Validating an array within a collection

[zerbol...@gmail.com]

Hello,

I have an array within a collection I'd like to validate. The problem is I can't seem to match the array using hasItems and the array itself. It seems that it is as expected two arrays, but the matcher appears to think they're different I'm not quite sure why. Can anybody help?

Here is the code:

given().get(url).

then().

body(matchesJsonSchemaInClasspath("Schema.json"))

.and()

.body("id", hasItems("id1234","id5678"))

.and()

.body("name", hasItems("Aname", "AnotherName"))

.and()

.body("categories", hasItems("Item->FirstItem, Item->SecondItem,Item->ThirdItem, Item->FourthItem, Item->FifthItem, Item->SixthItem", "Item->FirstItem"))

.log().body();

I get the following error:

JSON path categories doesn't match.

Expected: (a collection containing 

"Item->FirstItem, Item->SecondItem,Item->ThirdItem, Item->FourthItem, Item->FifthItem, Item->SixthItem", "Item->FirstItem")

  Actual:      [[Item->FirstItem, Item->SecondItem,Item->ThirdItem, Item->FourthItem, Item->FifthItem, Item->SixthItem], [Item->FirstItem]]

And here is the json:

[

  {

    "id": "id1234",

    "name": "Aname",

    "things": [

      "Item->FirstItem",

      "Item->SecondItem",

      "Item->ThirdItem",

      "Item->FourthItem",

      "Item->FifthItem",

      "Item->SixthItem"

    ],

    "site": "www.asite.com",

    "rating": "999",

    "date": "13/12/2015",

    "year": 2015,

    "length": 120,

    "description": {

      "short": "blah.",

      "medium": "blah blah blah",

      "long": "blah blah blah blah blah."

    },

    "passed": true,

    "created": {

      "user": "jimmy",

      "time": "2015-06-22T19:33:56.411Z"

    },

    "updated": {

      "user": "jeff",

      "time": "2015-06-22T19:33:56.411Z"

    }

  },

  {

    "id": "id5678",

    "name": "AnotherName",

    "categories": [

      "Item -> FirstItem"

    ],

    "website": "www.anothersite.com",

    "summary": {

      "short": "blah.",

      "medium": "blah blah."

    },

    "created": {

      "user": "steff",

      "time": "2015-06-22T19:33:56.411Z"

    },

    "updated": {

      "user": "james",

      "time": "2012-04-24T18:25:43.511Z"

    }

  }

]

Thanks,

Hi, 

I think I know what's going on. The path "categories" is located in json objects that is located inside a list o what happens when you do body("categories") is that GPath will return a list of the the matching values. The simplify things image that you have this object instead:

[

 {

    "id": "id5678",

    "name": "AnotherName",

    "categories": "my category"

 }

... 

]

What happens when you do body("categories") is that a list containing the value of "categories" is returned, i.e. ["my category"]. Now back to your example:

[

 {

    "id": "id5678",

    "name": "AnotherName",

    "categories":  [

      "Item -> FirstItem"

    ],

 }

... 

]

Just as before body("categories") returns the value of "categories" that now happens to be a list containing ["Item -> FirstItem"], so that's returned by body("categories") is now a list containing a list containing one element "Item -> FirstItem", i.e. [["Item -> FirstItem"]]. This is why you cannot use the hasItems Hamcrest matcher since it expects a list and not a list of lists. What I usually do in these cases is to flatten the lists before I compare it to the Hamcrest matcher. For example:

.body("categories.flatten()", hasItems("Item->FirstItem, Item->SecondItem,Item->ThirdItem, Item->FourthItem, Item->FifthItem, Item->SixthItem", "Item->FirstItem"))

That ought to do it!

Regards,

/Johan

Sorry for all the typos, I was a bit too fast.. Hope it makes sense anyways.

Hi Johan,

Thanks for the response. When I use the above code it seems to just flatten the two lists into one , but the matcher still fails as it expects two collections. 

java.lang.AssertionError: 1 expectation failed.

JSON path categories.flatten() doesn't match.

Expected: (a collection containing "Item->item1, Item->item2, Item->item3, Item->item4, Item->item5, Item->item6" and a collection containing "Item -> item1")

  Actual: ["Item->item1, "Item->item2, "Item->item3, "Item->item4, "Item->item5, "Item->item6, "Item -> item1]

Thanks,

Sorry that error should be:

java.lang.AssertionError: 1 expectation failed.

JSON path categories.flatten() doesn't match.

Expected: (a collection containing "Item->item1, Item->item2, Item->item3, Item->item4, Item->item5, Item->item6" and a collection containing "Item -> item1")

  Actual: [Item->item1, Item->item2, Item->item3, Item->item4, Item->item5, Item->item6, Item -> item1]

You're probably doing something like:

.. .body("categories.flatten()", hasItems("Item->item1, Item->item2, Item->item3, Item->item4, Item->item5, Item->item6");

which is not correct. You need to put a " around each element like this:

.. .body("categories.flatten()", hasItems("Item->item1", "Item->item2", "Item->item3", "Item->item4", "Item->item5", "Item->item6");

HI Johan,

Sorry a bit new to the rest assured and hamcrest. You're right, that's working now thanks.
