testisolation (Python)
Uncompromising test isolation: your tests structurally cannot touch your real files, secrets, or git identity -- First-class support for Go, Python with pytest, and TypeScript with Node
This is the pytest plugin.
pip install testisolation
Installing it is adoption: the plugin loads through its pytest11 entry point
and refuses to run a suite that has not declared its safety stance.
