    microsoft/playwright-mcp: Playwright Tools for MCP

    Microsoft's Playwright MCP is a Model Context Protocol (MCP) server designed for browser automation using Playwright. It allows LLMs to interact with web pages through structured accessibility snapshots, avoiding the need for vision models. Highlights include fast and lightweight operation, LLM-friendly tools, and deterministic tool application. The MCP supports tasks like web navigation, form-filling, data extraction, and automated testing. It’s installable via VS Code CLI and supports both headless and headed modes. There are two modes: Snapshot Mode (default) for performance and reliability, and Vision Mode for visual interactions.

    Writing tests sucks. Use LLMs so it sucks less.

    The post discusses the challenges and solutions for testing in data engineering. It highlights several key obstacles, such as data variability, complex transformations, and lack of tooling. Tinybird aims to address these issues with tools like 'tb mock' for generating realistic test data, and 'tb test' for validating data transformations. The use of LLMs to handle mundane aspects of test generation is emphasized, making testing less tedious and more efficient.

    You NEED To Update Your Tests in .NET

    Testing in .NET is undergoing significant changes with the release of xUnit version 3. This update introduces numerous new features, including project templates, configuration files, and enhanced test execution capabilities. The package update requires migrating to a new package rather than a simple version upgrade. The Microsoft Testing Platform is a new lightweight alternative to older testing frameworks, now supported in xUnit v3. Features like test pipeline startup, assembly fixtures, and improved assertions make testing more efficient and flexible. Additionally, there are improvements in test context handling, including adding warnings and attachments to test results.
