culpip
Find which dependency update broke your tests.
You upgraded 30 packages and the tests went red. culpip bisects the change
between two pinned states (requirements.txt or uv.lock) and points at the
culprit, including packages that only break together (delta debugging).
Each trial runs your tests in a throwaway venv.
Usage
culpip --good requirements.old.txt --bad requirements.txt --test "pytest -x"
culpip --good uv.lock.old --bad uv.lock --test "pytest -x"
Inputs can be fully pinned requirements (name==version, e.g. from
uv pip compile or pip freeze) or uv.lock files (detected automatically).
Get the old lockfile with e.g. git show HEAD~1:uv.lock > uv.lock.old. Each trial builds a throwaway venv (using uv if available,
otherwise venv + pip) and runs your test command in it.
Add --editable if your tests need the project itself installed.
Status
Alpha (0.0.1). Supported: pinned requirements.txt and uv.lock
(registry packages only; git/path/url dependencies are ignored with a
warning; lockfiles that pin one package at several versions via resolution
markers are rejected for now).
Planned: poetry.lock, pylock.toml, git refs, grouping by
direct dependency, finding the first bad version inside one package.
