JsonPath and XmlPath in Rest Assured

{
  "store": {
    "book": [
      {
        "category": "reference",
        "author": "Nigel Rees",
        "title": "Sayings of the Century",
        "price": 8.95
      },
      {
        "category": "fiction",
        "author": "Evelyn Waugh",
        "title": "Sword of Honour",
        "price": 12.99
      },
      {
        "category": "fiction",
        "author": "Herman Melville",
        "title": "Moby Dick",
        "isbn": "0-553-21311-3",

      },
      {
        "category": "fiction",
        "author": "J. R. R. Tolkien",
        "title": "The Lord of the Rings",
        "isbn": "0-395-19395-8",

      }
    ],
    "bicycle": {
      "color": "red",
      "price": 19.95
    }
  }
}

Lets find out below properties form above json –

1. the bicycle information – store.bicycle
2. First book in the list – store.book[0]
3. Author of the first book – store.book[0].author

package onlyfullstack.verifyResponse;

import io.restassured.path.json.JsonPath;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

public class JsonPathExample {

    String exampleJson;
    JsonPath jsonPath;

    @BeforeClass
    public void loadJsonFile() throws IOException {
        // Read the json from file and store in a String
        exampleJson = new String(Files.readAllBytes(Paths.get("src/test/resources/json-path-example.json")));
        // Create a JsonPath from the input String
        jsonPath = new JsonPath(exampleJson);
    }

    @Test
    public void jsonPathExamples() {
        System.out.println("Nested Value of store.bicycle - n" + jsonPath.get("store.bicycle"));
        System.out.println("nAccessing the Array Element - store.book[0]- n" + jsonPath.get("store.book[0]"));
        System.out.println("nAccessing the inner property of an array Element - store.book[0]- n" + jsonPath.get("store.book[0].author"));
    }
}

Output

Nested Value of store.bicycle -
{color=red, price=19.95}

What is XmlPath in Rest Assured?

Rest apis can also return the response in xml format. we can parse the XML and compare the objects but what if we want to compare only specific property or attribute of the XML?
XmlPath is used to get the value of any particular property or attribute form the XML.
Lets dive into the XmlPath and understand different scenarios to get the values for a specific property.

We have saved the below XML into xml-path-example.xml file –

<?xml version="1.0" encoding="UTF-8" ?>
<store>
    <book>
        <category>reference</category>
        <author>Nigel Rees</author>
        <title>Sayings of the Century</title>
        <price>8.95</price>
    </book>

        <price>22.99</price>
    </book>
    <bicycle>
        <color>red</color>
        <price>19.95</price>
    </bicycle>

3. Author of the first book – store.book[0].author

        System.out.println("nAccessing the inner property of an array Element - store.book[0]- n" + xmlPath.get("store.book[0].author"));
    }
}

Output

Lets go to our next tutorial where we will discuss below points :

Part 8 – Getting and Verifying Response in Rest Assured

Different ways to Verify the Response in Rest Assured
– 1. Verify the Response with JsonPath in Rest Assured
– 2. Extracting the response and Validating with assertion
– 3. Validating the response with Json String in Rest Assured
– 4. Validating the response from file in Rest Assured
– 5. Validating the response with Json Schema in Rest Assured
– What is Json Schema?
– How to generate the Json Schema?
