Discuss basic functionality testing using Postman and load testing using JMeter to ensure the health and scalability of an event-driven application.
We'll cover the following
This course does not cover a full testing regime across all stages of a DevOps life cycle. However, we’ll walk through the technicalities of performing basic testing to prove the environment is healthy and demonstrate putting a load on the overall application.
