| @Test | テストメソッドであることを示す |
| @Test(timeout=1000) | 1000msたってもテストメソッドが終わらない場合には、失敗と見なす |
| @Test(expected = NullPointerException?.class) | NullPointerException?が起きることを期待する |
| @Ignore | 無視するテストメソッドであることを示す |
| @Before | それぞれのテストメソッド実行前に実行されるメソッド。わかりやすいように setUp() とする |
| @After | それぞれのテストメソッド実行後に実行されるメソッド。わかりやすいように tearDown() とする |
| @BeforeClass? | テストバッチの最初に一回だけ実行されるメソッド |
| @AfterClass? | テストバッチの最後に一回だけ実行されるメソッド |
