    Hello everybody I'm Nick and in this video I am to show you how you can get started very quickly and easily with Load Testing. I am going to use a tool called K6 for that because of how low the barrier for entry is but also how extensible the tool itself can be.

    What would be interesting is if you included an example of 'here is an example of an API that where stressing it caused it to fail.' Then apply some fix, run it again, and compare resulting metrics.
    But great video/idea.

    We use NBomber. It is C# based (well, there is F# underneath). As I understand, it should have very similar functionality. But it is C#.
    We were very reluctant to support anything in not-C# and NBomber covers most of our needs.
    There was a bit of a struggle with implementing load tests. But in 9 cases out of 10 it was because of a lack of performance testers in the project and not a fault of the framework.

    • @nickchapsas
      @nickchapsas  2 года назад +2

      NBomber is significantly less consistent in my experience and less performant.

    • @drkrovischa
      @drkrovischa 2 года назад

      @@nickchapsas If I remember right, NBomber was initially an internal project for testing a gambling system. And they have some ridiculous number of request - like thousands per second. I would think that they would want to see pretty consistent results.
      On our meagre 30-50 request per second, I haven't noticed any significant inconsistencies.
      Though from the video I see that K6 gives much more detailed result log.
      In case of our project, we decided that we should stick to the C#. In my experience, it is much easier to get other engineers involved with whatever thing you are doing if it is in the same language as the main project. After working for 5 years on a project where development and autotesting were in two different languages, I would rather fight a herd of radioactive monkeys than support anything on Ruby.-)

    In a CD pipeline which environment would you run these tests against? Would you build a production like environment to run them?

    • @dandoescode
      @dandoescode 2 года назад +1

      For any commercial system, you should ideally have an environment that mirrors production in terms of performance, but has different data stores. e.g. PRE-PRODUCTION. You could configure K6 as part of the deployment pipeline for your PRE-PRODUCTION environment so that you can easily see performance improvements or degradation over time.
      You could also set up the same thing in your QA pipeline. Although the actual numbers would be different to a production like environment, you could still get a sense of performance degradation or improvement.

  • @PelFox
    @PelFox 2 года назад

    Hi Nick, great video and very interesting topic. If this is part of your pipeline, let's say for production deployment. Do you target production or do you set-up a temporary environment or even a slot to load test against? Running load test on the actual production env could affect current users right?
    Also I wonder how you deal with authentication using JWT, can you do some automated refresh step? Since the token would expire running those hour long tests.

    • @billyterblanche
      @billyterblanche 3 года назад

      I think this is something that would need to run on a nightly schedule and not after each push. That way it does not block the build pipeline and you still get performance results daily. If needed you should also be able to run this type of build manually if there is a need to push something out to production and you want to ensure that there is no performance degradation before releasing any code. It all depends on what you want...

Each endpoint with a separate Load.js, spike.js, etc? Or is it possible to use the same .js file for multiple endpoints; if yes, how does the code look like?Thanks
