Extension for the hypothesis framework to support the generative testing with CSV input

hypothesis-csv's Issues

Missing module multimethod

I'm using Python 3.7 along with conda. The hypothesis_csv library seems to be broken.

In [1]: import hypothesis

In [2]: from hypothesis import given

In [3]: from hypothesis_csv.strategies import csv

Add `Framework :: Hypothesis` PyPI trove classifier

The Python Packaging Authority has recently created a new trove classifier to help users find Hypothesis-related packages, as described and demonstrated in HypothesisWorks/hypothesis#1663.

It would be great if this package used it too!

Failed test case - test_csv_columns_and_header_seq

I installed and ran the test cases. This was done against https://github.com/jeffbr13/hypothesis-csv from @jeffbr13 because of the Iterable problem.

When I installed in a venv and ran the test cases with pytest I got the following failure.

   AssertionError: assert ['text', 'int', 'int'] == ['text', 'int', 'float']
     At index 2 diff: 'int' != 'float'
     Full diff:
     - ['text', 'int', 'float']
     ?                  ^^^^
     + ['text', 'int', 'int']
     ?                  ^^
   Falsifying example: test_csv_columns_and_header_seq(
       data=data(...),
   )

Python 3.10 AttributeError: module 'collections' has no attribute 'Iterable'

Hi there! Just thought I'd let you know that the deprecated abstract base classes aliases were removed in Python 3.10 (change) and this is causing an AttributeError wherever collections.Iterable etc. are used.

The fix is to replace collections.Iterable and similar lookups with collections.abc.….
