Cucumber:Assert values irrespective of Index

I am working on updating functional test suites using Cucumber feature file.The issue my output is an array which is not sorted.Index of the object may change.
Array:
[{
"id": "12",
"name": "Something"
},
{
"id": "13",
"name": "Another Something"
}
]
Here I wanna assert name when Id=13 only.Any help would be appreciated.

The Json is list of objects within an Array so you need parse them and validate the each Object. You can do like below,
Code:
JSONArray jsonArray = new JSONArray(JsonAsString);
JSONObject jsonObject;
for (int i = 0; i < jsonArray.length(); i++) {
jsonObject = new JSONObject(jsonArray.get(i).toString());
if (jsonObject.get("id").toString().equalsIgnoreCase("13")) {
System.out.println("Name: " + jsonObject.get("name"));
//do your thing...
}
}
Output:
Name: Another Something

Need some assistance trying to parse this JSON response from our backend server

Currently working on an android app and I need help on how I can go about extracting the subfields within the responses field of this json object:
Currently I am doing the following to extract some of the other fields:
JSONObject json = new JSONObject(response2);
int id = json.getInt("id");
String desc = json.getString("description");
JSONObject json2 = json.getJSONObject("owner");
String username = json2.getString("userName");

You need to create logic to parse the data. Every item from the JSON string is in the JSONObject you created with
JSONObject json = new JSONObject(response2);
You're on the right track with what you're doing. Just use the corresponding methods available in JSONObject and JSONArray classes to move through the object.
Start with the main object
{ // <-- this is your main object (AKA JSONObject json = new JSONObject(response2))
"id": 1, // to pull this id use json.getInt("id");
"title": "some text here", // to pull this title use json.getString("title");
...
"owner": { // Here's the logic part, owner is itself, a JSON object. so now you must extract it and parse through it.
// to pull the "owner" JSON object, use JSONObject ownerObject = json.getJSONObject("owner");
"userId": 1, // Now use the ownerObject to pull it's values. ownerObject.getInt("userId");
"userName": "TestingUser", // to pull this userName use ownerObject.getString("userName");
...
}
...
}
If it's an array, for example:
"someJSONArray": [{ "id": 1, "userName": "TestingUser1" }, { "id": 2, "userName": "TestingUser2" }]
then you would call:
JSONArray someJSONArray = getJSONArray("someJSONArray");
// Get each object from the array.
JSONObject object1 = someJSONArray.getJSONObject(0);
JSONObject object2 = someJSONArray.getJSONObject(1);
or if the array contains a string, for example:
"someKey": [ 23, 435, 123, 6345, 123 ]
then you would call:
JSONArray someKeyArray = getJSONArray("someKey");
for (int i = 0; i < someKeyArray.length(); i++) {
// Extract the value.
int itemValue = someKeyArray.getInt(i);
}
The data is there, you just have to parse it.

How to get data from JSONobject and display it into a listview?

This is my JSON
{
"data": [
{
"id": 1,
"Name": "Choc Cake",
"Image": "1.jpg",
"Category": "Meal",
"Method": "",
"Ingredients": [
{
"name": "1 Cup Ice"
},
{
"name": "1 Bag Beans"
}
]
},
{
"id": 2,
"Name": "Ice Cake",
"Image": "dfdsfdsfsdfdfdsf.jpg",
"Category": "Meal",
"Method": "",
"Ingredients": [
{
"name": "1 Cup Ice"
}
]
}
]
}
Now I am trying to display it into a listView how would I do that this is what i have right now (for testing purposes i am just trying to display all the names in a toast)
JSONObject jsonObj = new JSONObject(jsonStr);
int length = jsonObj .length();
for(int i=0; i<length; i++) {
Toast.makeText(this, jsonObj.getJSONArray("data").
getJSONObject(i).getString("Name"), Toast.LENGTH_LONG).show();
}
The Above code only display one name and not multiple names. How can I make it for multiple names?

