Hypothesis-EBNF

===============

A Hypothesis strategy for generating sentences from an EBNF grammar.

Can be imported like any other strategy, and used in the ``given()`` annotation with Hypothesis tests.

.. code-block:: python

	# third-party

	from hypothesis import given

	from nltk.parse.generate import demo_grammar

	# code from this repository

	from hypothesis_ebnf import ebnf

	@given(sentence=ebnf(demo_grammar))

	def test_demo_grammar(sentence):

		"""Use the demo grammar from NLTK to make some test cases."""

		print(sentence)

		assert isinstance(sentence, str)

Installation

------------

This code can currently be installed via GitHub with:

.. code-block:: bash

	$ python3 -m pip install git+https://github.com/cthoyt/hypothesis-ebnf.git@master

Once it's tested better, it will be put on PyPI.
