Check output of JsonPath with Hamcrest Matchers

Question

I wrote Spring controller Junits. I used JsonPath to fetch all IDs from JSON using ["$..id"].

I have following as test method :

mockMvc.perform(get(baseURL + "/{Id}/info", ID).session(session))
    .andExpect(status().isOk()) // Success
    .andExpect(jsonPath("$..id").isArray()) // Success
    .andExpect(jsonPath("$..id", Matchers.arrayContainingInAnyOrder(ar))) // Failed
    .andExpect(jsonPath("$", Matchers.hasSize(ar.size()))); // Success

Following is the data that I passed :-

List<String> ar = new ArrayList<String>();
ar.add("ID1");
ar.add("ID2");
ar.add("ID3");
ar.add("ID4");
ar.add("ID5");

I got failure message as:-

Expected: [<[ID1,ID2,ID3,ID4,ID5]>] in any order
     but: was a net.minidev.json.JSONArray (<["ID1","ID2","ID3","ID4","ID5"]>)

Question is : How to handle JSONArray with org.hamcrest.Matchers; Is there any simple way to use jsonPath.

Settings :- hamcrest-all-1.3 jar , json-path-0.9.0.jar, spring-test-4.0.9.jar

Answer 1

JSONArray is not an array but rather an ArrayList (i.e., a java.util.List).

Thus you should not use Matchers.arrayContainingInAnyOrder(...) but rather Matchers.containsInAnyOrder(...).
