Access elements of an anonymous array via JsonPath in RestAssured

Question

I have an anonymous array in JSON returned from a service like:

[
  {"foo":1, "bar":2 , "baz":3 },
  {"foo":3, "bar":4 , "baz":5 }
]

How can I access the bar elements e.g. in

expect().body("$[*].bar", hasItems(2,4)) 

I tried a few possibilities that I found here and also on the JsonPath page by Stefan Gössner, but whatever I try I get exceptions. My issue seems to directly come from trying to access that list of items.

Answer 1

Given that you have:

[
  {"foo":1, "bar":2 , "baz":3 },
  {"foo":3, "bar":4 , "baz":5 }
]

You can do the following in Rest Assured:

then().body("bar",hasItems(2,4)) 

or

expect().body("bar",hasItems(2,4)) 

if you're using the legacy API.

I know it is not valid - that is why I wrote "pseudocode" in the first line of my question :-) – Lizzielizzy

Answer 2

Johan's answer is correct, just for the sake of completeness: An alternative way to check the 'bar' elements with rest-assured would be

expect().
    body("[0].bar", equalTo(2)).
    body("[1].bar", equalTo(4));

Just be careful with this - the order of elements may not always be the same. – Housecoat

That's right, that's the main reason for using "hasItems" in the first place - you use it in cases where you can't expect a specific (and fixed) order. – Madea

This is correct but if order gets change, it will surely fail. – Bluegrass

maybe Hamcrest containsInAnyOrder() will help you... hamcrest.org/JavaHamcrest/javadoc/1.3/org/hamcrest/… – Topazolite
