Benchmarking Web Applications with Artillery

TLDR; Use the below Dockerfile and test.yml, change some arguments (i.e. the url, endpoints and any variables you need) and you’ll be good to go:

Recently I found myself wanting to find out how well a Quart web app I’ve been making would perform under load, a quick Google search threw up a bunch of options, nothing really jumping out and a whole slew of them seemed to be either just local testing or purely cloud based, neither of which helped me much.

Artillery is a NodeJS application specifically for benchmarking/load testing. It is incredibly easy to set-up, has a ton of possible configuration, a free and pro version and, most importantly for me at least, the free version has nearly everything you could possibly need to test any web app.

I want to make thisd article quick so here are some questions I went through in deciding whether it was right for me:

Can I run this easily, locally and on a server? Yes.
Can I configure this to cover my multiple use cases without making giant, unweildy changes? Yes.
Can I scale the deployment of this if required without much pain? Yes.
Do I need to learn some new language/tools to implement it into my current development workflow? No.

That’s it. It’s easy. I’m sure there are more robust or more intricate or more widely supported tools, but if you need something that works, works well and can be scaled, Artillery.io is a fantastic choice.
