  • SKILL.md covers Priority: P1 (HIGH), Core Rule Anchors, Write Tests with PHPUnit and… and Anti-Patterns, plus 2 more sections

What it does

Php Testing is an agent skill from HoangNguyen0403/agent-skills-standard. Write unit and integration tests for PHP applications with PHPUnit and Pest. Use when writing PHPUnit unit tests or integration tests for PHP applications.

Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/implementation.md`).

It sits in Testing & QA, covering Integration testing and Unit testing. It works with PHP. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Writing PHPUnit unit tests
  • Integration tests for PHP applications

Example prompts

  • “/php-testing”

What it can do on your machine

Read from SKILL.md and the folder at commit 266fd75. 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

    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

Php Testing loads about 929 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 393 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~929
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

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.

PHP Testing

Priority: P1 (HIGH)

Core Rule Anchors

  • [BE-TEST-01] Parameterized Tests for Equivalent Cases: Prefer #[DataProvider] (PHPUnit) or dataset (Pest) when methods have multiple equivalent inputs or boundary permutations. Distinct scenarios may stay separate test methods. Reviewers must not demand parameterized rewrites without a behavioral gap.
  • [BE-TEST-02] Ban on Brittle DB Mock String Matching: Do not use string-matching mocks for raw SQL queries. Test pure domain calculations directly, or use SQLite in-memory / real DB for database repository verification.
  • [BE-TEST-03] Ban on Shallow Assertions: Never assert only assertNotNull($result) without inspecting domain fields, status codes, and invariants.
  • [BE-TEST-04] Ban on Pass-Through Interface Mocks: Repositories and service handlers must test contract compliance and error mapping. Ban 1:1 pass-through mock echoing without contract assertions.
  • [BE-TEST-05] Bug-First Regression Lock: Every PR fixing a bug ticket or with title fix(...) must introduce a test reproducing the defect prior to the fix.

Write Tests with PHPUnit and Pest

  • Standards: Use PHPUnit (9/10+) or Pest. Organize into Unit/, Integration/, and Feature/. Class names should extend TestCase.
  • TDD Workflow ([BE-TEST-05]): Follow Red-Green-Refactor. Write failing test first, implement minimal logic, then refactor.
  • Fluent Assertions ([BE-TEST-03]): Use assertSame (===) over assertEquals to avoid type coercion. Also use assertCount() and assertMatchesRegularExpression(). Avoid shallow assertions.
  • Data Providers ([BE-TEST-01]): Use #[DataProvider('statusProvider')] (PHPUnit 10+) or dataset (Pest).
  • Mocking & Isolation ([BE-TEST-02], [BE-TEST-04]): Use createMock() for dependencies; ban 1:1 pass-through mock echoing. Ensure tests are independent and repeatable. DB tests must use Transactions or SQLite :memory:.
  • Coverage: Coverage is diagnostic and project-configured; verify risk-weighted critical paths rather than padding code for an arbitrary percentage.

Anti-Patterns

  • [BE-TEST-01] Stylistic parameterized rewrites: Do not demand data provider rewrites without a behavioral gap.
  • [BE-TEST-02] Brittle DB mock string matching: Do not match SQL strings in mocks.
  • [BE-TEST-03] Shallow assertions: Never assert only assertNotNull without domain payload checks.
  • [BE-TEST-04] Pass-through mock echoing: Ban 1:1 mock echoing without contract assertions.
  • [BE-TEST-05] Bug fix without reproduction test: Ban bug fixes without a reproduction test.
  • No testing private methods: Test through public interfaces only.
  • No over-mocking internals: Mock only external boundaries.
  • No real network/DB in unit tests: Use in-memory databases or mocks.
  • No coverage-metric chasing: Prioritize meaningful assertions over arbitrary percentage metrics.
