backend-testing SKILL.md skillA
backend-testing from nerds-odd-e/doughnut is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Backend Java tests, controller-level stable-boundary tests, JUnit, @Nested, MakeMe builders, @Transactional, parameterized tests. Use when writing or changing backend JUnit tests.
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
# Backend Testing Rules
**Style ("small test" practice — stable boundary, data over mocks, focused assertions, concise makeMe):** the `unit-testing` skill — follow that first.
## Commands
Run backend verification from the repo root:
```bash
CURSOR_DEV=true nix develop -c pnpm backend:verify
```
When no database migration is involved, this is faster:
```bash
CURSOR_DEV=true nix develop -c pnpm backend:test_only
```
Always run all backend unit tests instead of a selected file or test case.
For `dough-test-optimization`, use `backend:test_only` as both the ordinary
feedback measurement and profiling run. Per-test timings are the `time`
attributes in `backend/build/test-results/test/TEST-*.xml`; keep any derived raw
profile outside committed files. To count Spring context boots, temporarily add
`logging.level.org.springframework.test.context.cache=DEBUG` to
`backend/src/test/resources/application.properties` (a `logback-test.xml`
logger is overridden by the test profile's `logging.level.root=OFF`); each rise
in the logged `missCount` is one boot. Revert it afterwards.
## Core Principles
Backend application of the "small test" style (`unit-testing` skill):

How to install
mdr add nerds-odd-e/doughnut/backend-testing@sha256:219693d517f937faThe line at the top of this page pins the label git:20261003.8204a88, 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.
