Rest Assured Empty response body structure

Question

I'd like to test a find rest service, if I find smth I want to delete from the database, otherwise do nothing

I use it like this (where rs is the Response from find)

 JsonPath jsonPath = rs.getBody().jsonPath();
 Object foundName= jsonPath.get("name");

  if (foundName!= null) {

   expect().statusCode(200).when().delete("..." + foundName);

 }

So when nothing is found how to check the foundName for it , because I tried foundName!=null or foundName != "", and still it's not working. So please explain what is the structure of an empty response body

In java you cannot compare strings with `!=`. Use the `String.equals("")` method — Tim, Apr 02 '14 at 10:46
I tried debugging and foundName has value ArrayList with subelements : elementData = Object[0] (displayed value is []) , modCount = 0 , size = 0 — April, Apr 02 '14 at 11:34
So obviously it's not a string as you expected. Now you're a step closer to finding the error do you think you can work from here? — Tim, Apr 02 '14 at 11:37
Well, I still don't know how to correctly check foundName, so I would appreciate any suggestions — April, Apr 02 '14 at 11:39

Based on the debug info foundName is of type List , so the solution was to cast foundName to List and check if it's empty.

 List foundName = (List)jsonPath.get("name");
 foundName.isEmpty()

rs.body(blankOrNullString());

worked for me to verify the response body is null or blank.

You could call jsonPath.getString("name") which casts your (empty) response body to String and you could check it with equals("") (see RESTassured JavaDoc). I assumed that "name" is of type String.

I tried that it like that as well, but jsonPath.getString() basicaly uses the same jsonPath.get() internally, so it's the same thing I tried with get() – April Apr 02 '14 at 12:08
I see. So what does the returned string contain? – lightwalker Apr 03 '14 at 07:34
