这显示了具有要引用的属性的类 https://stackoverflow.com/posts/comments/65623190?noredirect=1
Product.class
@Override
public int compareTo(Goods o) {
int compared = 0;
System.out.println("Date " + o.getDate() + " " + this.getDate());
if(o.getDate() != this.getDate()) {
compared = 1;
}
System.out.println("Price " + o.getPrice() + " " + this.getPrice());
if(Double.compare(o.getPrice(), this.getPrice()) != 0) {
compared = 1;
}
System.out.println("Status " + o.getStatus() + " " + this.getStatus());
if(o.getStatus() != this.getStatus()) {
compared = 1;
}
System.out.println("Name " + o.getProductName() + " " + this.getProductName());
if(o.getProductName() != this.getProductName()) {
compared = 1;
}
if(o.getDate().equals(this.getDate()) &&
o.getStatus().equals(this.getStatus()) &&
o.getProductName().equals(this.getProductName()) &&
o.getPrice().equals(this.getPrice())) {
compared = 0;
}
return compared;
}
JunitTest.class
@Test
public Test {
Product product = new Product();
product.setProductName("Product_A");
product.setPrice(4.10);
product.setStatus(Library.STATUSES.THEM);
calendar.set(Calendar.MONTH, Calendar.AUGUST);
date = calendar.getTime();
product.setDate(date);
actualGoods.add(product);
product = new Product();
product.setProductName("Product_A");
product.setPrice(3.70);
product.setDate(date);
product.setStatus(Library.STATUSES.HIM);
expectedGoods.add(product);
assertSame(expectedGoods, classLib.ProductUpdate(actualGoods, Library.STATUSES.HIM));
}
然后我的方法取代了更便宜的产品,并将状态转换为我的图书馆类中的“HIM”状态
public List<Product> redLinePromotionListStatusUpdate(List<Product> actualProduct, STATUSES status) {
List<Product> currentProducts = new ArrayList<>();
List<Product> originalStatusProducts = new ArrayList<>();
int listIndex = 0;
if(actualProduct != null) {
for (Product product : actualProduct) {
if (product.getStatus().toString().equals(STATUSES.THEM.toString())) {
originalStatusProducts.add(listIndex, product);
listIndex++;
}
if (product.getStatus().equals(STATUSES.valueOf(status.toString())) && containsName(originalStatusProducts, product.getProductName())) {
if ((callReductionPrice(product.getPrice(), originalStatusProducts.get(originalStatusProducts.size() - 1).getPrice())) < originalStatusProducts.get(originalStatusProducts.size() - 1).getPrice()) {
currentProducts.add(product);
}
}
}
}
return currentProducts;
}
我得知我的两个对象并不相同。当我使用类方法compareTo时,我得到它们就是在某个地方我的Library类方法中失去了等价。
修改
java.lang.AssertionError:expected:&lt; [Goods @ 45322aea]&gt;但是:&lt; [Goods @ 149fac29]&gt; java.lang.AssertionError:期望的相同:&lt; [Goods @ 34c636a7]&gt;不是:&lt; [Goods @ 59797c7]&gt;
当我尝试assertTrue(object.equals(testObject))时,我得到了java.lang.AssertionError 的修改 调试预期Sun Aug 21 16:19:10 EDT 2016价格3.7状态HIM 名称Product_A 实际产品_A HIM 3.7 Sun 8月21日16:19:10 EDT 2016
Product_A REDLINE30 3.7来自预期对象的null Product_A REDLINE30 3.7来自实际对象的null
但我仍然得到AssertionError。 你知道如何从断言失败中获取对象的更多信息细节吗?
答案 0 :(得分:2)
Assert.assertSame
doc说:
Asserts that two objects refer to the same object.
两个对象可以相等(object1.equals(obejct2)
),而不是相同的参考。
