Maven: Use JUnit 5 with Spring Boot for unit and integration tests

A quick tip how to configure your Maven based Spring Boot application to use JUnit 5 for unit and integration tests
June 18, 2018 by Michael

Last weekend, a new version of the Apache Maven Surefire-Plugin has been released:

The Failsafe-Plugin has been updated as well. Both support JUnit 5 natively.

To make use of JUnit 5 in a Spring Boot 2 application, there’s not much todo. Here’s a gist of a POM that brings everything. See comments in the code. Basically all you have to do is overwrite the managed versions of the Surefire- and Failsafe-Plugins and then exclude the JUnit 4 dependency from Spring Boots Starter Test (and all other test related starters, i.e. security-starter-test). You’ll than declare both the JUnit 5 Jupiter Api and Engine, both in scope test. You could put the engine into the plugins dependency, but I couldn’t think of an aspect that’s improved by more cruft. Then, write unit and integration tests as shown (the later with annotated with @ExtendWith(SpringExtension.class)).

You’ll notice that only the Failsafe-Plugin has been declared. Spring Boots parent POM already takes care of the Surefire-Plugin.

And that’s all you need for Spring Boot 2 with JUnit 5.
