Supreme Pack

A skill for Claude Code and Codex · Software and infrastructure

A green test that proves nothing is worse than no test at all.

testes-automatizados-expert doesn't just give you advice on testing, it builds and runs the suite: unit, integration and API, e2e, contract, negative, IDOR, abuse, DAST and load, on ephemeral infrastructure with Docker, far from production. It only calls the job done with a green suite and evidence, and every test carries an assertion that would fail if the bug actually existed.

The problem

High coverage with a weak assertion is theater.

AI generates tests fast, and that's exactly where the risk lives: hundreds of tests that mirror the implementation, mock the database, and pass even with the bug still sitting inside. Three symptoms, and what changes with the skill.

What the work looks like without testes-automatizados-expert and with it
Without the skillWith testes-automatizados-expert
Three hundred unit tests stating the obvious, 90% coverage, and not a single test on the payment flow, where a real error costs money.Risk map first, then a coverage plan by priority, covering the critical path, authorization and money before any decorative test.
The integration test mocks the entire database and still gets called an integration test, so the broken query only shows up in production.Integration testing against a real, ephemeral database in a container, deterministic and isolated test data, and mocks reserved for the external boundary, like gateways and email.
The test caught a real bug, and someone adjusted the test to turn it green, because the goal became passing instead of proving anything.A legitimately red test becomes a reported bug with the request that reproduces it, and the skill pauses for a decision instead of patching the test.

What you get out of it

What you get out of it.

A suite that runs with one command, isolated from production, and a report of what it actually proves.

  • 01

    Coverage plan

    gaps by test type and priority, so nothing gets generated for nothing

  • 02

    Suite in your own style

    using the runner, naming, and style your repository already follows

  • 03

    Security tracks

    IDOR with multiple users, abuse, mass assignment, and a DAST scan

  • 04

    Final report

    coverage per track, findings with reproduction steps, and a load verdict

How it works

You ask for tests. It asks for the risk map.

  1. Scopes out the repository

    Stack, runner, existing tests, CI, and the risk map: authenticated routes, endpoints with an id, money, uploads, and isolation between tenants.

  2. Proposes the coverage plan

    A gap matrix by type and priority, for you to approve before it generates anything in bulk, unless the request was already to generate everything.

  3. Generates in the repository's own style

    Same runner, naming, and style, integration testing against a real database, and IDOR, API, load, and DAST templates adapted to the project.

  4. Runs isolated from production

    Ephemeral database and Redis with Testcontainers or a disposable Compose setup, and the app in a container for the tracks that need a live target.

  5. Verifies and reports

    Green suite, real bugs reported with reproduction steps, a load verdict, and a single command to run everything again.

Before you buy

What you need, and what it never does.

What you need Docker on the machine

  • Claude Code or Codex, either one works
  • Docker for isolated test infrastructure
  • The project's repository, in Node or any other stack it adapts to

k6 and ZAP come in for the load and security tracks, and Claude installs them on its own.

Setup zero

  • Drop the folder into your Claude Code or Codex skills location
  • With Docker running, ask it to generate or run the project's tests
  • Approve the coverage plan, and it generates and runs everything

What it never does by rule

  • Run load or DAST tests against production
  • Call a test with a mocked database an integration test
  • Declare the suite done without having run it
  • Patch a test that caught a real bug just to turn it green
  • Inflate unit tests to hit a coverage target

Its limits

It proves what it tested. It doesn't invent requirements.

The skill covers what the code and the acceptance criteria say. A business rule nobody wrote down doesn't turn into a test on its own, and it flags what needs a decision.

Without Docker it can't spin up the isolated infrastructure that gives the integration, security, and load tracks their value, and it says so instead of testing on a shared environment.

Sizing infrastructure from the load results is the job of teste-de-carga, and the pipeline that runs the suite on every push belongs to ci-cd-expert, both also in the catalog.

Before you ask

Questions about testes-automatizados-expert.

Does testes-automatizados-expert write and run the tests?

Writes and runs them. It's not an advice-only skill: it builds the suite in your repository's own style, spins up isolated infrastructure in Docker, executes it, and only calls the job done with a green result and evidence.

What's an IDOR test, and why does it matter?

It's testing whether one user can read or change another user's data just by swapping the identifier in the request. It's one of the most common API flaws, and the skill tests it with multiple users, in both reads and writes.

Does it work outside of NestJS and React?

It does. It detects the project's stack and swaps in the equivalent tooling before generating a single test.

Does it run tests against my live site?

No. Destructive, load, or DAST tests always run on isolated infrastructure, never against a production database or URL.

Can I use it on a client project?

Yes, the license covers your work for third parties. What's off limits is reselling or redistributing the skill.

A good test is one that fails when the bug is actually there.
