Js"> Mocha TDD and Chai assert styles The Mocha TDD interface uses different names for the same basic units: • suiteSetup() and setup(): These are aliases for before() and beforeEach() • suiteTeardown() and teardown(): These are aliases for after() and afterEach() • suite(): This specifies a test suite (describe() in BDD) • test(): This defines a single test function (test() in BDD) The Chai assert style is usually associated with TDD-style tests and provides an assert object with single function assertions.

Com/). View object is the glue that binds models, collections, and templates together with the browser environment and DOM. js is deliberately agnostic as to what a view must do, but a typical view references a collection or a model, couples data to the user interface via a template, and mediates user interaction and backend server events. js template acts like an MVC view. js programs are commonly developed as single-page applications in which the entire HTML page source and JavaScript libraries are downloaded in a single page load.

See the Chai API documentation for a full listing of aliases. Chaining objects and assertions Chai's BDD interface exposes objects that can be chained together to make test assertions more comprehensible. js. a("string") uses the chain objects to and be, which simply proxy through the eventual assertion. In this manner, Chai allows us to add any of the chain objects to, be, been, is, that, and, have, with, at, and of to form more naturally readable assertion statements. The statements a and an are available as both assertion chains and comparison functions.
