BEFORE YOU START

JSONPath is concise, but a wildcard or recursive selector can match more data than expected. Test against both normal and edge-case payloads.

01

Start at the root

Confirm the top-level shape before adding nested properties.

EXAMPLE
$
02

Add one segment at a time

Move from a collection to an index or wildcard while checking the number of results.

EXAMPLE
$.store.books[*].title
03

Test missing and empty fields

Automation should define what happens when a property is absent, null, or an array is empty.

EXAMPLE
$.store.books[0]
04

Confirm implementation compatibility

Complex filters historically differ between libraries, so run the final query with the production implementation.

EXAMPLE
[?(@.price < 40)]
Key takeaways
  • Inspect matched paths, not only values.
  • Wildcards and recursion can broaden a query unexpectedly.
  • Verify complex filters in the production library.
