Are you looking for this? It iterates over the array .[], selects those item objects whose .test field evaluates to true (implicit), and traverses further down to the .name field. Using the --raw-output (or -r) option renders the output raw text (instead of JSON string in this case).

jq -r '.[] | select(.test).name' ddd

BB
