Usage

Add the package to your project:

dotnet add package Abstracta.JmeterDsl --version 0.5

Here is a simple example test using Nunit+ with 2 threads/users iterating 10 times each to send HTTP POST requests with a JSON body to http://my.service:

using System.Net.Http.Headers;
using System.Net.Mime;
using static Abstracta.JmeterDsl.JmeterDsl;

public class PerformanceTest
{
    [Test]
    public void LoadTest()
    {
        var stats = TestPlan(
            ThreadGroup(2, 10,
                HttpSampler("http://my.service")
                    .Post("{\"name\": \"test\"}", new MediaTypeHeaderValue(MediaTypeNames.Application.Json))
            ),
            //this is just to log details of each request stats
            JtlWriter("jtls")
        ).Run();
        Assert.That(stats.Overall.SampleTimePercentile99, Is.LessThan(TimeSpan.FromSeconds(5)));
    }
}

Java 8+ is required for test plan execution.

More examples can be found in tests

Here is a sample project for reference or for starting new projects from scratch.

Tip 1: When working with multiple samplers in a test plan, specify their names to easily check their respective statistics.

Tip 2: Since JMeter uses log4j2, if you want to control the logging level or output, you can use something similar to the tests included log4j2.xml, using "CopyToOutputDirectory" in the project item so the file is available in dotnet build output directory as well (check [Abstracta.JmeterDsl.Test/Abstracta.JmeterDsl.Tests.csproj]).

Contributing & Requesting features

Currently, the project covers some of the most used features of JMeter and JMeter Java DSL test, but not everything, as we keep improving it to cover more use cases.

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 guide for an explanation of the main library components and how you can extend the library.