Take a look this code snippet
//getting whole json string
JSONObject jsonObj = new JSONObject(jsonStr);
//extracting data array from json string
JSONArray ja_data = jsonObj.getJSONArray("data");
int length = jsonObj .length();
//loop to get all json objects from data json array
for(int i=0; i<length; i++)
{
JSONObject jObj = ja_data.getJSONObject(i);
Toast.makeText(this, jObj.getString("Name").toString(), Toast.LENGTH_LONG).show();
// getting inner array Ingredients
JSONArray ja = jObj.getJSONArray("Ingredients");
int len = ja.length();
// getting json objects from Ingredients json array
for(int j=0; j<len; j++)
{
JSONObject json = ja.getJSONObject(j);
Toast.makeText(this, json.getString("name").toString(), Toast.LENGTH_LONG).show();
}
}
I recommend to use 'Log' instead using 'Toast'.
If any confusion or query let me know, i will try my best to resolve it.
If answer is satisfiable please mark it as correct answer.
Happy coding!
Thanks

You are getting the length of JSONObject, but you should get the length of JSONArray inside that JSONObject in order to iterate though json array items.
int length = jsonObj.getJSONArray("data").size()

I think you are guessing it wrong. Look closely you have a Json in that you have array which is JsonArray with the name/key "data"
then in that you can get it and traverse it index by index. For you I am providing you a road map so that things make easy for you conceptually
Make a model class which may able to store the values as you are getting in response of your api or in this json respone.
Take an array of type of your model class to store values
Now you can add for loop to save values or you can parse and save your jason array into your array you made to handle the jasonarray
this is easily be understand by this link and this is a working example to parse the json array and to show in your list view. You have nothing to worry about after reading these two links.

get your result from URL where your json is and store to any variable (result here) , then decode it i am showing below,
try this , it may give you some hint , i have not tried but may help you
JSONObject jsonObject = new JSONObject(result);
JSONArray jsonArray = jsonObject.optJSONArray("data");
if (jsonArray != null) {
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObjects = jsonArray.optJSONObject(i);
int id = jsonObjects.optInt("id");
String varMessage = jsonObjects.optString("varMessage");
String Image = jsonObjects.optString("Image");
String Category = jsonObjects.optString("Category");
String Method = jsonObjects.optString("Method");
JSONArray jsonArrayIngredients = jsonObject.optJSONArray("Ingredients");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObjects = jsonArray.optJSONObject(i);
String name = jsonObjects.optString("name");
}
}
}

Extracting data from JSON array

I know its an array, but I am completely new to JSON and need help comprehending how this is structured, here is my attempt at extracting data:
String JSonString = readURL("//my URL is here");
JSONArray s = JSONArray.fromObject(JSonString);
JSONObject Data =(JSONObject)(s.getJSONObject(0));
System.out.println(Data.get("name"));
My JSON data that I have goes like this :
{
"sports": [
{
"name": "basketball",
"id": 40,
"uid": "s:40",
"leagues": [
{
"name": "National Basketball Assoc.",
"abbreviation": "nba",
"id": 46,
"uid": "s:40~l:46",
"groupId": 7,
"shortName": "NBA",
"athletes": []
}
]
}
],
"resultsOffset": 10,
"resultsLimit": 10,
"resultsCount": 1,
"timestamp": "2013-11-18T03:15:43Z",
"status": "success"
}
I dont really have a strong grasp of this stuff so all the help is appreciated.

Here is the idea :
JSONObject root = new JSONObject(yourJsonString);
JSONArray sportsArray = root.getJSONArray("sports");
// now get the first element:
JSONObject firstSport = sportsArray.getJSONObject(0);
// and details of the first element
String name = firstSport.getString("name"); // basketball
int id = firstSport.getInt("id"); // 40
JSONArray leaguesArray = firstSport.getJSONArray("leagues");
// and so on, you can process leaguesArray similarly
It should work (feel free to complain about compile errors if there are any)

Your JSON data is an object (it starts with a curly brace). In the next inner layer, there is a single array (at key "sports"):
String jsonString = readURL("//my URL is here");
JSONObject result = JSONObject(jsonString);
JSONArray sports = result.getJSONArray("sports");
JSONObject sport = sport.getJSONObject(0);
System.out.println(sport.getString("name"));
I might have used another JSON library than you.

