Hypothesis strategies for generating Python programs, something like CSmith

Project description


Hypothesis strategies for generating Python programs, something like CSmith.

This is definitely pre-alpha, but if you want to play with it feel free! You can even keep the shiny pieces when - not if - it breaks.

Get it today with pip install hypothesmith, or by cloning the GitHub repo. You can run the tests, such as they are, with tox on Python 3.6 or later.


0.0.3 - 2019-08-08

Checks validity at statement level, which makes filtering much more efficient. Improved testing, input validation, and code comments.

0.0.2 - 2019-08-07

Improved filtering and fixing of source code generated from the grammar. This version found a novel bug: "pass #\\r#\\n" is accepted by the built-in compile() and exec() functions, but not by black or lib2to3.

0.0.1 - 2019-08-06

Initial release. This is a minimal proof of concept, generating from the grammar and rejecting it if we get errors from black or tokenize. Cool, but while promising not very useful at this stage.
