Ensuring software quality with integration testing

Before the Raygun API limited release last year, we'd been consistently receiving requests for a public API for a long time, to provide a way for our customers to access their Raygun data programmatically. We're now proud to say we're providing a public API with a range of endpoints, but it took us a lot of planning and development to get here! In this post, I'd like to take you back to the beginning of development on our big API project. Specifically, I want to walk through the pivotal decisions we made around testing when we started development on the project, and how (and why) these have paid off.

Parallel Scheduling Is Now GA: Detect Regional Outages Up to 20x Faster

I am happy to announce that Checkly now supports parallel scheduling as a new way to schedule your checks. Parallel scheduling allows you to reduce mean time to detection, provide better insights when addressing outages, and give improved accuracy in performance trends, making it a powerful new feature for all Checkly users.

Observability with OpenTelemetry and Checkly

Observability isn't just a buzzword; it's a vital compass guiding us through the maze of system health and performance.

How to deal with API rate limits

When I first had the idea for this post, I wanted to provide a collection of actionable ways to handle errors caused by API rate limits in your applications.

API rate limiting is a minefield, and at the time of writing, there are no published standards in terms of how to build and consume APIs that implement rate limiting.

A Guide to Visual Regression Testing With Playwright and How to Get Started

I’m pretty sure that you’ve had a situation where you deployed a major UX change on your web app and missed the most obvious issues, like a misaligned button or distorted images. Unintended changes on your site can cause not only a sharp decline in user satisfaction but also a large fall in sales and customer retention. By identifying and resolving these discrepancies before the update went live, you could have prevented these outcomes.

Monitoring an Open Banking Flow With Playwright & Checkly

Open banking offers users a way to have easier access to their own bank account information, like via third-party applications. This is achieved by allowing third-party financial service providers access to the financial data of a bank's customers through the use of APIs, which enable secure communication between the different parties involved.
