Generating end-to-end tests with AI and Playwright MCP

When I started using Playwright, there was a single command that blew me away. I immediately became (and still am) a huge Playwright Codegen fanboy. Playwright's codegen command opens up a browser window, and whatever you do in this window will be recorded. Navigating URLs, clicking links, and filling out form elements—the Playwright inspector records all your actions and generates a Playwright test for you. Magic!

Boba Paradox

It's 2PM on a Thursday. Your engineering team is knee-deep in bugs from a recent release. But what's the Slack channel buzzing about? Not flaky tests. Not integration coverage. Not mocking services. It's whether to order brown sugar boba or taro with oat milk. Let's be honest: for many companies, it's easier to justify $8 on boba than $800 on testing tools. And we're not here to judge-we're here to understand why.

From Guesswork to Guarantees: How Traffic Replay Improves Release Confidence

In modern software development, the pressure to move fast is matched only by the need to get it right. Teams working within the software development lifecycle (SDLC) must constantly balance velocity and quality, ensuring releases are stable, secure, and performant. Traditional software development models often relied on manual verification and human intuition to validate releases; however, as systems have grown in complexity, guesswork is no longer sufficient to meet these rising needs.

Streamline API testing with Proxy Mock! Capture, mock, and replay API calls locally

Alan Mon introduces Proxy Mock, a powerful tool for capturing and replaying API calls. Learn how to effortlessly record inbound and outbound API requests and responses. The demonstration highlights how Proxy Mock operates entirely on your local machine, eliminating the need for cloud services or internet connectivity for testing. See how to set up Proxy Mock, inspect captured API calls (including request/response headers, body, and unique signatures), and leverage it to mock API responses for seamless local testing, ultimately boosting productivity and reducing the need for costly non-production environments.

The Defense-in-Depth Approach To Application Monitoring

In cybersecurity, defense-in-depth is a fundamental principle – you never rely on a single security measure to protect your systems. The same philosophy applies to application monitoring. No single monitoring approach, no matter how sophisticated, can capture every possible failure mode of your application. This is why layered monitoring isn't just a best practice – it's essential risk mitigation.

Announcing Checkly Uptime Monitors: Simple, Scalable, and Built for Developers

When Checkly launched, it was the first of its kind, enabling developers to monitor complex workflows easier than ever using the automation tooling (Playwright, Terraform, etc) they already knew and loved. We’ve helped detect and resolve issues for 1000s of companies—ranging from monitoring crucial log-ins, to purchasing products, to setting up client instances for millions of monthly users But what about the simpler stuff?

Running #playwright Tests in Multiple Environments with Checkly. #sdet #devops

Learn how to efficiently run Playwright tests across different environments without rewriting them. This tutorial covers managing environment variables in Checkly for API and browser checks, handling global and group-specific settings, and integrating with CI/CD processes. Discover the best practices for setting up environment variables, duplicating test groups, and customizing alerts to ensure your checks are environment-specific.

AI-Powered Monitoring with Checkly

Most monitoring tools weren't built for the AI-first world. By nature, traditional monitoring platforms force you out of your natural coding environment and trap you in clunky web interfaces, brittle configuration panels, and rigid APIs. And sadly, when monitoring providers do offer "AI features," it's usually a chatbot bolted onto their existing UI, being nothing more than a pale imitation of the AI tools you’re reading about every day on Hacker News. All this creates friction.
