Ember CLI Blueprint Test Helpers

ember-cli-blueprint-test-helpers provides a dedicated suite of testing utilities for `ember-cli` blueprint authors. It enables comprehensive testing of blueprint generation and destruction logic by mocking the `ember-cli` environment, allowing developers to simulate `ember generate` and `ember destroy` commands within a controlled context. The current stable version is `0.19.2`, with releases occurring periodically to address bugs and introduce minor enhancements, rather than a fixed cadence. A key differentiator is its specialized focus on blueprint testing within Ember addon projects, providing helpers like `setupTestHooks`, `emberNew`, `emberGenerate`, `emberDestroy`, and `emberGenerateDestroy` to streamline the assertion process for generated and removed files, including support for Module Unification setups. This package is crucial for ensuring the correctness and stability of `ember-cli` blueprints.
