testing from toongri/oh-my-toong-playground is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add toongri/oh-my-toong-playground/testing@git:20260401.829a4a9

Pins git:20260401.829a4a9 in mdr.lock. Pin the fingerprint instead.

Use when writing tests in this Java/Spring project, generating test skeletons, deciding mock strategies, learning test patterns, or understanding test levels. Triggers include "테스트 작성", "테스트 패턴", "mock 전략", "test skeleton".

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

# Testing Skill

Test writing standards and quality guidelines following Classical TDD (state verification only).

## Quick Reference

| Test Level  | File Pattern               | When to Use                                 | External Deps            |
|-------------|----------------------------|---------------------------------------------|--------------------------|
| Unit        | `*Test.java`               | Domain logic, value objects, pure functions | None                     |
| Integration | `*IntegrationTest.java`    | Service + Repository, transactions          | Real DB                  |
| Concurrency | `*ConcurrencyTest.java`    | Locking, race conditions                    | Real DB                  |
| Adapter     | `*AdapterTest.java`        | External API clients, queries               | WireMock, Testcontainers |
| E2E         | `*E2ETest.java`            | Full API flow, auth                         | Full stack               |
| Batch       | `*BatchTest.java`          | Spring Batch jobs                           | Real DB                  |

## Core Philosophy

Tests serve three purposes: verify correctness, document behavior, and enable safe refactoring.

How to install

The exact contents, by fingerprint
mdr add toongri/oh-my-toong-playground/testing@sha256:490311f90774600e

The line at the top of this page pins the label git:20260401.829a4a9, 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.
