How to find the length or size of the elements of response array in rest assured-CodePudding

I am new to rest assured. I have tried below code for getting response

RestAssured.baseURI = "http://localhost:8090/api";
Response resp = 
          given().
          when().get("/modules")
         .then().extract().response();

This is JSON response

    [
        {
            "moduleid": "1000",
            "module": "reader",
            "title": "Learn to read",
            "description": "Learn to read and understand code"
        },
       {
        "moduleid": "1005",
        "module": "debug",
        "title": "Can you fix it?",
        "description": "Learn how to uncover logical mistakes"
       },
    ]

How do I get the length or size of the elements of that array.

CodePudding user response：

Since the response document does not tell you the amount of elements (and we are not sure whether the server returns a correct content-size header, you will have to parse the response and count.

You can do something like this:

public static void main(String[] args) {

    RestAssured.baseURI = "http://demo1954881.mockable.io";
    Response resp =
            given().
                    when().get("/modules")
                    .then().extract().response();

    ArrayList<Map> parsed = resp.jsonPath().get();
    List<Map> result = parsed
            .stream()
            .filter(i -> "1000".equals(i.get("moduleid")))
                    .collect(Collectors.toList());

    result.forEach(
            map -> System
                    .out
                    .printf(
                       "Item with [moduleid=%s] has size of %d\n",
                       map.get("moduleid"), map.size())
    );
}

Since you are ware of the response structure it is a simple array of maps. So you serialize it into array of maps and then use regular toolset for manipulating with data.
