PHPUnitでProtectedなプロパティ、関数をテストする

Last updated at Posted at 2013-02-07

テスト対象コード

SampleClass.php
<?php

class SampleClass
{
    protected $foo = TRUE;

    protected function hoge()
    {
        return TRUE;
    }
}
  • hoge()がTRUEを返すことを検証したい
  • $fooがTRUEであることを検証したい

テストコード

SampleClassTest.php
<?php

require_once 'SampleClass.php';

class SampleClassTest extends PHPUnit_Framework_TestCase
{
    public function testAccessProtectedProperty()
    {
        $foo = self::getProperty('foo');
        $obj = new SampleClass();

        $this->assertTrue($foo->getValue($obj));
    }

    public function testAccessProtectedMethod()
    {
        $foo = self::getMethod('hoge');
        $obj = new SampleClass();

        $this->assertTrue($foo->invokeArgs($obj, array()));
    }

    protected static function getProperty($name)
    {
        $class = new ReflectionClass('SampleClass');

        $property = $class->getProperty($name);
        $property->setAccessible(true);

        return $property;
    }

    protected static function getMethod($name)
    {
        $class = new ReflectionClass('SampleClass');

        $method = $class->getMethod($name);
        $method->setAccessible(true);

        return $method;
    }
}
