之前说过@Factory更适合于同一类型的參数变化性的測试，那么假设參数值没有特定的规律时，我们能够採用@Factory和@DataProvider相结合的方式进行測试

注意要点：请注意測试方法将被一共运行的次数。由于@Factory本身就属于循环測试的类型。@DataProvider也是属于測试总体循环的类型

		return result;
	}

	@DataProvider(name = "datasource")

public class TestngFactoryTest {
	private int m_numberOfTimes;

	public TestngFactoryTest(int numberOfTimes) {
		this.m_numberOfTimes = numberOfTimes;
	}

	private static int num;

	@Test
	public void testServer() {
		num++;
		System.out.println("num    " + num + "  m_numberOfTimes ："
				+ m_numberOfTimes);
	}
