java如何Junit测试默认构造函数？

Question

我如何单位这个构造函数

private Item[] items;

private int currentIndex;



/**
 * Default Constructor
 */
public Inventory() 
{
    this.items = new Item[1];
    this.currentIndex = 0;
}

Answer 1

将非公共测试成员和字段包私有化是标准做法。像这样,

Item[] items;
int currentIndex;

public Inventory() 
{
    this.items = new Item[1];
    this.currentIndex = 0;
}

现在只要单元测试与Inventory类在同一个包中

public void testCtor() {
 Inventory i = new Inventory();
 assertNotNull(i.items);
 assertEqual(1, i.items.length);
 assertEqual(0, i.currentIndex);
}
