Requirements
  • No action required other than to know the goal in performance testing a web or mobile application which is to determine peak scalability of the current deployment. For example, this target application can support 25000 users with a "submit" response time of 2 seconds.
Description

Performance engineering is a niche field with a High Demand and a Low Supply. It's a very lucrative career! Get started!

This basics performance engineering course clearly lays out the process to create a realistic performance test harness. It is intended for technical newbies who are entering the performance engineering field or who want to understand the overall process for load testing web and mobile applications.

These are short videos which clearly articulate each step in the process of creating a performance test harness, from requirement gathering to creating the scripts to execution and results analysis. We took a tool agnostic approach in order to apply what you learn to any load tool! This is the best way to learn - knowing Why a feature is available and When to use it! If you are just starting out or want to further your career in performance engineering, this is a course for you. 

If you are a manager who needs to understand the technology lingo as well as the overall process in order to manage a performance engineering / load testing project, this course is for you too! 

Short videos where you can sit back, relax and passively learn about the basic skill sets for Performance Engineering.
