I am working with:
- Spring MVC Test
- Hamcrest
- JsonPath
I have the following how a response from the server:
MockHttpServletResponse:
Status = 200
Error message = null
Headers = {Content-Type=[application/json;charset=UTF-8]}
Content type = application/json;charset=UTF-8
Body = {
"id" : "100",
"nombre" : "Jesús Você",
"apellido" : "Mão Nuñez",
"fecha" : "1977-12-08"
}
Forwarded URL = null
Redirected URL = null
The following works as expected (is valid):
.andExpect(jsonPath("$").exists())
.andExpect(jsonPath("$", notNullValue()))
.andExpect(jsonPath("$", isA(LinkedHashMap.class)))
.andExpect(jsonPath("$.*").exists())
.andExpect(jsonPath("$.*", notNullValue()))
.andExpect(jsonPath("$.*", isA(JSONArray.class)))
.andExpect(jsonPath("$.*", hasSize(is(4))))
I need test that ("$")
is 1. Confirm exists 1 item. It to confirm again the following:
Body = {
"id" : "100",
"nombre" : "Jesús Você",
"apellido" : "Mão Nuñez",
"fecha" : "1977-12-08"
}
I've tried:
.andExpect(jsonPath("$", hasSize(is(1))))
Observe the difference between $
and $.*
, for the latter I know it counts the number of fields. But from the former I always get:
java.lang.AssertionError: JSON path "$"
Expected: a collection with size is <1>
but: was <{id=100, nombre=Jesús Você, apellido=Mão Nuñez, fecha=1977-12-08}>
at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:18
'Seems' the data is not a collection, but remember that .andExpect(jsonPath("$", isA(LinkedHashMap.class)))
pass. I am confused in someway.
Therefore is possible test that ("$")
is 1.? If yes, how?.
I've read count members with jsonpath?
And says:
To test size of array: jsonPath("$", hasSize(4))
To count members of object: jsonPath("$.*", hasSize(4))
My data returned is not an array, it is a LinkedHashMap.class
because if I use .andExpect(jsonPath("$").isArray())
I get:
java.lang.AssertionError: Expected an array at JSON path "$" but found: {id=100, nombre=Jesús Você, apellido=Mão Nuñez, fecha=1977-12-08}
Expected: an instance of java.util.List
but: <{id=100, nombre=Jesús Você, apellido=Mão Nuñez, fecha=1977-12-08}> is a java.util.LinkedHashMap
BTW: .andExpect(jsonPath("$.*").isArray())
pass.

exactly mean here? – Lyubomyr ShaydarivBody = { "id" : "100", "nombre" : "Jesús Você", "apellido" : "Mão Nuñez", "fecha" : "1977-12-08" }
is just one item with four fields. Therefore$.*
represents the item with four fields. But I need to test the item (I thought$
should be enough but fails). – Manuel JordanjsonPath("$").exists()
then? – Lyubomyr ShaydarivjsonPath("$").exists()
should pass too but It does not care if was 1 or 2 items. – Manuel Jordan
