It only takes a few minutes and most of that is time getting a cup of coffee.
Navigate to this helpful tutorial and run through the installation. One of the easiest ways to try out Kubernetes is to run minikube on your local desktop. If you already have a test Kubernetes cluster, skip this section. To run a load test in Kubernetes, we first need to have a Kubernetes cluster installed. Sign up for a free Speedscale trial here to follow along or use your existing login. This can be very complicated but fortunately Speedscale exists to automate the process.įor the rest of this tutorial we will use Speedscale to automate a full load test from a Postman collection.

Additionally, to run a load test in Kubernetes you also need to orchestrate the load generator and its network connection to your service. For the load test to work, you need to run all the tests at once to create a significant load. Load testing is used to test how an API behaves under constant load. Similarly, groups of HTTP Requests in Speedscale are called Snapshots and can be imported from Postman collections or recorded from live services. Groups of HTTP Requests in Postman are called collections and can be exported as JSON files.

With Postman, it’s possible to easily consume local and internet services, and do load and performance tests on the responses to request cookies, status code, response time, and so on.Īs the use of web APIs continues to grow, Postman will continue to gain traction as it helps developers analyze the functioning of external services so that you know how to consume them. NET, PHP, Node.js, or any other language. Postman is a tool that aims to test RESTful services (web APIs) by sending HTTP/S requests and analyzing the responses. This tutorial will teach you to author requests in Postman and turn them into load tests using Speedscale in less than 15 minutes. Speedscale then takes over and creates repeatable validation on demand or as part of the CI/CD process in Kubernetes.
Typically, engineers write Postman collections using Postman’s excellent UI to bootstrap testing of a new service. Speedscale is a Production Data Simulation Platform that includes this stress/load testing capability out of the box. However, as the service grows you eventually need to test it in a more realistic way with larger volume. These collections are useful for running quick functionality tests as you develop each endpoint. In this Postman load testing tutorial, you’ll learn how to run a large scale load test in Kubernetes using your existing Postman collections.īecause HTTP services don’t have a graphical user interface, it’s common to build collections of requests using Postman during the development process.
