Description

This test class:

public class StdoutIncrementTest {  
  @Test
  public void testOutput() throws Exception {
    for (int i = 0; i < 1000; ++i) {
      System.out.println("Iteration " + i);
      Thread.sleep(1000);
    }
  } 
}

With this configuration:

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>3.0.0-M5</version>
      </plugin>

there is no output whilst the test is running.

With this configuration:

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>3.0.0-M4</version>
      </plugin>

the output comes out roughly once per second.

This doesn't matter for running tests, but it makes debugging tests a real pain.
