Firebase Mock is a library for testing Firebase applications by providing a mock implementation of Firebase SDKs, including the client-side JavaScript API, server-side Admin API, and Firebase Functions. It allows developers to simulate Firebase interactions synchronously or with delays, making it ideal for writing unit and integration tests without relying on actual Firebase services. This tool is designed for developers working with Firebase who want to ensure their code behaves correctly in a controlled, offline testing environment.
