Negate the hasItem assertion

assertThat(someCollection, not(hasItem(someItem)))

If you need to Assert an Array, the same logic use not(hasItemInArray())

final String[] availableIds = {"123", "321"};
final String userId = "333";


softAssert.assertThat("Id not found", availableIds, not(hasItemInArray(userId)));
softAssert.assertAll();

or you can do;

.extract().jsonPath().getObject("data", pojo.class);
(above is response)


assertThat(response, not(hasItem(bodyYouArePosting)));
