The ember‑cli‑blueprint‑test‑helpers package provides a set of Node‑based testing utilities for Ember‑CLI blueprints, letting addon authors quickly scaffold, generate, assert on, and clean up blueprint output within isolated temporary projects. It bundles Chai assertions (with file and promise plugins) and helper functions like `emberNew`, `emberGenerate`, `emberDestroy`, and `emberGenerateDestroy`, making it easy to write automated tests for custom blueprints. It is intended for Ember addon developers who need reliable blueprint test suites.
