Java软件测试

Question

我正在为本周即将到来的考试复习，使用以前的试题，我只是不能得到100%的覆盖率，我的程序是：

public int computeInsurance(boolean SportsEquipment, boolean MusicEquipment)
{
int insurance;
if(SportsEquipment == true && MusicEquipment==true)
insurance = 20;
else if((SportsEquipment == true && MusicEquipment == false)||(SportsEquipment == false        && MusicEquipment == true))
        insurance = 10;
    else
        insurance= 5;

    return insurance;
}

}

我正在使用以下测试用例：

public class Lab5CarTest {

@Test
public void testComputeInsurance() {
    Lab5Car t = new Lab5Car();

    int result = t.computeInsurance(true, true);
    assertEquals(20,result);

    int i = t.computeInsurance(true,false);
    assertEquals(10,i);

    int u = t.computeInsurance(false,false);
    assertEquals(5,u);


}

}

但是我在代码的else if行中缺少了8个分支中的3个！

Answer 1

你为什么不测试一下：

int ip = t.computeInsurance(false,true);
assertEquals(10,ip);

像这样，你应该涵盖所有的内容。

您可以像这样简化代码：

if (SportsEquipment && MusicEquipment)
    insurance = 20;
else if (SportsEquipment != MusicEquipment)
    insurance = 10;
else
    insurance= 5;

Answer 2

1/4 (=2²)您缺少(不是2³)，t.computeInsurance(false, true);

S M  I
------
t t 20
t f 10
f t 10
f f  5


if (SportsEquipment  && MusicEquipment)
    insurance = 20;
else if (SportsEquipment != MusicEquipment)
    insurance = 10;
else
    insurance= 5;
