> Key: SUREFIRE-1918
> URL: https://issues.apache.org/jira/browse/SUREFIRE-1918
> Project: Maven Surefire
> Issue Type: Bug
> Components: Junit 4.7+ (parallel) support
> Affects Versions: 2.22.2, 3.0.0-M5
> Environment: Apache Maven 3.8.1
> Reporter: Martin Schneider
> Priority: Major
> Attachments: parallel-tests.tar.gz
>
>
> Tests don't get executed in parallel with JUnit's vintage engine.
> The following configuration executes them serially:
> {code:java}
> <dependency>
> <groupId>org.junit.vintage</groupId>
> <artifactId>junit-vintage-engine</artifactId>
> <version>5.7.2</version>
> </dependency>
> ...
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-surefire-plugin</artifactId>
> <version>3.0.0-M5</version>
> <configuration>
> <parallel>methods</parallel>
> <useUnlimitedThreads>true</useUnlimitedThreads>
> </configuration>
> </plugin>{code}
>
> Replacing the vintage engine with Junit 4 executes tests in parallel as expected:
> {code:java}
> <dependency>
> <groupId>junit</groupId>
> <artifactId>junit</artifactId>
> <version>4.13.2</version>
> </dependency>
> {code}
>
> I have attached a minimal failing example. {{mvn test}} will produce the following output:
> {code:java}
> [INFO] -------------------------------------------------------

> [INFO] -------------------------------------------------------
> [INFO] Running ParallelTest
> Test 1 running in main
> Test 2 running in main
> Test 3 running in main
> Test 4 running in main{code}
> The expected output (and what I get with JUnit 4) would be:
> {code:java}
> [INFO] -------------------------------------------------------
