The
testingdependencies were declared as a[project.optional-dependencies]extra, so they shipped in the published package metadata as an installablepytest-env[testing]extra even though no consumer of the plugin needs them. They exist only to develop and test the package itself, which is what PEP 735 dependency groups are for: dependency sets that stay in the source tree and never reach the wheel metadata. 📦This moves the set into a
[dependency-groups]testgroup and points the tox environments that used it atdependency_groups = ["test"]instead ofextras = ["testing"]. The packages and their version constraints are unchanged.The published distribution no longer advertises a
testingextra. Local workflows that installedpytest-env[testing]should use thetestdependency group (--group test) or the tox environments instead. Runtime dependencies stay untouched.
