This is the third and the last blog post in this three-part series. If you want, you can read the first and second posts. In these previous posts, we discussed load testing and performance testing. With load testing, we can see how the system behaves when there is too much load. With performance testing, we can analyze all the moving parts of the system and optimize them accordingly. Load testing and performance testing analyze existing parts assuming everything is in tact. But what if a part of the system completely breaks down? How will you know what’s going to happen at that point? This is where stress testing comes into picture.   Continue reading “Why Do We Need Stress Testing?” →

This blog post is the second one in this three-part series. If you want, you can read the first and third parts as well. In the previous blog post, we discussed about load testing and how it is useful in determining the behavior of a given system. Load testing is actually a part of the bigger performance testing framework. With load testing, we can understand how the system will behave under extreme load conditions. But what about all the other moving parts of the system? Extreme load is not the only problem a system can face. How do we understand all the constraints of a system? How can we determine what part of the system is going to misbehave in real time? This is where performance testing comes into picture.   Continue reading “Why Do We Need Performance Testing?” →

This blog post is the first one in a three-part series. If you want, you can read the second and third parts as well. Let’s say you are building a website that allows users to create an account, upload photos and browse around. So you will go ahead and define the functionality, design the interface, build the core backend and add all the necessary infrastructure. But how will you know if your design is strong enough the handle everything? How will you know if the website will perform well when a lot of users use it simultaneously? This is where load testing comes into picture.   Continue reading “Why Do We Need Load Testing?” →
