xmltest

Redistribution of ftp://ftp.jclark.com/pub/xml/xmltest.zip as a npm package to make it easy to access the test cases from javascript. The linked zip file is from http://www.jclark.com/xml/ which describes it's purpose and links more related resources.

There is a different license for xmltest.zip

The zip file contains a readme.html that states:

Copyright (C) 1998 James Clark. All rights reserved. Permission is granted to copy and modify this collection in any way for internal use within a company or organization. Permission is granted to redistribute the file xmltest.zip containing this collection to third parties provided that no modifications of any kind are made to this file. Note that permission to distribute the collection in any other form is not granted.

What is it good for?

It contains may different (test) cases that an XML parser might want to verify it parses correctly. They are sorted into folders: 0. top level xmltest folder

1. The first level declares how "well defined" the contained files are: valid, not well formed (not-wf), invalid
2. The second level separates standalone (sa) files from files that are not standalone (not-sa) or have dependencies to external entities (ext-sa)
3. (Only inside valid) the out folder contains the canonical representation of the test cases, which can be useful as an expected value. (The zipfile also contains canonical.html that described that term in more details.)

Usage

Install

• npm install -D github:karfau/xmltest

In tests

• In you tests:

const xmltest = require('xmltest');
//or import xmltest from 'xmltest';

describe('unit', () => {
    // filter the ones relevant for your tests
    // `{'path/to/file.ext': 'file.ext', ...}`
    const cases = xmltest.getEntries(
        xmltest.filters.VALID.SA.files,
        xmltest.filters.xml
    )
    for (const [pathInZip, filename] of Object.entries(cases)) {
        test(`should match valid standalone ${filename}`, async () => {
            const input = await xmltest.getContent(pathInZip);
            const expected = await xmltest.getContent(
              xmltest.RELATED.relative_out(pathInZip)
            )         
            // your test here
        }); 
    }
});

command line interface

• node xmltest or npx xmltest will print all entries as JSON, similar to calling getEntries
• passing one or multiple arguments will use them with createFilters and return the filtered content in the same way as getContent does:
  • with only one argument and a single matching entry it only returns the content itself
  • otherwise, it returns a json where the keys are the path inside the zip file, and the values are the content

Extract & Inspect zip content

In case the command line interface is not sufficient, npm run extract will extract xmltest.zip into the .gitignored data directory.
