Test suites for language tag software
- Stéphane Bortzmeyer's test suites. The format is "tag
whitespace optional-comment":
- ICU test suite, now apparently only in
the Android source code
- From the grammar in
the RFC, you can use programs like abnfgen or eusthathius to generate tags for testing a
parser. Warning: these tags will follow the grammar but may
not be well-formed, since some rules are not in the grammar (for
instance the rule that no two singletons must be identical).
