<?php
/**
 * This PHP script defines the spec that the mediawiki.jqueryMsg module should conform to.
 *
 * It does this by looking up the results of various kinds of string parsing, with various
 * languages, in the current installation of MediaWiki. It then outputs a static specification,
 * mapping expected inputs to outputs, which can be used fed into a unit test framework.
 * (QUnit, Jasmine, anything, it just outputs an object with key/value pairs).
 *
 * This is similar to Michael Dale (mdale@mediawiki.org)'s parser tests, except that it doesn't
 * look up the API results while doing the test, so the test run is much faster (at the cost
 * of being out of date in rare circumstances. But mostly the parsing that we are doing in
 * Javascript doesn't change much).
 */

			QUnit.stop();
			getMwLanguage( test.lang, function ( langClass ) {
				var parser = new mw.jqueryMsg.Parser( { language: langClass } );
				assert.strictEqual(
					parser.parse( test.key, test.args ).html(),
					test.result,
					test.name
				);
				QUnit.start();
			} );
		} );
