Martin Schneider updated SUREFIRE-1918:
---------------------------------------
Description:
Tests don't get executed in parallel with JUnit's vintage engine.
The following configuration executes them serially:
{{<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>}}
Replacing the vintage engine with Junit 4 executes tests in parallel as
expected:
{{<dependency>}}
{{ <groupId>junit</groupId>}}
{{ <artifactId>junit</artifactId>}}
{{ <version>4.13.2</version>}}
{{</dependency>}}
I have attached a minimal failing example. {{mvn test}} will produce the
following output:
{{[INFO] -------------------------------------------------------}}
{{[INFO] T E S T S}}
{{[INFO] -------------------------------------------------------}}
{{[INFO] Running ParallelTest}}
{{Test 1 running in main}}
{{Test 2 running in main}}
{{Test 3 running in main}}
{{Test 4 running in main}}
The expected output (and what I get with JUnit 4) would be:
{{[INFO] -------------------------------------------------------}}
{{[INFO] T E S T S}}
{{[INFO] -------------------------------------------------------}}
{{[INFO] Running ParallelTest}}
{{Test 1 running in pool-2-thread-1}}
{{Test 3 running in pool-2-thread-3}}
{{Test 4 running in pool-2-thread-4}}
{{Test 2 running in pool-2-thread-2}}
