🔌 Method Assertions

toHaveMethod()

$this
  ->allClasses()
  ->fromRaw('<?php class Foo { public function bar() {} }')
  ->should(fn(Expr $expr) => $expr->toHaveMethod('bar'));

toNotHaveMethod()

Opposite of toHaveMethod(). Fails if the resource declares the given method.

• Forbid magic accessors: toNotHaveMethod('__get').
• Keep Value Objects free of setters: toNotHaveMethod('setValue').

$this
  ->allClasses()
  ->fromDir('src/Domain')
  ->should(fn(Expr $expr) => $expr->toNotHaveMethod('__get'));

toHaveNoStaticMethod()

Fails for every static method declared by the resource, whatever its visibility. Static properties and static closures are not methods and are ignored.

Example: Forbid static constructors (make(), fromArray()…) on classes resolved by the container.

$this
  ->allClasses()
  ->fromDir('src/Domain/*/Action')
  ->should(fn(Expr $expr) => $expr->toHaveNoStaticMethod());

toHaveOnlyPrivateProperties()

Fails for every property that is not private: declared properties (static or not) and properties promoted by the constructor. One violation is reported per property, at its line.

$this
  ->allClasses()
  ->fromDir('src/Domain/*/Action')
  ->should(fn(Expr $expr) => $expr->toHaveOnlyPrivateProperties());

toHaveOnlyPublicMethods()

Fails for every public method whose name is not in the given list; private and protected methods are always allowed. Method names are compared case-insensitively, as in PHP.

Example: keep invokable classes focused: only __construct() and __invoke() are public.

$this
  ->allClasses()
  ->fromDir('src/Domain/*/Action')
  ->should(fn(Expr $expr) => $expr->toHaveOnlyPublicMethods(['__construct', '__invoke']));

toHaveOnlyPublicProperties()

Opposite constraint of toHaveOnlyPrivateProperties(): fails for every property that is not public, declared or promoted by the constructor. A promoted readonly property without visibility is public. Useful for DTOs built on public readonly properties.

$this
  ->allClasses()
  ->fromDir('src/Dto')
  ->should(fn(Expr $expr) => $expr->toHaveOnlyPublicProperties());

toHaveConstructor()

$this
  ->allClasses()
  ->should(fn(Expr $expr) => $expr->toHaveConstructor());

toNotHaveConstructor()

Opposite of toHaveConstructor(). Shortcut for toNotHaveMethod('__construct').

$this
  ->allClasses()
  ->fromDir('src/Enum')
  ->should(fn(Expr $expr) => $expr->toNotHaveConstructor());

toHaveDestructor()

$this
  ->allClasses()
  ->should(fn(Expr $expr) => $expr->toHaveDestructor());
