1、修正流程图

 

2、测试用例设计

3、单元测试框架

 

import static org.junit.Assert.*;

import org.junit.Before;
import org.junit.Test;

public class CommissionTest {
	Commission commission = new Commission();
	@Before
	public void setUp() throws Exception {
	}

	@Test
	public void testMain() {
		
	assertEquals(29.2,commission.commission(2, 6, 9),0.0001);
        assertEquals(-1,commission.commission(-2,6,9),0.0001);    
        assertEquals(161.8,commission.commission(16, 6, 9),0.0001);
        assertEquals(145.0,commission.commission(15, 6, 5),0.0001);
        assertEquals(405.2,commission.commission(30, 15, 22),0.0001);
	    }
	}

　　

4、测试结果

 

5、测试小结

单元测试可以很快的验证测试代码的正误，以后编写代码时要养成单元测试的习惯。