JSON means JavaScript Object Notation.
Objects in javascripts are just containers and can be represented by key-value pairs. Please find below notations to understand about json.
Represent objects in json: E.g. Student
{"name" : "Robin", "rollnumber" : "1"}
Represent array in json : E.g. Array of students
[{"name" : "Robin", "rollnumber" : "1"}, {"name" : "Mark", "rollnumber" : "2"}]
You can understand more on JSON from diagrams on this link http://www.json.org/fatfree.html
There are various ways available to to convert JSON to javaobject and javaobject to JSON : One of them is http://wiki.fasterxml.com/JacksonInFiveMinutes

Adding detailed code here along with the imports .
If this helps.
import org.json.JSONException;
import org.json.JSONObject;
public class extractingJSON {
public static void main(String[] args) throws JSONException {
// TODO Auto-generated method stub
String jsonStr = "{\"name\":\"SK\",\"arr\":{\"a\":\"1\",\"b\":\"2\"},\"arrArray\":[{\"a\":\"1\",\"b\":\"2\"}]}";
JSONObject jsonObj = new JSONObject(jsonStr);
String name = jsonObj.getString("name");
System.out.println(name);
String first = jsonObj.getJSONObject("arr").getString("a");
System.out.println(first);
first = jsonObj.getJSONArray("arrArray").getJSONObject(0).getString("a");
System.out.println(first);
}
}

Android - How to parse JSONObject and JSONArrays from api.rottentomatoes

so, there's this JSON code. Im trying to get the "abridged_cast".
but its complicated.
its JSONObject
inside JSONArray onside jSONObject Inside JsonArray....
{
"total": 591,
"movies": [
{
"title": "Jack and Jill",
"year": 2011,
"runtime": "",
"release_dates": {
"theater": "2011-11-11"
},
"ratings": {
"critics_score": -1,
"audience_score": 90
},
"synopsis": "",
"posters": {
"thumbnail": "",
"profile": "",
"detailed": "",
"original": ""
},
"abridged_cast": [
{
"name": "Al Pacino",
"characters": []
},
{
"name": "Adam Sandler",
"characters": []
},
{
"name": "Katie Holmes",
"characters": []
}
],
"links": {
"self": "",
"alternate": ""
}
}
],
"links": {
"self": "",
"next": ""
},
"link_template": ""
}
this is my code for getting "title" and "year"
if (response != null) {
try {
// convert the String response to a JSON object,
// because JSON is the response format Rotten Tomatoes uses
JSONObject jsonResponse = new JSONObject(response);
// fetch the array of movies in the response
JSONArray movies = jsonResponse.getJSONArray("movies");
// add each movie's title to an array
movieTitles = new String[movies.length()];
for (int i = 0; i < movies.length(); i++) {
JSONObject movie = movies.getJSONObject(i);
movieTitles[i] = movie.getString("title");
}
hope someone would help me because i cant figure out how to get the abridged_cast"

movies contains an array of "movie" objects. Each one of those objects contains a field abridged_cast that is an array of (let's call them "cast member") objects.
If you're not going to map to a POJO and instead are going through the JSON, you simply need to get that array in your loop after getting movie, and get each "cast member" object from that array in the same manner using another loop.
...
JSONArray cast = movie.getJSONArray("abridged_cast");
for (int j = 0; j < cast.length(); j++) {
JSONObject castMember = cast.getJSONObject(j);
...
}
Edit from comments: Your original question involved how to extract the information from the JSON you have; the above code explains that. It now seems like you're asking a more fundamental programming question around how to use it.
If you're going to use the included org.json classes that come with Android, you now know how to access the information in the returned JSON object. And you could write methods around the parsed JSONObject to access the data as-is using the objects and methods from the json.org package. For example, you could write a "getMovie()" method that took the name of the movie as a string and searched that "movies" array for the right one and returned it as a JSONObject.
Normally you would create classes in Java that encapsulate the data returned in that JSON and use data structures that lend themselves to your access patterns (For example, a Map that conatained all the movies using their names as keys). Using the org.json classes you'll have to instantiate those objects and populate them manually as you parse the JSON like you're doing in your question. If you used either the Gson or Jackson JSON parsing libraries they are capable of taking the JSON you have and mapping all the data to the classes your create and returning them in a single call.

try {
String Movie = null;
String abridged = null;
JSONArray jsonResponse = new JSONArray(response);
for (int i = 0; i< jsonResponse.length(); i++) {
Movie = jsonResponse.getJSONObject(i).getString("movies").toString();
System.out.println("movies="+Movie);
abridged = jsonResponse.getJSONObject(i).getString("abridged_cast").toString();
}
JSONArray jArray = new JSONArray(Movie);
for (int i = 0; i< jArray.length(); i++) {
String title = jArray.getJSONObject(i).getString("title").toString();
System.out.println("title="+title);
}
JSONArray jabridgeArray = new JSONArray(abridged);
for (int i = 0; i< jabridgeArray.length(); i++) {
String title = jabridgeArray.getJSONObject(i).getString("name").toString();
System.out.println("title="+title);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
