How to iterate through and access the JSON array elements using Rest Assured?
We can iterate through and access the JSON array elements using Rest Assured. First, we shall obtain a Response body which is in JSON format from a request. Then convert it to string.
To obtain JSON array size, we have to use the size method on the JSON array. Then introduce a loop that shall iterate up to the array size. We shall send a GET request via Postman on a mock API, and observe the Response.
Using Rest Assured, let us get the value of the Location field having the values State and zip. They are a part of the JSON array - Location.
Example
Code Implementation
import static io.restassured.RestAssured.given;
import org.testng.annotations.Test;
import io.restassured.RestAssured;
import io.restassured.path.json.JsonPath;
import io.restassured.response.Response;
public class NewTest {
@Test
public void jsonIterateArr() {
//base URI with Rest Assured class
RestAssured.baseURI = "https://run.mocky.io/v3";
//obtain Response from GET request
Response res = given()
.when()
.get("/8ec8f4f7-8e68-4f4b-ad18-4f0940d40bb7");
//convert JSON to string
JsonPath j = new JsonPath(res.asString());
//get values of JSON array after getting array size
int s = j.getInt("Location.size()");
for(int i = 0; i < s; i++) {
String state = j.getString("Location["+i+"].State");
String zip = j.getString("Location["+i+"].zip");
System.out.println(state);
System.out.println(zip);
}
}
}Output
