How do I run JUnit 5 integration tests with the Maven Failsafe plugin?

Question

The Maven Failsafe plugin won't find my JUnit 5 integration tests when I'm running the command mvn clean failsafe:integration-test, although it can find the files.

I have the junit-jupiter-api and junit-jupiter-engine as test dependencies:

<properties>
    <junit.jupiter.version>5.0.1</junit.jupiter.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-api</artifactId>
        <version>${junit.jupiter.version}</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-engine</artifactId>
        <version>${junit.jupiter.version}</version>
        <scope>test</scope>
    </dependency>
</dependencies>

My integration tests are named correctly (following the **/*IT.java, **/IT*.java, or the **/*ITCase.java that included by default by Failsafe and excluded by default by Surefire).

Is there any way that I can use JUnit 5 tests with Failsafe?

Answer 1

Note that from the JUnit 5 documentation : junit-platform-surefire-provider should be not used any longer :

Due to the release of Surefire 2.22.0, the junit-platform-surefire-provider from the JUnit team has been deprecated and will be discontinued in a subsequent release of the JUnit Platform.

Additionally, you can also read in the maven-surefire-plugin documentation :

Using JUnit 5 Platform

To get started with JUnit Platform, you need to add at least a single TestEngine implementation to your project. For example, if you want to write tests with Jupiter, add the test artifact junit-jupiter-engine to the dependencies in POM

So you have to specify this test dependency :

<properties>
    <junit-jupiter.version>5.2.0</junit-jupiter.version>
</properties> 

<dependencies>
     [...]
     <dependency>
         <groupId>org.junit.jupiter</groupId>
         <artifactId>junit-jupiter-engine</artifactId>
         <version>${junit-jupiter.version}</version>
         <scope>test</scope>
     </dependency>
     [...] 
</dependencies>

And the maven-failsafe-plugin declaration could be as simple as :

<build>
    <plugins>           
        <plugin>
            <artifactId>maven-failsafe-plugin</artifactId>
            <version>2.22.0</version>
        </plugin>
    </plugins>
</build>
