Spring JUnit 5 Testing Support

This project served as the official prototype for JUnit 5 testing support in the Spring TestContext Framework and has been incorporated into Spring Framework 5.0 in conjunction with SPR-13575. Consequently, no further work is planned in this repository in terms of new features: new features are only supported in Spring Framework 5.0+. Note, however, that this project can in fact be used for JUnit Jupiter testing support in conjunction with Spring Framework 4.3.x.

Using the SpringExtension

Currently, all that's needed to use the Spring TestContext Framework with JUnit 5 is to annotate a JUnit Jupiter based test class with @ExtendWith(SpringExtension.class) and whatever Spring annotations you need (e.g., @ContextConfiguration, @Transactional, @Sql, etc.), but make sure you use @Test, @BeforeEach, etc. from the appropriate org.junit.jupiter.api package. See SpringExtensionTests for an example of this extension in action, and check out the source code of SpringExtension if you're interested in the implementation details.

Composing Annotations from Spring & JUnit

Spring has supported composed annotations for several years now, and as of JUnit 5 annotations in JUnit can also be used as meta-annotations. We can therefore create custom annotations that are composed from Spring annotations and JUnit 5 annotations. Take a look at @SpringJUnitJupiterConfig for an example, and check out ComposedSpringExtensionTests for an example of @SpringJUnitJupiterConfig in action.

Building from Source

This project uses a Gradle-based build system. In the instructions below, ./gradlew is invoked from the root of the project and serves as a cross-platform, self-contained bootstrap mechanism for the build.

Prerequisites and Dependencies

• Git
• JDK 8: update 121 or later
• JUnit 5: JUnit Jupiter 5.5.0 and JUnit Platform 1.5.0
• Spring Framework: 4.3.24.RELEASE

Be sure that your JAVA_HOME environment variable points to the jdk1.8.0 folder extracted from the JDK download.

Compile and Test

Compile code, run tests, and build JARs, distribution ZIP files, and docs:

./gradlew build

Install spring-test-junit5 in local Maven repository

./gradlew publishToMavenLocal

Running Tests with Gradle

./gradlew test

Building and Testing with JDK 9, 10, & 11

spring-test-junit5 can also be built with and tested against JDK 9.0.4, JDK 10.0.2, and JDK 11.0.2.

Running Tests in the IDE

In order to execute all of the tests within an IDE as a single suite, simply run SpringExtensionTestSuite as a JUnit 4 test class.
