README

Lightweight mocking library for PSR-7 HTTP Message implementations, tailor-made to help you create test suites that are easier to write and maintain.

This library is primarily intended for use in libraries like SDKs that consume PSR implementations without requiring hard dependencies on specific libraries. The library mocks a real-world implementation and strictly adheres to PSR specifications, enabling you to create test suites that are easier to write and maintain. The library also exposes a robust developer API to help you debug and fix test failures substantially faster.

This package is part of the PSR Mock suite of mocking libraries.
