What it does

TDD With Pest is an agent skill from dev-toolings/superpowers-symfony. Apply RED-GREEN-REFACTOR with Pest v4 (PHP 8.3+) for Symfony via the PHPUnit bridge; Foundry factories, WebTestCase, verify failures first

Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `reference.md`).

It sits in Testing & QA, covering Test-driven development. It works with Symfony and PHP. The repository describes itself as: Claude Code plugin for Symfony 7.4 LTS & 8.x — 44 skills, 7 AI subagents & 13 commands for API Platform v4, Doctrine ORM 3, TDD (Pest/PHPUnit), Messenger, security & DDD. The licence is MIT.

When your agent uses it

  • Tasks that involve Test-driven development

Example prompts

  • “/tdd-with-pest”

Requirements

  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Write, Edit, Bash

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Confirm PHP 8.3+ and Pest v4, then generate tests/Pest.php with ./vendor/bin/pest --init.
  2. Bind the bridge classes in tests/Pest.php: uses(KernelTestCase::class, Factories::class, ResetDatabase::class)->in('Integration') and…
  3. RED: write an it() test with Foundry v2 factories, run ./vendor/bin/pest --filter and check it fails for the right reason.
  4. GREEN: write the minimal code, then REFACTOR and re-run ./vendor/bin/pest.
  5. Gate the suite with --parallel and --coverage --min=80.

What it can do on your machine

Read from SKILL.md and the folder at commit 459bcd0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • Write
    • Edit
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    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

TDD With Pest loads about 526 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 221 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~526

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Glob, Grep, Write, Edit, Bash

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.

Tdd With Pest (Symfony)

Use when

  • Driving a feature with RED-GREEN-REFACTOR in a project that runs Pest v4 (PHP 8.3+).
  • Writing it() and expect() tests that need the Symfony kernel or an HTTP client.
  • Converting existing PHPUnit class tests to Pest syntax with pest-plugin-drift.
  • Adding a bug-reproducing test to a Pest suite before the fix.

Default workflow

  1. Confirm PHP 8.3+ and Pest v4, then generate tests/Pest.php with ./vendor/bin/pest --init.
  2. Bind the bridge classes in tests/Pest.php: uses(KernelTestCase::class, Factories::class, ResetDatabase::class)->in('Integration') and uses(WebTestCase::class, ...)->in('Functional').
  3. RED: write an it() test with Foundry v2 factories, run ./vendor/bin/pest --filter and check it fails for the right reason.
  4. GREEN: write the minimal code, then REFACTOR and re-run ./vendor/bin/pest.
  5. Gate the suite with --parallel and --coverage --min=80.

Guardrails

  • There is no official Symfony Pest plugin: never reference pestphp/pest-plugin-symfony, bind KernelTestCase or WebTestCase through uses().
  • Foundry v2 factories return real objects: no ->object() call.
  • Pest test files are anonymous, so use the Factories and ResetDatabase traits rather than the #[ResetDatabase] attribute.
  • Chain related checks with expect()->and(); keep one concept per test.

Progressive disclosure

  • Use this file for execution posture and risk controls.
  • Open references when deep implementation details are needed.

Output contract

  • The failing ./vendor/bin/pest output (RED), then the passing run.
  • tests/Pest.php bindings added or changed.
  • Test files changed and the commands executed.
