Java軟件測試

Question

我修改了測試使用以前的考題，我就不能得到100％的覆蓋率即將舉行的這一週，我的計劃是：

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; 
} 

} 

我使用下面的測試情況：

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); 


} 

} 

但是我錯過了3個分支中的8個，其他的如果我的代碼行！

Answer 1

你爲什麼不測試：

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

這樣你就應該涵蓋所有。

可以簡化你這樣的代碼：

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

Answer 2

1出4（= 2 2）你缺少（不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;
