Load Test Your app

Hello there! If you have an app, you definitely want it to work seamlessly, right? Load testing can be compared to a dress rehearsal, which helps to determine if your app can handle the traffic when it really matters. As a developer, after I am done building an app, I often want to check if it can handle the pressure, such as how many requests per second it can handle and how much time it takes to respond to those requests.

Load testing Libraries

to load test your app there are a lot of libraries out there from lightweight tools to more complex one that cover a wide range of conditions and scenarios , I will list some of the libraries that you can use to test your app.

Lightweight Libraries

These libraries are lightweight and easy to use, making them ideal for quick load testing and measuring the performance of your application under moderate loads. However, they may have some limitations, such as limited support for testing more complex scenarios or simulating real user traffic.

1- ApacheBench (ab) >> the one I use frequently
2- hey
3- vegeta
4- fortio
5- boom
6- wrk

For more complex scenarios

These libraries are widely used by developers and QA engineers to simulate high levels of traffic to their applications and measure their performance under various conditions. Each library has its own unique features, strengths, and limitations.

1- Apache JMeter
2- Gatling
3- Locust
4- Artillery
5- k6
6- Tsung
7- Siege
8- The Grinder
9- LoadRunner

Since I like to tire myself out 😅 I always try to recreate a small version of the things I use in a daily basis so in the next article we will building our own small load test app using Node and compare the result with other tools .
