test json of nested object

[Jon Anders Sollien]

My API returns this json object:

{

"Car": 

       [

{

"id": "2",

"Window": {

"id": "4"

}

}, 

{

"id": "7",

"Window": {

"id": "9"

}

}

]

}

, by using this method: 

expect().get(url)

It's okay to test if there exists a  "Car" with id=2:

expect()

.body("Car.id", hasItem(2) )

.get(url)

I can also test whetever there is a Window with id=4: 

expect()

.body("Car.Window.id", hasItem(4) )

.get(url)

But how can I test that it exists a Car with id=2 which contains a Window with id=4, without knowing the order of the Car-list?

Any help appreciated

Hi, 

Here you have to make use of Groovy GPath expressions, something like: 

expect().body("Car.find { it.id == '2' }.Window.id", equalTo("4")).when().get(url);

See this blog for some more info.

Works like a sharm. Many thanks

I have a little more complex example.

Is it possible to have multiple clauses in the find method? 

Lets say that in addition there is added a new car with id=2, with a Window with id=8. Let us assume that the Window object also contains the property "height" with value of "40" (cm). 

How can i assure that it exists a car with id=2 which contains a Window with id=8 and that THIS Window's height is 40?

Again thanks

Yes, something like this:

expect().body("Car.find { it.id == '2' }.Window.find { it.id == '8' }.height", equalTo(40)).when().get(url);

As I read, "find" returns only the first match. That means that if it is another car with the same id before this in the list, it will do the Window check on that one, and fail if the id or height is another. 

The only problem with that is that the car (id=2, Window{id=8, height=40})

You can use "findAll" if you want to return all that applies.
