运行 JUnit 4 参数化测试时遇到障碍我是 JUnit 测试的新手

问题描述

我是 JUnit 测试的新手。我在这个参数化测试中遇到了一个问题，即使我尝试了一些方法，测试也总是失败。

 import java.util.ArrayList;

class Student {
    
    String name;
    int mark;
    
    public Student(String name,int mark) {
        this.name = name;
        this.mark = mark;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getMark() {
        return mark;
    }

    public void setMark(int mark) {
        this.mark = mark;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        Student other = (Student) obj;
        if (mark != other.mark)
            return false;
        if (name == null) {
            if (other.name != null)
                return false;
        } else if (!name.equals(other.name))
            return false;
        return true;
    }
}

public class CheckStudentClass {
    
    public Student[] checkForHighestMarks(int minMark,int numStudents,Student[] studArray) {

        ArrayList<Student> studList = new ArrayList<>();
        
        int currentHighestMark = 0;
        for (int i = 0; i < numStudents; i++) {
            if (minMark < studArray[i].getMark()) {
                if (currentHighestMark < studArray[i].getMark()) {
                    studList = new ArrayList<>();
                    currentHighestMark = studArray[i].getMark();
                    studList.add(studArray[i]);
                }
                else if (currentHighestMark == studArray[i].getMark()) {
                    studList.add(studArray[i]);
                }
            }
        }
        Student[] arrayToReturn = new Student[studList.size()];
        arrayToReturn = studList.toArray(arrayToReturn);
        return arrayToReturn;
    }

}

这是测试类：

package my.edu.utar;

import static org.junit.Assert.*;
import org.junit.runner.RunWith;
import junitparams.Parameters;
import junitparams.JUnitParamsRunner;
import org.junit.Test;

@RunWith(JUnitParamsRunner.class)
public class CheckStudentClasstest {

    @Test
    @Parameters(method = "marksData")
    public void testCheckForHighestMarks(int aMinMark,int aStudentNumber,Student[] aStudentArray,int expectedResult) {

        CheckStudentClass csc = new CheckStudentClass();
        
        Student[]  actualResult = csc.checkForHighestMarks(aMinMark,aStudentNumber,aStudentArray);
        assertEquals(expectedResult,actualResult);
    }
    
    

    public Object[] marksData() {
        return new Object[] {
                new Object[] {50,4,new Student[] {new Student("A",50),new Student("B",60),new Student("C",70),new Student("D",80)},80},new Object[] {50,new Student[] {new Student("E",new Student("F",new Student("G",new Student("H",60)},60}
        };
    }

}

测试结果如下：

第一个结果：

java.lang.AssertionError: expected:<80> but was:<Student;@78b729e6>

第二个结果：

java.lang.AssertionError: expected:<60> but was:<Student;@7692d9cc>

我现在很困惑这种结果是怎么发生的，请问您对解决这个问题有什么意见吗？
