Use before finishing any backend implementation in this Spring Boot repo — to choose the right evidence (unit, ownership, filter-chain, PostgreSQL, @TempDir, SSE), write focused JUnit 5 + Mockito + AssertJ tests, run the narrowest Gradle command, and report results honestly.
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 — Playbook
> **Role:** HOW to prove a change. Binding evidence rules + setup facts: `skills/backend/TESTING.md` (read it too).
> **Requires:** `backend-core`.
## Step 1 — pick the evidence
Match the boundary you changed to a row of the evidence matrix in `TESTING.md`. Typical picks:
| You changed | Minimum evidence |
|---|---|
| Service method | Unit test: happy path + one failure path |
| Controller handler | Unit test on the controller with mocked service (status + body + error) |
| Owner-scoped read/write | Not-owned id → `404` and `verifyNoInteractions(downstream)` |
| Route access / filter / tokens | Filter-chain HTTP test (cookie + Bearer). If no harness exists, say so in the report |
| Migration / native SQL / MyBatis XML | Run on disposable PostgreSQL, or report "not validated on PostgreSQL" |
| Files | `@TempDir` test: traversal rejected, other owner rejected, cleanup on failure |
## Step 2 — write the test
Place it next to the existing ones: `src/test/java/com/bekaku/api/spring/{controller/api|serviceImpl}/{Subject}Test.java`.
```java
@ExtendWith(MockitoExtension.class)
class {Model}ControllerTest {
@Mock {Model}Service service;

How to install
mdr add bekaku/java-spring-boot-starter/backend-testing@sha256:79065cb72beba39fThe line at the top of this page pins the label git:20260924.15dc64a, 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.
