Hello, I'm happy to announce that the next version of Datatest is now available. This update includes improved data handling features and support for Python 3.7. Datatest supports test driven data-wrangling, data validation, and analysis (for both pytest and unittest style testing). * Docs: http://datatest.readthedocs.io/ * PyPI: https://pypi.org/project/datatest/ * Devel: https://github.com/shawnbrown/datatest What's New in Datatest 0.9.2 ============================ * Changed Query class: * Added flatten() method to serialize dictionary results. * Added to_csv() method to quickly save results as a CSV file. * Changed reduce() method to accept "initializer_factory" as an optional argument. * Changed filter() method to support predicate matching. * Added True and False as predicates to support "truth value testing" on arbitrary objects (to match on truthy or falsy). * Added ProxyGroup class for performing the same operations on groups of objects at the same time (a common need when testing against reference data). * Changed Selector class keyword filtering to support predicate matching. * Added handling to get_reader() to support datatest's Selector and Result objects. * Fixed get_reader() bug that prevented encoding-fallback recovery when reading from StringIO buffers in Python 2.
