Combining multiple tests in validating JSON content with jq

I have following JSON object

{"color": "red", "shapes": [ "square", "triangle" ]}

I would like to validate the JSON object using jq using following conditions:

The returned result should be either true or false.

I have 2 jq command which validate both conditions, but I'm not sure how to combine this into 1 expression:

json='{"color": "red", "shapes": [ "square", "triangle" ]}'
echo "$json" | jq '.["color"] | test("red")'
echo "$json" | jq 'any(.shapes[]; contains("round"))|not'

Any pointers or help would be appreciated.

A correct way to test a collection of conditions is using and.

In your case, a correct test would be:

(.color == "red") and (.shapes|index("round") == null)

Example (typescript):

jq '(.color == "red") and (.shapes|index("round") == null)'
{"color": "red", "shapes": [ "square", "triangle" ]}
true

In jq, not is a syntactically ordinary filter, so you could write the second condition as: (.shapes | index("round") | not).

You can simply verify that both tests return true with all:

echo '{"color": "red", "shapes": [ "square", "triangle" ]}' |
  jq '[(.["color"] | test("red")),
       (any(.shapes[]; contains("round"))|not)
      ] | all'

Create an array containing the results of each test, then pipe that array to all.
