검증 (assertion)

이 절에서는 사용 가능한 검증 메소드들을 설명합니다.

assertArrayHasKey()

assertArrayHasKey(mixed $key, array $array[, string $message = ])

assertThat()

보다 복잡한 검증들이 PHPUnit_Framework_Constraint 클래스를 사용하여 만들어질 수 있습니다. 이렇게 만들어진 검증은 assertThat() 메소드를 사용하여 평가됩니다. 예4.55 는 logicalNot() 과 equalTo() 를 제약(constraint) 으로 사용하여 assertNotEquals()와 같은 검증을 만든 것입니다.

assertThat(mixed $value, PHPUnit_Framework_Constraint $constraint[, $message = ])

$value 가 $constraint 와 매치되지 않을 경우, 에러 $message 를 보고합니다.

예4.55: Usage of assertThat()

<?php
  class BiscuitTest extends PHPUnit_Framework_TestCase
{
  public function testEquals()
  {
    $theBiscuit = new Biscuit('Ginger');
    $myBiscuit = new Biscuit('Ginger');
    $this->assertThat(
		      $theBiscuit,
		      $this->logicalNot(
					$this->equalTo($myBiscuit)
					)
		      );
  }
