　　據Google結果，JUnit的參數化測試不被Spring 2.5的SpringJUnit4ClassRunner所支援，但仍有法可解，如下：

@RunWith(Parameterized.class)
@ContextConfiguration(locations= {"classpath*:resources/spring/**/*.xml"})
@TestExecutionListeners( {DependencyInjectionTestExecutionListener.class })
public class EmployeeDaoImplTest
{
    private final TestContextManager testContextManager;

    @Autowired
    private ApplicationContext applicationContext;

　@Autowired
    private EmployeeDao employeeDao;

    private final String cv_loginid;
    private final String cv_username;
    public EmployeeDaoImplTest(String cv_loginid, String cv_username) {
        this.testContextManager = new TestContextManager(getClass());
        this.cv_loginid = cv_loginid;
        this.cv_username = cv_username;
    }

    @Parameters
    public static Collection<String[]> employeeData() {
        return Arrays.asList(new String[][] {
        {"admin", "Administrator" },
        {"guest", "Guest"},
        {"test", "Tester"}});
    }

    @Before
    public void injectDependencies() throws Exception {
        this.testContextManager.prepareTestInstance(this);
    }

    @Test
    public void parameteriedTest() {
        assertEquals(this.cv_username, this.employeeDao.findByLoginId(this.cv_loginid).getCvUsername());
    }
}

　　這個作法其實在和JUnit 3.8.1差不多，紅字體是要改變的作法。在JUnit 3.8.1通常在setUp method去initialize Spring context，而這裡@Before就等同於setUp method，只是initialize Spring context工作變成由TestContextManager去做。

　　Parameteried的測試架構，看來是利用static會比new instance先執行的特性，取得@Parameters傳回的Collection之後，等於每一輪迭代都要初始化一次TestContext的instance，及傳Collection裡的參數給constructure，有點巨集(Macro)的味道。
