Backbone assertions for the Chai assertion library

Package Exports

  • chai-backbone

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (chai-backbone) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

chai-backbone

chai-backbone is an extension to the chai assertion library that provides a set of backbone specific assertions.

Usage

Include chai-backbone.js in your test file, after chai.js (version 1.0.0-rc1 or later):

<script src="chai-backbone.js"></script>

Use the assertions with chai's expect or should assertions.

Assertions

trigger

model.should.trigger("change", with: [model]).when -> model.set attribute: "value"

this can also be chained further:

model.should.trigger("change").and.trigger("change:attribute").when -> model.set attribute: "value"
model.should.trigger("change").and.not.trigger("reset").when -> model.set attribute: "value"

route.to

Tests if a route is delegated to the correct router and if the arguments are extracted in the expected manner.

"page/3".should.route.to myRouter, "openPage", arguments: ["3"]
"page/3".should.route.to myRouter, "openPage", considering: [conflictingRouter]

call

This assertion is ideal for testing view callbacks it will rebind view events to test DOM events

view.should.call('startAuthentication').when ->
  view.$('a.login').trigger 'click'
