phpunit のメモ

繰り返しのテスト

@dataProvider

/**
 * @dataProvider testData
 * @params int  $year1
 * @params int  $year2
 * @params bool $expected
 */
public function testGroupNameValidate($year1, $year2, $expected)
{
    $this->assertSame($expected, $year1 === $year2);
}

public function testData()
{
    return [
        [2022, 2022, true],
        [2022, 2023, false],
        ...
    ];
}

繰り返しが少なければ

@testWith

/**
 * @testWith [2022, 2022, true]
 *           [2022, 2023, false]
 */
public function testGroupNameValidate($year1, $year2, $expected)
{
    $this->assertSame($expected, $year1 === $year2);
}

例外のテストで例外発生後にDBチェックとか別のアサートしたい

try~catch と assertInstanceOf()　で例外を検証すればよい

try {​
    $class->execute();
    $this->fail('例外発生なし');
}​ catch (\Exception $e) {​
    $this->assertInstanceOf('App\Exceptions\CustomException', $e);
    $this->assertEquals($expectedMsg, $e->getMessage());
}​
