1.1 Code Snippet for API testing

Here i am just conferring how to parse and How to convert JsonObject to Java Object.So that you could use it your live projects using selenium.

Application contentType : Json

Objective : To validate Address : Chicago, IL, USA.

GoogleMaps API : http://maps.googleapis.com/maps/api/geocode/json?address=chicago&sensor=false

We can easily parse Json using “json-lib-2.4-jdk15.jar” Download from here…!

Please consider the below code as a reference snippet:

package code;

import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Scanner;

import org.json.JSONArray;
import org.json.JSONObject;
import org.testng.Reporter;
import org.testng.annotations.Test;

public class ReadJsonObject {

    @Test
    public void aptTesting() throws Exception {
    try {
        URL url = new URL(“http://maps.googleapis.com/maps/api/geocode/json?address=chicago&sensor=false&#;);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod(“GET”);
        conn.setRequestProperty(“Accept”, “application/json”);

        if (conn.getResponseCode() != ) {
            throw new RuntimeException(” HTTP error code : ”+ conn.getResponseCode());
        }
        Scanner scan = new Scanner(url.openStream());
        String entireResponse = new String();
        while (scan.hasNext())
        entireResponse += scan.nextLine();
        System.out.println(“Response : “+entireResponse);
        scan.close();

        JSONObject obj = new JSONObject(entireResponse );
        String responseCode = obj.getString(“status”);
        System.out.println(“status : ” + responseCode);

        JSONArray arr = obj.getJSONArray(“results”);
        for (int i = 0; i < arr.length(); i++) {
            String placeid = arr.getJSONObject(i).getString(“place_id”);
            System.out.println(“Place id : ” + placeid);
            String formatAddress = arr.getJSONObject(i).getString(“formatted_address”);
            System.out.println(“Address : ” + formatAddress);

            //validating Address as per the requirement
            if(formatAddress.equalsIgnoreCase(“Chicago, IL, USA”))
            {
                System.out.println(“Address is as Expected”);
            }
            else
            {
                System.out.println(“Address is not as Expected”);
            }
        }
        conn.disconnect();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

That’s it, now you know how to convert JsonObject to Java Object and use it in your Selenium snippet.
