Use when planning which tests an approved set of examples actually needs before any code is written — where each test enters and what it observes, whether a rule those examples already cover deserves a test of its own, and whether a scenario reads in business terms and ends in an outcome a user could observe.
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
# Test Design Mandates
## Overview
Five mandatory rules that govern how tests are designed in a Clean Architecture context. Applied after Gherkin scenarios are written, before any implementation starts.
**Core principle:** Tests enter through a use case boundary and assert at the next visible boundary. Never test internal classes directly.
---
## Mandate 1 — Layer Boundary Enforcement
**Rule:** Every AC names its **use case boundary** — the Application layer entry point the test enters through. All tests at the Application layer enter through that use case. Assertions are made via application interfaces (repositories, gateways) or the use case return value. Never instantiate an internal domain class directly in a test that is exercising Application behaviour.
**Why:** Prevents TBU (Tested But Unwired) defects — production code that works in isolation but is never called through the real composition root.
**Application:**
- Acceptance test → enters through `{UseCaseName}` use case / command handler
- Domain unit test (when extracted) → enters through the domain function or policy's public signature

How to install
mdr add sebastiendegodez/skraft-plugin/test-design-mandates@sha256:0296f880114f11d5The line at the top of this page pins the label git:20260825.81319f4, 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.
