-----------------------------------
Resolution: Not A Bug
> The total amount of threads are not used with test classes nested by
> Enclosed.class.
> ------------------------------------------------------------------------------------
>
> Key: SUREFIRE-1103
> URL: https://jira.codehaus.org/browse/SUREFIRE-1103
> Project: Maven Surefire
> Issue Type: Bug
> Components: Junit 4.7+ (parallel) support
> Affects Versions: 2.16, 2.17
> Environment: JDK 7 on Linux
> JUnit 4.11
> Reporter: Miyata Jumpei
> Assignee: Tibor Digana
>
> It seems that the total amount of threads are not used with test classes
> nested by Enclosed.class.
> For example, I created a project with the following setting.
> {code}
> <plugin>
> <artifactId>maven-surefire-plugin</artifactId>
> <version>2.17</version>
> <configuration>
> <parallel>classes</parallel>
> <threadCount>4</threadCount>
> <perCoreThreadCount>false</perCoreThreadCount>
> </configuration>
> </plugin>
> {code}
> And, create 4 test classes like the following.
> {code}
> @RunWith(Enclosed.class)
> public class Test {
> public static class InnerTest {
> @Test
> public void test1() throws InterruptedException {
> Thread.sleep(1000l);
> }
> }
> }
> {code}
> It takes 4 seconds to execute the 4 tests.
> With 2.15, it takes only 1 second.
> It seems that the outer tests are not parallelly-processed until all inner
> tests are processed.
