对一段Java代码的单元测试

Posted 2020-08-08 星光漫过老树藤

  
public class Student  
{  
  
    private String name;  
    private String sex;  
    private int high;  
    private int age;  
    private String school;  
      
    public Student(String name, String sex ,int high, int age, String school)  
    {  
        this.name = name;  
        this.sex = sex;  
        this.high = high;  
        this.age = age;  
        this.school = school;  
    }  
    public String getName()  
    {  
        return name;  
    }  
    public void setName(String name)  
    {  
        this.name = name;  
    }  
    public String getSex()  
    {  
        return sex;  
    }  
    public void setSex(String sex)  
    {  
        this.sex = sex;  
    }  
    public int getHigh()  
    {  
        return high;  
    }  
    public void setHigh(int high)  
    {  
        this.high = high;  
    }  
    public int getAge()  
    {  
        return age;  
    }  
    public boolean setAge(int age)  
    {  
        if (age >25)  
        {  
            return false;  
        }  
        else  
        {  
            this.age = age;  
            return true;  
        }                 
    }  
      
  
    public String getSchool()  
    {  
        return school;  
    }  
    public void setSchool(String school)  
    {  
        this.school = school;  
    }  
      
} 

 

　　

在eclipse下单元测试这个类：  

首先导入Junit包：选中java工程，点击鼠标右键--->选择properties---->在窗口中选Java Build Path---->在右侧点击Add Library---->在弹出的窗口列表中选中Junit---->下一步----->Junit 4---->finish
