This tutorial will guide you on how to incorporate JUnit support into your Spring Boot application based on Maven.
Spring Boot Starter Test Dependency
To add JUnit and Mockito support to your Maven-based Spring Boot application, include the following dependencies in the <dependencies> section of your pom.xml file:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
By adding the spring-boot-starter-test dependency to your project, you’ll get access to a number of useful testing libraries, including JUnit Vintage for backwards compatibility with JUnit 3 and 4, Mockito for mocking objects, and Hamcrest for more expressive assertions. Here’s the complete list of compile dependencies you’ll get with this dependency:
- JUnit Jupiter
- Mockito
- Mockito-core
- Mockito JUnit Jupiter support
- json-path
- jackarta.xml.bind-api
- assertj-core
- hamcrest
- jsonassert
- spring-core
- spring-test
- xmlunit-core
- spring-boot-starter
- spring-boot-test
- spring-boot-test-autoconfigure
Once you’ve added the spring-boot-starter-test dependency to your application’s pom.xml file, you’ll be ready to start writing your unit tests.
Spring Security Test
If you have Spring Security enabled in your Spring Boot application, there is one additional dependency that you’ll need to include. The dependency you need is:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-test</artifactId>
<scope>test</scope>
</dependency>
This dependency provides testing utilities for Spring Security, allowing you to write integration tests for your security configuration. Make sure to include this dependency in the <dependencies> section of your application’s pom.xml file if you plan on testing your Spring Security setup.
Conclusion
In conclusion, JUnit plays a crucial role in testing Spring Boot applications, enabling developers to ensure the reliability and correctness of their code. By incorporating JUnit into the testing process, Spring Boot developers can benefit from comprehensive and efficient testing capabilities.
