)
     FROM testjsonb
     WHERE j @? '$.abstract ? (@ starts with "A")'
   ) as jp_expr,
   (
     -- json_value()
     SELECT count(*)
     FROM testjsonb
     WHERE JSON_VAlUE(j, 'lax $.abstract') LIKE 'A%'
   ) as jval,
   (
     -- json_value(jsonpath)
     SELECT count(*)
     FROM testjsonb
     WHERE JSON_VALUE(j, 'lax $.abstract ? (@ starts with "A")') IS NOT NULL
   ) as jval_path;


If I'm completely off base for how testing is normally conducted, please 
let me know.

Thanks,
