cdi-unit-junit5

JUnit 5 Extension for CDI-Unit.

CdiUnitExtension of this project is the JUnit 5 counterpart of the JUnit 4 runner CdiRunner of CDI-Unit.

Usage

import com.github.cschabl.cdiunit.junit5.CdiUnitExtension;

// PER_CLASS lifecycle is supported:
// @TestInstance(TestInstance.Lifecycle.PER_CLASS)
@ExtendWith(CdiUnitExtension.class) // Runs the test with CDI-Unit
class MyTest {
    @Inject
     MyBean beanUnderTest; // This will be injected before the tests are run!
 
      //The rest of the test goes here.
}

Adding cdi-unit-junit5 to your project

Prerequisites

• JUnit 5.4 or higher
• CDI-Unit 5.0.0-EA2 or higher

Maven

Add the cdi-unit-junit5 dependency:

<dependency>
  <groupId>com.github.cschabl.cdi-unit-junit5</groupId>
  <artifactId>cdi-unit-junit5</artifactId>
  <version>2.0-EA2</version>
  <scope>test</scope>
</dependency>

Make sure you've added the CDI-Unit dependency and the preferred Weld SE dependency:

<dependency>
  <groupId>io.github.cdi-unit</groupId>
  <artifactId>cdi-unit</artifactId>
  <version>${cdi-unit-version}</version>
  <scope>test</scope>
</dependency>

<dependency>
  <groupId>org.jboss.weld.se</groupId>
  <!-- or weld-se -->
  <artifactId>weld-se-core</artifactId>
  <!-- Your preferred Weld version: -->
  <version>${weld.version}</version>
  <scope>test</scope>
</dependency>

And the JUnit 5 dependencies:

<dependency>
  <groupId>org.junit.jupiter</groupId>
  <artifactId>junit-jupiter-api</artifactId>
  <version>${junit5-version}</version>
  <scope>test</scope>
</dependency>

<dependency>
  <groupId>org.junit.jupiter</groupId>
  <artifactId>junit-jupiter-engine</artifactId>
  <version>${junit5-version}</version>
  <scope>test</scope>
</dependency>

Gradle

dependencies {
    ...
    testImplementation "org.junit.jupiter:junit-jupiter-api:${junit5-version}"
    testRuntimeOnly "org.junit.jupiter:junit-jupiter-engine:${junit5-version}"

    testImplementation "org.jglue.cdi-unit:cdi-unit:${cdi-unit-version}"
    testImplementation "org.jboss.weld.se:weld-se-core:${weld-version}"

    testImplementation "com.github.cschabl.cdi-unit-junit5:cdi-unit-junit5:2.0-EA2"
    
    ...
}

Restrictions

The following features aren't supported:

• Nested Tests (@Nested)
• Test class constructors with parameters, i.e. JUnit 5 dependency injection to constructors.
• Probably further JUnit-5-specific features.
• CDI extension @io.github.cdiunit.ProducerConfig.

Releases

• 2.x releases are based on CDI Unit 5.x and therefore on Jarkarta EE and Java 11
• Releases < 2.0 are based on CDI Unit 4.x and therefore on Java EE and Java 1.8
