Ember Sinon

Ember Sinon is an Ember CLI addon that seamlessly integrates the Sinon.js testing framework into Ember applications, simplifying the process of creating test spies, stubs, and mocks. The current stable version is 5.0.0, which supports Ember.js v3.16+ and Sinon.js v9.0.0+. Historically, the addon has maintained a consistent release cadence, often aligning its major versions with significant Ember and Sinon updates several times a year. Key differentiators include its tight integration with the Ember CLI test suite, making Sinon globally available in test environments without manual configuration, and its direct compatibility with `ember install` workflows. It offloads the complexity of managing Sinon.js versions and ensuring it's properly hooked into Ember's testing infrastructure, providing a ready-to-use solution for behavior verification in unit and integration tests.
