I'm trying to do an assertException test on JUnit but my test keeps failing

so I'm currently learning on how to do better test cases on JUnit. So, I'm trying to test for an exception on my addItem() method, but the test keeps failing, and I don't know if maybe it has something to do with the model's if statement or maybe I'm just using the assertException() wrong

Here is the model code:

    package com.csis3275.model;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

public class MiniBar {

    private int itemCapacity;
    private String roomNo;
    private List<MiniBarItem> items = new ArrayList<>();
    
    public MiniBar(String assignedRoomNo, int newBarCapacity)   {
        this.itemCapacity = newBarCapacity;
        this.roomNo = assignedRoomNo;
    }
    
    //Add an item
    public void addItem(MiniBarItem newItem) {
        
        try {
            //Check the capacity
            if (items.size() == this.itemCapacity)  {
                throw new Exception("The bar is full!");
            } else {
                //Add the item
                items.add(newItem);
            }
        } catch (Exception barFull) {
            System.out.println(barFull.getMessage());
        }
        
    }
    
    //Remove and Item
    public MiniBarItem removeItem(MiniBarItem itemToRemove) {
        
        MiniBarItem itemToReturn = new MiniBarItem();
        try {
            if (items.size() != 0)  {
                for (MiniBarItem barItem : this.items)  {
                    if (itemToRemove.getName() == barItem.getName())    {
                        return barItem;
                    }
                }       
            } else {
            throw new Exception("The bar is empty!");
            }
            
        } catch (Exception barEmpty)    {
            System.out.println(barEmpty.getMessage());
        }
        return null;
        
    }
    
    //List Items that are expired
    public List<MiniBarItem> expiredItems (){
        List<MiniBarItem> expiredItems = new ArrayList<>();
        Date currentDate = new Date();
        System.out.print(currentDate);
        for (MiniBarItem item : this.items) {
            if (item.getBestBeforeDate().after(currentDate) ) {
                expiredItems.add(item);
                System.out.println("Added item: " + item);
                
            }
            else {
                System.out.println("No expired Items on list");
            }
        }
        return expiredItems;
    }
    //Produce a bill
    
}

And here is the test

class MiniBarIntegrationTest {
MiniBar myBar;
    List<MiniBarItem> testItems; 
    
    @BeforeEach()
    void init(){
        myBar = new MiniBar("208", 12 );
        testItems = new ArrayList<>();
        testItems.add(new MiniBarItem("Cookie", 19, new Date(2020, 03, 12)));
        testItems.add(new MiniBarItem("Water", 20, new Date(2021, 03, 12)));
        testItems.add(new MiniBarItem("Coke", 21, new Date(2020, 12, 12)));
        testItems.add(new MiniBarItem("Munchies", 23, new Date(2022, 03, 12)));
        testItems.add(new MiniBarItem("Weed", 27, new Date(2019, 03, 12)));
        testItems.add(new MiniBarItem("Beer", 19, new Date(2020, 11, 12))); 
        
        for(MiniBarItem b : this.testItems ) {
            myBar.addItem(b);
        }
        
        
    }

    @Test
    void testAddItemsToFullList() {
        List<MiniBarItem> testItems1 = new ArrayList<>(); 

        testItems1.add(new MiniBarItem("6", 19, new Date(2020, 03, 12)));
        testItems1.add(new MiniBarItem("7", 20, new Date(2021, 03, 12)));
        testItems1.add(new MiniBarItem("8", 21, new Date(2020, 12, 12)));
        testItems1.add(new MiniBarItem("9", 21, new Date(2020, 12, 12)));
        testItems1.add(new MiniBarItem("10", 21, new Date(2020, 12, 12)));
        testItems1.add(new MiniBarItem("11", 21, new Date(2020, 12, 12)));
        
        
        
        
        
        for(MiniBarItem b :testItems1 ) {
            myBar.addItem(b);
        }
        
        assertThrows(Exception.class, 
                ()->myBar.addItem(new MiniBarItem("Weed", 27, new Date(2019, 03, 12))));
        
        
        
    }

}

I'm getting this error on JUnit
