[![Reproducible Builds](https://img.shields.io/badge/Reproducible_Builds-ok-green?labelColor=1e5b96)](https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/us/abstracta/jmeter/jmeter-java-dsl/README.md)



Simple Java API to run performance tests, using [JMeter] as engine, in a Git and programmers friendly way.



If you like this project, **please give it a star :star:!** This helps the project be more visible, gain relevance, and encourage us to invest more effort in new features.



[Here](https://abstracta.github.io/jmeter-dotnet-dsl) you can find the .Net DSL.



Please join [discord server](https://discord.gg/WNSn5hqmSd) or create GitHub [issues](https://github.com/abstracta/jmeter-java-dsl/issues) and [discussions](https://github.com/abstracta/jmeter-java-dsl/discussions) to be part of the community and clear out doubts, get the latest news, propose ideas, report issues, etc.



## Usage



If you use [maven](https://maven.apache.org/what-is-maven.html), just include the following dependency:



```xml



  us.abstracta.jmeter

  jmeter-java-dsl

  1.26

  test



``` 



Here is a simple example test in [JUnit 5](https://junit.org/junit5/)+ with 2 threads/users iterating 10 times each to send HTTP POST requests with a JSON body to `http://my.service`:



```java

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.apache.http.entity.ContentType;

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")

          .post("{\"name\": \"test\"}", ContentType.APPLICATION_JSON)

      ),

      //this is just to log details of each request stats

      jtlWriter("target/jtls")

    ).run();

    assertThat(stats.overall().sampleTimePercentile99()).isLessThan(Duration.ofSeconds(5));

  }

  

}

```



> This example also uses [AssertJ](https://joel-costigliola.github.io/assertj/assertj-core-quick-start.html) for assertions, but you can use whatever assertion library you choose.



More examples can be found in [tests](jmeter-java-dsl/src/test/java/us/abstracta/jmeter/javadsl)



You can use [this project](https://github.com/abstracta/jmeter-java-dsl-sample) as a starting point.



> **Tip 1:** Check [the DSL recorder](https://abstracta.github.io/jmeter-java-dsl/guide/#dsl-recorder) and [jmx2dsl](https://abstracta.github.io/jmeter-java-dsl/guide/#dsl-code-generation-from-jmx-file) to ease test plan creation or migration from existing JMX files.

>

> **Tip 2:** Since JMeter uses [log4j2](https://logging.apache.org/log4j/2.x/), if you want to control the logging level or output, you can use something similar to the tests included [log4j2.xml](jmeter-java-dsl/src/test/resources/log4j2.xml).

>

> **Tip 3:** When working with multiple samplers in a test plan, specify their names to easily check their respective statistics.



**Check [here](https://abstracta.github.io/jmeter-java-dsl/) for details on some interesting use cases**, like running tests at scale in [BlazeMeter](https://www.blazemeter.com/) or [OctoPerf](https://octoperf.com/), saving and loading test plans from JMX, publishing test metrics to [InfluxDB](https://www.influxdata.com/products/influxdb-overview/) (and visualizing them from [Grafana](https://grafana.com/)), and general usage guides.

## Contributing & Requesting features



Currently, the project covers the most used features required when implementing JMeter performance tests, but not everything the JMeter supports/provides.



We invest in the development of DSL according to the community's (your) interest, which we evaluate by reviewing GitHub stars' evolution, feature requests, and contributions.



To keep improving the DSL we need you to **please create an issue for any particular feature or need that you have**.



We also really appreciate pull requests. Check the [CONTRIBUTING](CONTRIBUTING.md) guide for an explanation of the main library components and how you can extend the library.
