count members with jsonpath?

Question

Is it possible to count the number of members using JsonPath?

Using spring mvc test I\'m testing a controller that generates

{\"foo\": \"oof\", \"ba         


        

Answer 1

You can also use the methods inside the jsonpath, so instead of

mockMvc.perform(get(API_URL))
   .andExpect(jsonPath("$.*", hasSize(2)));

you can do

mockMvc.perform(get(API_URL))
   .andExpect(jsonPath("$.length()", is(2)));
