phpcs-aaa
=========

[](#phpcs-aaa)

PHP\_CodeSniffer standard that enforces the **Arrange-Act-Assert** pattern in PHP test methods.

> **Heads up:** if you are reading this on the `babu-ch/phpcs-aaa` repo, that is a **read-only split mirror** distributed via Packagist. Source, issues, and pull requests live in the parent monorepo: .

Install
-------

[](#install)

```
composer require --dev babu-ch/phpcs-aaa
```

If you are not using the [phpcodesniffer-composer-installer](https://github.com/PHPCSStandards/composer-installer), point PHPCS at the standard manually:

```
vendor/bin/phpcs --config-set installed_paths vendor/babu-ch/phpcs-aaa
```

Usage
-----

[](#usage)

Add to your `phpcs.xml.dist`:

```

    tests

```

Or run directly:

```
vendor/bin/phpcs --standard=AAA tests/
```

What it checks
--------------

[](#what-it-checks)

Every test method (name starting with `test` by default, per PHPUnit convention) must contain three marker comments in order:

```
public function testAdds(): void
{
    // arrange
    $a = 1;
    $b = 2;

    // act
    $sum = $a + $b;

    // assert
    $this->assertSame(3, $sum);
}
```

Configuration
-------------

[](#configuration)

Override properties in your ruleset:

```

```

Note: the `labels` property via XML only accepts scalar values per key. For multiple synonyms (e.g. Japanese `準備 / 前準備`), configure via a custom sniff subclass or a PHP-based ruleset at the moment.

### Given / When / Then

[](#given--when--then)

```

```

Auto-fix
--------

[](#auto-fix)

When **all three** section comments are missing, `vendor/bin/phpcbf` (the auto-fixer that ships with PHP\_CodeSniffer) inserts a `// arrange` / `// act` / `// assert` template at the top of the test method. You then move each comment above the code that belongs to it.

Other cases — one or two sections missing, wrong order, empty section — are reported with explicit hints in the error message but are not auto-fixed, because the correct insertion point depends on the test's intent.

Development
-----------

[](#development)

```
composer install
composer test
```

Tests use PHPUnit against the PHPCS Ruleset/DummyFile API directly (no fixture file dance).
