Designing a Test Case
Introduction
It is important to perform load tests, but it is even more important to test with the right scenarios. In this chapter, we will see some tips for designing the most realistic test scenario.
Warning
It's important to understand that a load test is only a simulation. This implies that despite all the possible and imaginable tests, you don't have a 100% guarantee that everything will proceed smoothly in production. There will always be an unplanned case (failure of a part of the system, unanticipated customer action, and so on).
To increase the chances of success, it's important to also work on the architecture (design for failure and so on) and the deployment process (canary release and so on).
Despite this, a load test is important to:
- Put into production the healthiest application
- Fine-tune as much as possible the architecture and application
- Reproduce a performance or multithreading issue detected in production...
