We're heading to the stress tests to help us determine whether our application will work for a given number of users using it simultaneously and eventually, to find out the places for optimization. This is undoubtedly very important, as when the application is deployed on the production environment, we usually don't want to discover it went down due to the number of requests and start investigating why and where this happens while our business is out of order :) In today's and the next tutorial, we're also going to test our calculator in 2 popular tools.

Of course, they have in common that they're testing our applications under some stress. These are tests for non-functional requirements, typically performance tests, ones for production hardware specifications, response, or availability.
