// XamlParser.cs - NUnit Test Cases for the xaml parser
// 
// Iain McCoy (iain@mccoy.id.au)
//
// (C) iain@mccoy.id.au
// 
//
// As you may be aware, testing a parser is something of a beastly job. The
// approach taken by these tests is to feed a file to XamlParser and see if it
// tells the code generator to do what you'd expect. This tests both the parsing
// and type-checking bits of XamlParser.
//
// The various Happening classes each represent methods on the XamlWriter
// interface that XamlParser could call. The constructor of a Happening takes 
// the same arguments as the XamlWriter method it represents, and merely stashes
// those values in the suitable public fields.
//
// The ParserTester class takes a Xaml document and a list of Happenings, and 
// handles comparison of the calls to ParserTester's methods to the expected 
// sequence of Happenings.
//
// I think this strikes a tolerable balance between the need to keep the tests 
// simple and the need to avoid writing 10 zillion lines of hard-to-follow test
// code.
