Stress Test with Gatling
Test is a very important part of software development. Everybody agree and some people(sadly not everybody yet) do lots of unit testing, some do integration tests other do some kind of UI testing as well. But thats not enought you are into SOA/microservice land. As much as you distribute your software you have way more wants to fail. Tests need to catch up, Stress test are something that unfortunately people dont do - sometimes they do but when they know that there is a scalability problem witch is sad. This practice of stress tests could be automated(it really should) or at least make sure you run periodically as far as i know Netflix does 2-3 times per week - because this is not just about scalability. Stress Tests are bigger than just how many users can i handle.
