I joined Checkly a few months ago, and because our platform enables you to use Microsoft’s Playwright to run your synthetic monitoring, I started getting my hands dirty with the end-to-end testing framework. I’m a massive fan of learning in public, so I started publishing weekly Playwright tips on YouTube. Did you miss a few videos? Don’t sweat it! Here’s the first collection of Playwright tricks I discovered over the last few months.

An API is an important feature to look for when it comes to making cloud purchasing decisions. Here's why.

Properly testing a service’s APIs to ensure that it can handle production traffic presents many challenges for engineers—SREs need to guarantee the resiliency of their application, while developers must ensure that their features perform well at any given scale. Speedscale is a testing framework built for Kubernetes applications that enables you to load test with real-world production scenarios by replaying actual API traffic that your application has experienced.

In 2021, we partnered with AWS to develop the Datadog Lambda extension which provides a simple, cost-effective way for teams to collect traces, logs, custom metrics, and enhanced metrics from Lambda functions and submit them to Datadog.

The Lambda Telemetry API empowers users to integrate monitoring and observability tools like Site24x7 with their Lambda functions. Site24x7 is an AWS-reviewed Lambda Service Ready Program Partner and is announced as a launch partner in AWS Lambda Telemetry API feature release. Customers, AWS partners, and the serverless community can use the Lambda Telemetry API to receive telemetry streams from the Lambda service, including function, extension logs, and metrics coming from the Lambda platform.

Back in 2020, we covered the launch of Lambda Extensions and the subsequent release of the Lambda Logs API. These features aren’t designed for the average Lambda user. But they allow vendors to build better tools by giving them much-needed access to the Lambda execution environment.

Content management is shifting toward two headless options: Git-based and API-driven. Headless CMS solutions allow developers to edit and manage content easily while still using the front- and back-end tools and platforms they know and love. These Git-based and API-driven CMS solutions give developers a new way to expedite CI/CD processes without compromising product quality. Git is an essential tool for both beginners and seasoned software developers.

Load testing is one of the most common ways to test the resiliency of your applications. In this blog we show how recording production data with Speedscale and exporting to a K6 load tests gives you the best of both worlds. Whether or not it’s important for your organization, there are clear benefits to be had from implementing these types of tests. By doing so, you can: When it comes to load testing, two of the most modern tools are Speedscale and K6.
