Equivalent XML JS

Equivalent XML JS is designed to ease the process of testing XML output. The work is a port of equivalent-xml

Comparing text output is brittle due to the vagaries of serialization.
Attribute order doesn't matter.
Element order matters sometimes, but not always.
Text sometimes needs to be normalized, but CDATA doesn't.

Usage

> var doc1 = EquivalentXml.xml("<root><foo a='1' b='2'>Hello</foo><bar>World</bar></root>");
> var doc2 = EquivalentXml.xml("<root><bar>World</bar><foo b='2' a='1'> Hello </foo></root>");
> EquivalentXml.isEquivalent(doc1,doc2);
true
> EquivalentXml.isEquivalent(doc1,doc2, {element_order: true});
false
> EquivalentXml.isEquivalent(doc1,doc2, {normalize_whitespace: false});
false

Options

{element_order: true }

Require elements to be in the same relative position in order to be considered equivalent.

{normalize_whitespace: false }

Don't normalize whitespace within text nodes; require text nodes to match exactly.

Using with Jasmine

In your SpecHelper.js file add:

beforeEach(function() {
  this.addMatchers(EquivalentXml.jasmine);
});

Then in your tests you can write

 expect(node_1).beEquivalentTo(node_2);
 expect(node_1).not.beEquivalentTo(node_2);
 expect(node_1).beEquivalentTo(node_2,{element_order: true});

Install tools

If you want to test or build the source you will first need to install Ruby and Bundler. Once you have this:

$ bundle install

Building the source with dependencies

$ mkdir build
$ rake build

Tests

All of the tests are written in Jasmine. Sprockets is used to describe dependencies between the files. To start jasmine run:

$ rake jasmine

Open your browser to http://localhost:8888

If you want to run the tests directly in the console just type:

$ rake jasmine:ci
