题目描述:

把计算模块提取出来,单独创建一个类。
针对提取出来的计算类的接口函数做单元测试。

单元测试代码:

 CalcTest.java

	int[] x = {3,4};
	int[] y = {5,9};
	int[] z = {3,0};
	
	
	@Before
	public void setUp() throws Exception {
	}

	@After
	public void tearDown() throws Exception {
	}

	@Test
	public void testCalc() {
		Calc c = new Calc();
	}

	@Test
	public void testPlusIntInt() {
		Calc.plus(2, 3);
		Calc.plus(5, 0);
		Calc.plus(2, 7);
	}

	@Test
	public void testSubtractIntInt() {
		Calc.subtract(2, 3);
		Calc.subtract(5, 0);
		Calc.subtract(2, 8);
	}

	@Test
	public void testMultiplyIntInt() {
		Calc.multiply(2, 3);
		Calc.multiply(5, 0);
		Calc.multiply(4, 8);
	}

	@Test
	public void testDivide() {
		Calc.divide(x, y);
		Calc.divide(z, y);
		Calc.divide(x, z);
	}

	@Test
	public void testYuefen() {
		Calc.yuefen(x);
		Calc.yuefen(y);
		Calc.yuefen(z);
	}

	@Test
	public void testCreate() {
		Calc.create();
	}

	@Test
	public void testPlusIntArrayIntArray() {
		Calc.plus(x, y);
		Calc.plus(x, z);
		Calc.plus(y, z);
	}

	@Test
	public void testSubtractIntArrayIntArray() {
		Calc.subtract(x, y);
		Calc.subtract(y, z);
		Calc.subtract(x, z);
	}

	@Test
	public void testMultiplyIntArrayIntArray() {
		Calc.multiply(x, y);
		Calc.multiply(x, z);
		Calc.multiply(y, z);
	}

	@Test
	public void testDivide2() {
		Calc.divide2(x, y);
		Calc.divide2(x, z);
		Calc.divide2(y, z);
	}

	@Test
	public void testJustify() {
		Calc.justify(x);
		Calc.justify(y);
		Calc.justify(z);
	}
 

	 
//
//	@Test
//	public void testGenerate() {
//		Calc.generate();
//	}

	@Test
	public void testNumber() {
		Calc.Number(50);
	}

	@Test
	public void testOperatorGenerate() {
		Calc.operatorGenerate(50);
	}

  CalcFunction.java

public class CalcFunctionTest {
	static int N = 6;
	static String[] titles  ;		//存储题目
	static String[] answers ;		//存储答案
	static String[] yourAnswers  ;		//存储回答的答案
	CalcFunction a = new CalcFunction();
	@Before
	public void setUp() throws Exception {
		
	}

	@After
	public void tearDown() throws Exception {
	}

	

	@Test
	public void testGenerate() {
		a.generate(5);
	}

}

  代码测试截图:

eclemma代码覆盖结果:

实验小结:

1、在代码的部分条件语句分支还没有覆盖到,

2、之前都没有做过单元测试,做完之后才发现其实在很多函数有很多问题,比如generate()函数里有变量参数还需要定义,在调用函数时没有仔细去考虑是要定义为static还是用setter,getter调用,

3、单元测试让修改代码也更清楚,条理更清晰,能准确发现一些函数的毛病
