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
