A JUnit extension that generates JFR events.

<dependency>
  <groupId>com.github.marschall</groupId>
  <artifactId>junit4-jfr</artifactId>
  <version>0.1.0</version>

If you can migrate to JUnit 5 and marschall/junit-jfr as it offers much higher fidelity.

• Add a JfrMethodRule to your unit test class, see JfrMethodRuleTest for and example.
• Generate a flight recording from your unit tests, eg using

-XX:StartFlightRecording:filename=recording.jfr
-XX:FlightRecorderOptions:stackdepth=128

public class ProfiledTest {

  @Rule
  public JfrMethodRule jfr = new JfrMethodRule();

  @Test
  public void testMethod() {
    // implementation
  }

}
