$answer = 1 + 1;
$this->assertIsInt($answer);
$this->assertIsNotFloat($answer);
$this->assertIsNumeric($answer);
$this->assertEquals($answer,2);
$this->assertNotEquals($answer, 100);
$this->assertGreaterThan($answer, 5);
$this->assertGreaterThanOrEqual($answer, 2);
$this->assertLessThan($answer, 1);
$this->assertLessThanOrEqual($answer, 2);

boolean関連

$this->assertIsBool(true);
$this->assertIsBool(false);
$this->assertTrue(true);
$this->assertFalse(false);

Null関連

$this->assertNull(null);
$this->assertNotNull(!null);

配列関連

$users = ['konan', 'sherry', 'ran', 'jin'];
$this->assertIsArray($users);
$this->assertCount(4, $users);
$this->assertNotCount(0, $users);
$this->assertContains('konan', $users);
$this->assertNotContains('kogoro', $users);
$this->assertNotEmpty($users);

$user = ['name' => 'konan', 'age' => 6];
$this->assertArrayHasKey('name', $user);
