This project serves as the official prototype for JUnit 5 testing support in the Spring TestContext Framework which will eventually be incorporated into Spring Framework 5.0 in conjunction with SPR-13575.

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.

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.

There are currently no downloadable artifacts for this project. However, if you install in a local Maven repository (see below) the generated artifact will correspond to the following.

• Group ID: org.springframework.test
• Artifact ID: spring-test-junit5
• Version: 1.0.0.BUILD-SNAPSHOT

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.

• Git
• JDK 8: update 60 or later
• JUnit 5: JUnit Jupiter 5.0.0-SNAPSHOT and JUnit Platform 1.0.0-SNAPSHOT
• Spring Framework: 4.3.0.RELEASE

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

Build all JARs, distribution ZIP files, and docs:

./gradlew build

./gradlew install

Executing gradlew clean test from the command line should result in output similar to the following.

:junitPlatformTest

Test run finished after 1902 ms
[        37 tests found     ]
[         0 tests skipped   ]
[        37 tests started   ]
[         0 tests aborted   ]
[        37 tests successful]
[         0 tests failed    ]

spring-test-junit5 can be built with and tested against JDK 9 early access builds using Gradle 3.0 nightly builds.

For example, we can use a Gradle 3.0 nighty build as follows.

$> gradlew wrapper --gradle-distribution-url=https://services.gradle.org/distributions-snapshots/gradle-3.0-20160615000025+0000-bin.zip
$> gradlew -version
$> gradlew clean test

Assuming we have OpenJDK 9-ea+122 installed, the above will result in output similar to the following.

BUILD SUCCESSFUL

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