How to Load and Performance Test Kubernetes, what is Kubernetes and nuances of the platform

Oct 14, 2024 By Speedscale In Speedscale

Check out Matt LeRay's talk on How to Test in Kubernetes at Star WEST 2024. Distributed architectures like Kubernetes present unique performance challenges. Autoscaling, Load Balancing and other mechanisms help with resiliency but can also serve to cover up fundamental problems. In this video, learn best practices and high level concepts around Kubernetes and achieving high throughput.

How to get started with a local kubernetes development environment

Oct 14, 2024 By Speedscale In Speedscale

Mocks can be useful, but hard to build. You can use them as backends for development, or even tests (like load and performance testing). Speedscale takes the legwork out of building mocks, by modeling them after real observed traffic. This video covers a real-world example of how to use mocks to backend a JMeter load test.

Postman Load Test Tutorial

Oct 11, 2024 By Kasper Siig In Speedscale

Postman is highly popular in the testing tools space for verifying API requests. While its use for general API testing is widely adopted, conducting load testing with Postman is not as straightforward. In this post, we assume that you have some experience working with Postman and are familiar with the fundamentals of creating and sending requests. If you’re new to Postman, there are numerous resources available in the Postman Learning Center.

Top 7 Kubernetes Chaos Engineering Tools

Oct 10, 2024 By Ken Ahrens In Speedscale

Developing highly resilient Kubernetes deployments is crucial for ensuring that your hosted applications in Kubernetes can effectively manage and recover from disruptions. This capability is vital in order to maintain continuous availability for your customers. The importance of resilience in your distributed system also escalates depending on your customer base and the critical nature of your application. Even brief periods of downtime can have a significant negative impact on your business.

Stop Using TCP Health Checks for Kubernetes Applications

Oct 4, 2024 By Shaun Duncan In Speedscale

As developers, one of the most important things we can consider when designing and building applications is the ability to know if our application is running in an ideal operating condition, or said another way: the ability to know whether or not your application is healthy. This is particularly important when deploying your application to Kubernetes. Kubernetes has the concept of container probes that, when used, can help ensure the health and availability of your application.

How to Calculate TPS in Performance Testing: A Kubernetes Guide

Oct 4, 2024 By Kasper Siig In Speedscale

Transactions-per-Second (TPS) is a valuable metric for evaluating system performance and is particularly relevant for engineers overseeing Kubernetes environments.TPS, alongside average response time, provides critical insights into system performance during load testing. This post covers two approaches to calculating TPS; a manual approach applicable in all environments, and an automatic Kubernetes-specific solution using production traffic replication.

Kubernetes Load Testing: How JMeter and Speedscale Compare

Oct 4, 2024 By Kush Mansingh In Speedscale

At some point, your development team may be considering implementing load testing (also known as stress testing) as part of your software testing process. Load testing validates that your web app is able to withstand a large number of simultaneous users, decreasing the chance that any traffic spikes will bring down your services once deployed. These stress tests can be highly granular, giving you the opportunity to test run virtually unlimited strategies before they are set into the wild.

Five Playwright CLI features you should know

Oct 4, 2024 By Stefan Judis In Checkly

Thanks to Microsoft's Playwright, running end-to-end tests with real browsers is quickly done. Initialize a new Playwright project, install all the dependencies, and off you go! Then, any new headless browser test run is only one npx playwright test away. But have you checked all the test command's CLI options? playwright test includes a few real gems to help you create better tests faster. Let me share a mixed bag of my favorite CLI tricks in this post.

How to Mock HTTP APIs With MockServer| Speedscale

Oct 3, 2024 By Kasper Siig In Speedscale

As the name suggests, MockServer is a powerful tool that allows developers to mock HTTP APIs, making it much easier and more efficient to run an integration test in initial development phases. It aims to solve the problem of testing APIs that are still in development or not yet available, allowing developers to make http calls on an http client without a real server.
