A minimalistic BDD-style assertion library for Node.js and browsers, based on should.js. It provides a chainable expect() API that works standalone with any test framework.
Use cases
- write BDD-style assertions in JavaScript tests
- assert deep equality of objects in unit tests
- use the same assertion library in Node and the browser
- add assertions to tests without a specific test framework
- assert thrown exceptions, types, and object keys
When to choose
- you need lightweight, framework-agnostic assertions
- you must support very old browsers like IE6+
- you want a single standalone global with no prototype extensions
When to avoid
- you need actively maintained assertion features or modern syntax
- your test framework already ships a built-in expect/assert API
- you need async assertion support or rich plugin ecosystems
