This is a aubclass of Template::TT3::Test with some extra methods for testing the Template::TT3::Parser module.
TODO: this documentation needs writing.
NOTE: these docs are cut-n-pasted from a previous version and are out of date.
Method to test the parser by feeding each test in the __DATA__ section into the parse_expression() method (or a method defined in a 'parse_method' option or set in a test in a -- parse_method_name -- flag) called against a parser object passed in the 'parser' option or defaulting to a Template::Parser object. Then feeds the output into a generator (the 'generator' option) which defaults to Template::Generator::Debug, and can also be controlled by a test flag such as -- generate_perl -- to invoke the 'perl' generator in the generators test set, passed as the 'generators' option or defaulting to the set returned by test_generators().
TODO: wrapper around test_expect() for testing the parser.
