Test Suites for Grammars
|
||
|
|
==========================
|
||
|
|
|
||
|
|
Sentences in the test suite are divided into two classes:
|
||
|
|
|
||
|
|
- grammatical (*accept*) and
|
||
|
|
- ungrammatical (*reject*).
|
||
|
|
|
||
|
|
If a sentence should parse accordng to the grammar, the value of
|
||
|
|
``trees`` will be a non-empty list. If a sentence should be rejected
|
||
|
|
according to the grammar, then the value of ``trees`` will be ``None``.
