For example, if you want to write tests with Jupiter, you must add the + <<<junit-jupiter-engine>>> to the dependencies like: + ++---+ +<dependencies> + [...] + <dependency> + <groupId>org.junit.jupiter</groupId> + <artifactId>junit-jupiter-engine</artifactId> + <version>5.2.0</version> + <scope>test</scope> + </dependency> + [...] +</dependencies> ++---+ + + This will pull in all required dependencies. Among those dependencies is <<<junit-jupiter-api>>> which contains + the classes and interfaces your test source requires to compile. <<<junit-platform-engine>>> is also resolved and + added. + + This is the only step that is required to get started - you can now create tests in your test source directory + (e.g., <<<src/test/java>>>). + + If you want to write and execute JUnit 3 or 4 tests via the JUnit Platform add the Vintage Engine to your projects' + dependencies: + ++---+ +<dependencies> + [...] + <dependency> + <groupId>org.junit.vintage</groupId> + <artifactId>junit-vintage-engine</artifactId> + <version>5.2.0</version> + <scope>test</scope> + </dependency> + [...] +</dependencies> ++---+ + +* Provider Selection + + If nothing is configured, Surefire detects which JUnit version to use by the following algorithm: + ++---+ +if the JUnit Platform Engine is present in the project + use junit-platform +if the JUnit version in the project >= 4.7 and the parallel attribute has ANY value + use junit47 provider +if JUnit >= 4.0 is present + use junit4 provider +else + use junit3.8.1 ++---+ + + When using this technique there is no check that the proper test-frameworks are present on your project's + classpath. Failing to add the proper test-frameworks will result in a build failure. + +* Running Tests in Parallel + + From JUnit Platform does not support running tests in parallel. + +* Running a Single Test Class + + The JUnit Platform Provider supports the <<<test>>> JVM system property supported by + the Maven Surefire Plugin. For example, to run only test methods in the <<<org.example.MyTest>>> test class + you can execute <<<mvn -Dtest=org.example.MyTest test>>> from the command line. + + +* Filtering by Test Class Names + + The Maven Surefire Plugin will scan for test classes whose fully qualified names match + the following patterns. + + * <<<**/Test*.java>>> + + * <<<**/*Test.java>>> + + * <<<**/*Tests.java>>> + + * <<<**/*TestCase.java>>> + +Moreover, it will exclude all nested classes (including static member classes) by default. + +Note, however, that you can override this default behavior by configuring explicit +`include` and `exclude` rules in your `pom.xml` file.
