rbuckton/chai-baseline

**chai-baseline** is a Node.js library that extends Chai with file-based baseline testing capabilities, allowing developers to compare test data against reference files stored on disk. It's designed for developers writing tests in Node.js who need to validate large outputs or complex data structures against baseline files, enabling integration with external diff tools for comprehensive comparisons. The library supports both `expect` and `assert` interfaces in Chai and returns promises for asynchronous test handling.
