   3  * This PHP script defines the spec that the mediawiki.jqueryMsg module should conform to.
   4  *
   5  * It does this by looking up the results of various kinds of string parsing, with various
   6  * languages, in the current installation of MediaWiki. It then outputs a static specification,
   7  * mapping expected inputs to outputs, which can be used fed into a unit test framework.
   8  * (QUnit, Jasmine, anything, it just outputs an object with key/value pairs).
   9  *
  10  * This is similar to Michael Dale (mdale@mediawiki.org)'s parser tests, except that it doesn't
  11  * look up the API results while doing the test, so the test run is much faster (at the cost
  12  * of being out of date in rare circumstances. But mostly the parsing that we are doing in
  13  * Javascript doesn't change much).
