What it does
Zoonk Testing is an agent skill from zoonk/zoonk. Design, add, or debug Zoonk E2E, database integration, and pure-function tests.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/e2e.md` and `references/integration.md`).
It sits in Testing & QA, covering End-to-end testing. The repository describes itself as: Turn any topic into clear, structured lessons. The licence is MIT.
When your agent uses it
- Tasks that involve End-to-end testing
Example prompts
- “/zoonk-testing”
What it can do on your machine
Read from SKILL.md and the folder at commit e0fe2d6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
mise
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Zoonk Testing loads about 1k tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 23 tokens; SKILL.md has 452 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Zoonk testing
Choose a test boundary capable of exercising the behavior under investigation. Choose the overall set of checks from the affected behavior and consumers. A small regression test may demonstrate one property while broader existing coverage remains necessary for the change. Follow the root verification policy for scope, completion, and reruns.
For behavior changes, prefer a failing regression test before implementation when practical. Confirm it fails for the expected reason. If it already passes, investigate whether the defect is reproduced and whether the assertion distinguishes the intended outcome; do not weaken assertions or manufacture a failure.
Choose coverage
| Behavior | Boundary | Guidance to load |
|---|---|---|
| User flow, browser interaction, or public HTTP endpoint | Playwright against real product routes | E2E |
| Persistence, permissions, transactions, or business orchestration | Vitest with the real test database | Database integration |
| Non-trivial pure transformation or domain rule | Vitest beside the owning code | Exercise the exported behavior with meaningful inputs; no additional reference needed |
| Native behavior | The app's native test tools | Read the owning app's AGENTS.md |
Do not write React component unit tests or add tests for admin, evals, or blog. Do not test static configuration against itself, CSS, copy, prompt wording, Zod internals, or framework behavior. Do not export implementation details solely to test them.
Data and external boundaries
- Create unique records through existing
*Fixture()helpers. Tests that mutate user state need a unique user per test; a fresh browser context does not isolate database state. - Keep shared seeded data read-only. It may serve as a guaranteed structural dependency or a route smoke test, but content assertions and mutations need test-owned records.
- Parallelize independent fixture creation. Tests must work in any order; release contexts and other owned resources, and clean up test-owned state when isolation requires it.
- Do not mock Prisma,
@zoonk/db, repositories, or other persistence APIs for data behavior. Mock only an unavoidable external/platform boundary or a failure that cannot safely be produced with the real dependency, and explain why beside the mock.

Running tests
Use the owning package's scripts and configured test database; do not substitute a development or production database. Confirm any setup/reset command targets the intended disposable database before running it. Relevant local test runs and repairs are part of the authorized implementation work.
Run the affected tests, then broaden only for affected consumers or unresolved risks. Investigate intermittent failures rather than hiding them with retries, forced interactions, weaker assertions, or larger timeouts. Repeat focused coverage for timing, concurrency, fixture isolation, or a reproduced flaky failure; an arbitrary five-run loop is not a completion requirement.
For Vitest, a package-scoped command is mise x -- pnpm --filter <workspace> test <test-file>. E2E build and launch details are in the E2E reference. Report checks accurately, including failures and anything not exercised.
