+/**
+ * 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+ * of being out of date in rare circumstances.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).
+ */
+
+/*
+ * @example QUnit
+ * <code>
+	QUnit.test( 'Output matches PHP parser', function ( assert ) {
+		mw.messages.set( mw.libs.phpParserData.messages );
+		$.each( mw.libs.phpParserData.tests, function ( i, test ) {
+			QUnit.stop();
+			getMwLanguage( test.lang, function ( langClass ) {
+				var parser = new mw.jqueryMsg.Parser( { language: langClass } );
+				assert.equal(
+					parser.parse( test.key, test.args ).html(),
+					test.result,
+					test.name
+				);
+				QUnit.start();
+			} );
+		} );
+	});
+ * </code>

+ * @example Jasmine
