Package Exports

unexpected-dom

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 (unexpected-dom) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

unexpected-dom

A plugin for unexpected that adds custom assertions form DOM elements.

The aim is to lower the amount of mocking around in the DOM in your tests and keep your tests easily readable while providing a high powered set of functionality with unsurpassed error messages.

Installation and usage

NodeJS

npm install unexpected unexpected-dom

Bower

bower install unexpected unexpected-dom

Setup in tests:

var unexpected = require('unexpected').clone();
unexpected.installPlugin(require('unexpected-dom'));

describe('in a document', function () {
  it('should find a DOM node', function () {
    expect(document.body, 'to have attributes', {
      id: 'app',
      lang: 'en-US'
    });
  });
});

Assertions

Assertions that test none, singular an plural of a possible collection generally work in all the forms ou would expect. For example to have no children, to have child, to have children.

Brackets in an assertion means the word is an optional flag.

To have attributes

Tests for the existence of DOM element attributes

expect(node, 'to [only] have attribute', 'id');
expect(node, 'to [only] have attributes', 'id', 'class');
expect(node, 'to [only] have attributes', ['id', 'class']);
expect(node, 'to [only] have attributes', {
  'id': 'foo',
  'class': 'bar baz'
});

To have children

Queried for

When parsed as HTML

Parses the subject (string) as an HTML document using the facilities available in the browser, with a fallback to jsdom, then delegates to the next assertion in the argument list:

expect(
    '<html><body><div class="foo"></div></body></html>',
    'when parsed as HTML',
    'queried for', 'div',
    'to have attributes', { class: 'foo' }
);
