In the previous tutorial, I explained about Integration Testing of SpringBoot Application with Serenity BDD, Cucumber and JUnit4. In this tutorial, I will explain the Testing of the SpringBoot Application with Serenity and JUnit5.
This framework consists of
- SpringBoot Starter Parent – 3.1.0
- Serenity – 3.6.12
- Serenity JUnit5 – 3.6.12
- Serenity Rest Assured – 3.6.12
- Serenity Spring – 3.6.12
- JUnit Platform – 1.9.2
- Java 17
- Maven – 3.8.6
What is SpringBoot Application?
Spring Boot is an open-source micro-framework that provides Java developers with a platform to get started with an auto-configurable production-grade Spring application.
- Comes with embedded HTTP servers like Tomcat or Jetty to test web applications.
- Adds many plugins that developers can use to work with embedded and in-memory databases easily. Spring allows you to easily connect with database and queue services like Oracle, PostgreSQL, MySQL, MongoDB, Redis, Solr, ElasticSearch, Rabbit MQ, and others.
Project Directory Structure
What is RestController?
HTTP requests are handled by a controller in Spring’s approach to building RESTful web services. The @RestController annotation identifies these components, and the GreetingController shown below (from src/main/java/com/example/springboot_demo/HelloController.java) handles GET requests for / and /qaautomation by returning a new instance of the Greeting class. Spring RestController takes care of mapping request data to the request-defined handles method.
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
@GetMapping(path="/")
String hello() {
return "Hello World, Spring Boot!";
}
@GetMapping(path="/qaautomation")
String qaautomation() {
return "Hello QA Automation!";
}
}
Implementation Steps
- Create a source folder – src/test/resources to create properties file
- Add SpringBootTest, Serenity and JUnit5 dependencies to the project
- Create the Test and Helper classes.
- Create an application.properties file in src/test/resources
- Create serenity.properties at the root of the project
- Run the tests from JUnit5
- Run the tests from Command Line
- Serenity Report Generation
Step 1 – Create a source folder – src/test/resources to create test scenarios in the Feature file
Right-click on the test directory and select New->Directory and select resources (Maven Source Directories).
Step 2 – Add SpringBootTest, Serenity, and JUnit5 dependencies to the project
We have added SpringBootTest, Serenity, Rest Assured, and JUnit5 dependencies to pom.xml.

Step 3 – Create the Test classes
- uses @SpringBootTest annotation which loads the actual application context.
- uses WebEnvironment.RANDOM_PORT to create and run the application at some random server port.
- @LocalServerPort gets the reference of the port where the server has started. It helps in building the actual request URIs to mimic real client interactions.
Below is the code of the StepDefinition and Helper class. These classes are created in the src/test/java directory.
AbstractRestAssuredHelper
import io.restassured.RestAssured;
import io.restassured.specification.RequestSpecification;
import net.serenitybdd.rest.SerenityRest;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.web.server.LocalServerPort;
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public abstract class AbstractRestAssuredHelper {
private final static String BASE_URI = "http://localhost";
@LocalServerPort
private int port;
@Value("${server.servlet.context-path}")
private String basePath;
protected void configureRestAssured() {
RestAssured.baseURI = BASE_URI;
RestAssured.port = port;
RestAssured.basePath = basePath;
}
protected RequestSpecification getAnonymousRequest() {
configureRestAssured();
return SerenityRest.given();
}
}
This class sends the request and receives a response after performing the GET operation. Here, the validation of the response also takes place by asserting the expected and actual response
import io.restassured.response.ValidatableResponse;
import net.serenitybdd.junit5.SerenityJUnit5Extension;
import net.thucydides.core.annotations.Steps;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
@ExtendWith(SerenityJUnit5Extension.class)
class SpringbootDemoApplicationTests {
@Steps
AbstractRestAssuredHelper helper;
private ValidatableResponse response;
@Test
public void verifyController1() {
response = helper.getAnonymousRequest()
.header("Content-Type", "application/json")
.when().get("/").then().statusCode(200);
String Actual = response.extract().asString();
System.out.println("Result :"+Actual);
Assertions.assertEquals("Hello World, Spring Boot!", Actual);
}
@Test
public void verifyController2() {
response = helper.getAnonymousRequest()
.header("Content-Type", "application/json")
.when().get("/qaautomation").then().statusCode(200);
String Actual = response.extract().asString();
System.out.println("Result :"+Actual);
Assertions.assertEquals("Hello QA Automation!", Actual);
}
}
Step 4 – Create an application.properties file in src/test/resources
Application.properties is created under src/test/resources for the test profile. If you want to run the SpringBootApplication from DEV profile, then create application.properties file in src/main/resources.
spring.profiles.active=test
server.port=8090
server.servlet.context-path=/demo
spring.profiles.active – property to specify which profiles are active. The default profile is always active.
server.port – By default, the embedded server starts on port 8080. Now the server will start on port 8090
server.servlet.context-path – the context path in Spring Boot can be changed by setting a property, server.servlet.context-path.
Step 5 – Create serenity.properties at the root of the project
serenity.project.name = Testing of SpringBoot Application with Serenity and JUnit5 Demo
Step 6 – Run the tests from JUnit5
Right-click on the Test class and select Run ‘SpringBootDemoApplicationTests’.
The output of the above program is
This image shows that the profile name is “test”. Application is started on port – “58458” and the context path is “/demo”.
Step 7 – Run the tests from Command Line
Run the tests from the command line by using the below command
mvn clean verify
The output of the above program is
Step 8 – Serenity Report Generation
The serenity test reports are generated under target/site/serenity.
Below is the sample Index.html Report.
Go to Test Results, present at the top left of the index.html page.
