It is a test-framework agnostic assertion and expectation library, designed to work with your choice of test runner. Some highlights: - Rich library of assertions - Supports custom assertions - Complementary `assert/refute` (`refute` is referee's `assert.not`) - Evented: Emits success and failure events - Failing assertions throw exceptions by default, but can be configured to not - API to add custom assertions that provides quite a bit of plumbing for free - 100% test coverage (enforced with `test-check-coverage` in `package.json`) **referee** works in browsers (including old and rowdy ones, like IE11) and Node ([LTS versions](https://github.com/nodejs/Release#release-schedule)). It will define itself as an AMD module if you want it to (i.e. if there's a `define` function available). ## Documentation https://sinonjs.github.io/referee/ ## Backers Support us with a monthly donation and help us continue our activities.
