Martin Schneider updated SUREFIRE-1918:
---------------------------------------
Description:
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] 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{code}
The expected output (and what I get with JUnit 4) would be:
{code:java}
