This repository is an ESLint plugin for the Vitest testing framework, providing over 60 lint rules to enforce best practices, catch common errors, and maintain code style in test files. It is a library consumed by ESLint, not a standalone application. The plugin exports a flat config (recommended, all) and an environment configuration for Vitest globals. The codebase is well-structured with a consistent rule creation pattern using a factory utility (`createEslintRule`), centralized Vitest function call parsing (`parseVitestFnCall`), and a reusable padding rule factory (`createPaddingRule`). It relies on `@typescript-eslint/utils` for AST analysis and is designed for ESLint v9+ with flat config. The project is actively maintained with CI/CD, automated releases, and comprehensive test coverage for each rule.
