hypothesis v4.49.0 Release Notes

Release Date: 2019-11-28 // over 4 years ago
  • ๐Ÿš€ This release significantly improves the data distribution in rule
    โœ… based stateful testing <stateful_testing>, by using a technique called
    โœ… Swarm Testing (Groce, Alex, et al. "Swarm testing." Proceedings of the
    โœ… 2012 International Symposium on Software Testing and Analysis. ACM,
    โœ… 2012.) to select which rules are run in any given test case. This
    should allow it to find many issues that it would previously have
    missed.

    โœ… This change is likely to be especially beneficial for stateful tests
    with large numbers of rules.
