无法弄清楚JUnit测试用例失败的原因

Question

我必须修改我的类，以便它通过我教授给我们的一堆JUnit测试用例。我已经移动了一些东西，以便变量应该更早地给出它们的正确值，但它仍然没有测试用例。我不知道该改变什么，所以它通过了。

这是一个测试用例类，我在所有6个测试中都失败了

package dayofweektesting;

import dayofweek.DayOfWeek;
import static org.junit.Assert.*;
import org.junit.Test;

/**
 * Test cases for "Day of week" lab assuming requirements set 
 * at top of DayOfWeek class
 * 
 * Test valid leap years
 * 
 *
 */
public class TestValidLeapYears {

    /**
     * Test valid 2/29/XXXX dates
     */
    @Test
    public void firstValidLeapYear() {
        DayOfWeek dow = new DayOfWeek(2, 29, 1904);
        assertTrue(dow.getDayOfWeek().compareTo("Monday") == 0);
        assertTrue(dow.getNumericDayOfWeek() == 2);
    }

    @Test
    public void secondValidLeapYear() {
        DayOfWeek dow = new DayOfWeek(2, 29, 1908);
        assertTrue(dow.getDayOfWeek().compareTo("Saturday") == 0);
        assertTrue(dow.getNumericDayOfWeek() == 0);
    }

    @Test
    public void thirdValidLeapYear() {
        DayOfWeek dow = new DayOfWeek(2, 29, 1912);
        assertTrue(dow.getDayOfWeek().compareTo("Thursday") == 0);
        assertTrue(dow.getNumericDayOfWeek() == 5);
    }

    @Test
    public void fourthValidLeapYear() {
        DayOfWeek dow = new DayOfWeek(2, 29, 1916);
        assertTrue(dow.getDayOfWeek().compareTo("Tuesday") == 0);
        assertTrue(dow.getNumericDayOfWeek() == 3);
    }

    /**
     * Test boundary dates of2/28/XXXX and 3/1/XXXX for valid leap years
     */
    @Test
    public void firstValidLeapYearBoundaries() {
        DayOfWeek dow = new DayOfWeek(2, 28, 1904);
        assertTrue(dow.getDayOfWeek().compareTo("Sunday") == 0);
        assertTrue(dow.getNumericDayOfWeek() == 1);
        dow = new DayOfWeek(3, 1, 1904);
        assertTrue(dow.getDayOfWeek().compareTo("Tuesday") == 0);
        assertTrue(dow.getNumericDayOfWeek() == 3);
    }

    @Test
    public void secondValidLeapYearBoundaries() {
        DayOfWeek dow = new DayOfWeek(2, 28, 1908);
        assertTrue(dow.getDayOfWeek().compareTo("Friday") == 0);
        assertTrue(dow.getNumericDayOfWeek() == 6);
        dow = new DayOfWeek(3, 1, 1908);
        assertTrue(dow.getDayOfWeek().compareTo("Sunday") == 0);
        assertTrue(dow.getNumericDayOfWeek() == 1);
    }

}

这是我必须修改的课程，以便传递所有内容

public class DayOfWeek1 {
    int myMonth, myDayOfMonth, myYear, myAdjustment, numericDayOfWeek, remainderSeven;
    /*
     * @param what the date was
     */

        myMonth = month;
        myDayOfMonth = dayOfMonth;
        myYear = year;
        remainderSeven = 0;
        if(myMonth==1){
            myAdjustment = 1;
            if(myYear%4==0){
                myAdjustment=0;
            }
        }
        if(myMonth==2){
            myAdjustment = 4;
            if(myYear%4==0){
                myAdjustment=3;
            }

        remainderSeven = numericDayOfWeek % 7;
    }

        return remainderSeven;

你还没有指定你的JUnit测试会抛出什么错误，但我不得不猜测你猜错的原因是你使用DayOfWeek1作为你的类，你的JUnit测试正在测试一个类叫DayOfWeek。
