就如標題如果你既希望載入SpringContext跑整合測試，同時又希望使用JUnit的引數化方法跑基於資料的測試，該怎麼辦？@RunWith只允許你傳入一個Class型別。

下面是一個Spring官方例子告訴你怎麼實現：

根據我自己的業務需求，實現的類似的例子：

import org.springframework.test.context.web.WebAppConfiguration;

import java.util.List;

import static org.junit.Assert.assertEquals;

	}

	@Parameters
	public static List<Object[]> data() {
		return Lists.newArrayList(new Object[][]{
				{A14, A15, A14, A15, 7.06733840514568d}

	}

有人可能會說，這個是不是會影響速度，畢竟資料驅動，會跑的資料很多，我自己的測試還好，Spring的上下文在Class級別只加載一次，但是速度快慢還是取決於你的Service層或者Dao是否需要和資料庫打交道。
