Practice: Spring Boots Test, Devtools, Actutor

Part 1: Unit testing in JUnit 5 and Mockito

1.1. Project Structure: Reuse old Rest API project (JPA + OracleDB)

1.2. Write test cases for each layer

• Sample Oracle database used during testing

---

• Test Folder Structure

---

1.2.1. CRUD methods for the Repository layer

• Setup class TutorialRepositoryTest

  * @Mock: virtual object, which simulates the behavior and properties of the real object
  

• GET: find by published

• CREATE/UPDATE: save Tutorial

• DELETE: delete all Tutorials

• Result: Pass all test cases

1.2.2. Write test cases for Service layer methods

• Setup class TutorialServiceImplTest

• Find all Tutorials

• Save Tutorial

• Delete all Tutorials

• Result: Pass all test cases

1.2.2. Write test cases for API of Controller layer

• Setup class TutorialControllerTest

• API: GET /api/tutorials

• API: GET /api/tutorials/{id}

• API: GET /api/tutorials/published

• API: POST /api/tutorials

• API: PUT /api/tutorials/{id}

• API: DELETE /api/tutorials/{id}

• API: DELETE /api/tutorials/

• Result: Pass all test cases

Part 2: Setting Actuator and DevTools

2.1. Spring Boot Actuator

Dependence

<dependency>
  	<groupId>org.springframework.boot</groupId>
  	<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

The corresponding configuration in the file application.properties

• Set up port 8090 for monitoring management
• Set enable for all endpoints
• Shut down the application using Actuator

Result

• Run-time port 8090

• Actuator Endpoints

• Actuator Health

• Actuator ShutDown

  • Postman request API: POST /actuator/shutdown

  • Console

2.2. DevTools

• Dependence

  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
    <scope>runtime</scope>
    <optional>true</optional>
  </dependency>
  

• Settings when using IntelliJ

• The program is running on port 8090

  

• Set up port 8091 for monitoring management

• Endpoints after changing port 8091

  • Port 8090:
  • Port 8091:
