Git Bayesect

open sourceexplicit relation

Git Bayesect applies Bayesian inference to git bisection, solving the problem of finding commits that introduced non-deterministic bugs like flaky tests. Unlike standard git bisect which requires binary pass-fail results, Git Bayesect handles probabilistic outcomes where a test might pass sometimes and fail sometimes, using entropy minimization to efficiently narrow down the culprit commit.

100% free and open-source Bayesian regression locator CLI for flaky and non-deterministic test suites (MIT license, $0 software cost). Installable via pip with zero usage restrictions.
