Automatically detects, executes, and analyzes tests across multiple programming languages and frameworks.
The Universal Test Runner skill empowers Claude to act as an intelligent test orchestrator by automatically identifying a project's ecosystem—whether it's Node.js, Python, Rust, or Go—and executing the correct testing commands. It streamlines the development workflow by handling complex tasks like pattern matching, coverage reporting, and watch modes, while providing structured summaries of pass/fail counts and actionable suggestions for fixing broken tests or improving coverage gaps.
