Grammar Testing

Unit testing is the best way I've found to really develop a grammar. It allows you to focus on very specific pieces of the grammar at a time, then later put it all together by parsing an entire document.

This library depends upon @easy_link(tlf, php-tests) for testing.

Links:

• Writing a Grammar: @see_file(docs/GrammarWriting.md)
• Grammar Example: @see_file(docs/GrammarExample.md)
• Grammar Commands: @see_file(docs/GrammarCommands.md)

Howto

1. Extend \Tlf\Lexer\Test\Tester which extends from \Tlf\Tester or copy the methods from it & modify as needed for a different testing library.
2. Implement a testGrammarName() method that uses the test runner
3. Implement the data structure for defining the unit tests.

Example of 2.:

@ast(Tlf\Lexer\Test\PhpGrammar, methods.testPhpDirectives.definition) {
@ast(Tlf\Lexer\Test\PhpGrammar, methods.testPhpDirectives.body)
}
