In the last tutorial, I explained How to test POST request from JSON Object in Rest Assured where the request body is built in JSONObject. In this tutorial, I will create a request body using JSON Object in Rest Assured.
We can create a JSON Object using a Map in Java. A JSON Object is a key-value pair and can be easily created using a Java Map. A Map in Java also represents a collection of key-value pairs.
To create a request body using JSON Object using HashMap, we need to add a Maven dependency.
<dependencies>
<dependency>
<groupId>org.json</groupId>
<artifactId>json</artifactId>
<version>20231013</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.13.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.rest-assured</groupId>
<artifactId>rest-assured</artifactId>
<version>5.3.2</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.15.2</version>
</dependency>
</dependencies>
I have created a simple Java map and filled it with the values that represent JSON properties.
import io.restassured.RestAssured;
import io.restassured.http.ContentType;
import org.junit.Test;
import java.util.HashMap;
import java.util.Map;
import static org.hamcrest.Matchers.equalTo;
public class Json_Demo {
@Test
public void passBodyAsMap() {
Map<String, String> map = new HashMap<String, String>();
map.put("employee_name", "MapTest");
map.put("employee_salary", "99999");
map.put("employee_age", "30");
map.put("profile_image", "test.png");
RestAssured.given()
.contentType(ContentType.JSON)
.body(map)
.log().all()
.when()
.post("https://dummy.restapiexample.com/api/v1/create")
.then()
.assertThat().statusCode(200)
.body("data.employee_name", equalTo("MapTest"))
.body("data.employee_age", equalTo("30"))
.body("data.employee_salary", equalTo("99999"))
.body("message", equalTo("Successfully! Record has been added.")).log().all();
}
}
The request body as well as the response body will look as shown below:-
Above one is a simple JSON Request Body. Let us take an example of a Complex Request Body or nested Request Body as shown below.
Let us create a Java program to understand this:
import io.restassured.RestAssured;
import io.restassured.http.ContentType;
import org.junit.Test;
import java.util.HashMap;
import java.util.Map;
import static org.hamcrest.Matchers.equalTo;
public class Json_Demo {
@Test
public void passBodyAsMultipleMap() {
// First JSON Object using Hash Map
Map<String, Object> data = new HashMap<String, Object>();
data.put("employee_name", "MapTest");
data.put("profile_image", "test.png");
// Second JSON Object using Hash Map
Map<String, String> msg = new HashMap<String, String>();
msg.put("updated_message", "Details of New Resource");
msg.put("employee_age", "30");
data.put("details", msg);
data.put("employee_salary", "99999");
RestAssured.given().contentType(ContentType.JSON).body(data).log().all()
// WHEN
.when().post("https://dummy.restapiexample.com/api/v1/create")
// THEN
.then().assertThat().statusCode(200).body("data.employee_name", equalTo("MapTest"))
.body("data.details.updated_message", equalTo("Details of New Resource"))
.body("data.details.employee_age", equalTo("30")).body("data.employee_salary", equalTo("99999"))
.body("message", equalTo("Successfully! Record has been added.")).log().all();
}
}
The request body as well as the response body will look as shown below image. The first part is the body of the request and the second part is the response provided by the API.
Congratulations on making it through this tutorial and hope you found it useful! Happy Learning!!
