Junit基础篇、中级篇实例代码,软件测试

  实例测试代码目录结构:

  Calculator.java:

1 public class Calculator{

2 private static int result;//静态变量,用于存储运行结果

3

4 public void add(int n){

5 result = result+n;

6 }

7

8 public void substract(int n){

9 result = result-1;//bug:之前应该是 result = result-n

10 }

11

12 public void multiply(int n){

13

14 }//此方法尚未写好

15

16 public void divide(int n){

17 result = result/n;

18 }

19

20 public void square(int n){

21 result = n*n;

22 }

23

24 public void squareRoot(int n){

25 for(;;){} //bug:死循环

26 }

27

28 public void clear(){

29 result = 0;

30 }

31

32 public int getResult(){

33 return result;

34 }

35 }

  CalculatorTest.java:

1 import static org.junit.Assert.*;

2

3 import org.junit.After;

4 import org.junit.Before;

5 import org.junit.Ignore;

6 import org.junit.Test;

7

8

9 public class CalculatorTest {

10

11 private static Calculator calculator = new Calculator();

12

13 @Before

14 public void setUp() throws Exception {

15 calculator.clear();

16 }

17

18 @After

19 public void tearDown() throws Exception {

20 }

21

22 @Test

23 public void testAdd() {

24 calculator.add(2);

25 calculator.add(3);

26 assertEquals(5,calculator.getResult());

27 }

28

29 @Test

30 public void testSubstract() {

31 calculator.add(10);

32 calculator.substract(2);

33 assertEquals(8,calculator.getResult());

34 }

35

36 @Ignore("Multiply() Not yet implemented")

37 @Test

38 public void testMultiply() {

39

40 }

41

42 @Test

43 public void testDivide() {

44 calculator.add(8);

45 calculator.divide(2);

46 assertEquals(4,calculator.getResult());

47 }

48

49 @Test(timeout = 1000)

50 public void squareRoot(){

51 calculator.squareRoot(4);

52 assertEquals(2,calculator.getResult());

53 }

54

55 @Test(expected = ArithmeticException.class)

56 public void divideByZero(){

57 calculator.divide(0);

58 }

59 }

  执行结果,"failure Trace"报错或运行失败原因:

  (1)squareRoot超时,报错

  (2)testSubstract用例失败

  (3)testMultiply忽略运行

  执行单个用例:

  选中用例,右键点击“Run”
