Can we do latency checks using DSL as in K6?
If possible appreciate someone share some code sample

Hi there!

As far as I know, there isn't an exact equivalent to the latency check in K6.

However, for time validations, you can make assertions on the entire set of sample results (the TestPlanStats) using a library like AssertJ. Here's an example:

import static org.assertj.core.api.Assertions.assertThat;
import static us.abstracta.jmeter.javadsl.JmeterDsl.*;

import java.io.IOException;
import java.time.Duration;
import java.time.Instant;
import org.junit.jupiter.api.Test;
import us.abstracta.jmeter.javadsl.core.TestPlanStats;

public class PerformanceTest {

  @Test
  public void testPerformance() throws IOException {
    TestPlanStats stats = testPlan(
        threadGroup(2, 10,
            httpSampler("http://my.service")
        ),
        //this is just to log details of each request stats
        jtlWriter("target/jtls")
    ).run();
    assertThat(stats.overall().sampleTimePercentile99()).isLessThan(Duration.ofSeconds(5));
  }

}

If this is a feature you'd like to see supported, consider submitting an issue in the repository or, even better, contributing the functionality yourself.

Thanks!
