Use when implementing Python behavior test-first, reproducing bugs, characterizing legacy code, or applying red-green-refactor with pytest/unittest, fixtures, patch lookup, deterministic I/O and clocks, or Hypothesis properties. Covers coverage/mutation limits, not system-wide strategy or benchmarking.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python TDD Target Python **3.15**, checked against **3.15.2 on 2026-11-03**. Use compatible project-pinned runners/plugins; preserve explicit consumer compatibility constraints. ## Route by decision | Need | Default / reference | |---|---| | Feature, regression, legacy behavior; pytest/unittest | Existing runner; named behavioral failure — [Workflow and runners](references/workflow-and-runners.md), including the exact-threshold red/green mutation | | Fixtures, patch targets, doubles, clocks | Fresh mutable state and real local resources — [Isolation and doubles](references/isolation-and-doubles.md) | | Properties, async, HTTP, CLI, database, CI, coverage/mutation | Named examples plus checks at the real boundary — [Properties and boundary checks](references/properties-and-boundaries.md) | ## Workflow 1. **Establish the contract.** Read implementation/callers, neighboring tests, packaging, supported versions, runner/plugins, and CI. Specify inputs/units, outputs, exceptions, state changes, and forbidden effects. Ask the owner about unresolved compatibility or destructive/loss policy before encoding it as a test. …

How to install
mdr add lu1sdv/skillsmd/python-tdd@sha256:cbd8fad58644c409The line at the top of this page pins the label git:20261103.9618ad6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
