java - 当任何 Any 参数用于方法时，Mockito stub 返回 null

Question

我有以下我想要子的方法:

ProductArray productsArray;
productsArray = dataService.getProducts(ProductFilter pf, Date date1, Date date2, boolean matured);

在我的测试课中，我有以下内容

ProductArray productsArrayTest = getProductsArrayForTest();
Mockito.when(dataServiceMock.getProducts(Mockito.any(ProductFilter.class), Mockito.any(Date.class), Mockito.any(Date.class), Mockito.any(Boolean.class))).thenReturn(productsArrayTest);

但是在此测试中 productsArray 返回为 null;

Mockito 给出以下警告

[MockitoHint] 1. Unused... -> at 
com.company.util.TestProduct.testProductLoad(TestProduct.java:157)
[MockitoHint]  ...args ok? -> at 
com.company.datastore.ProductLoader.processAll(ProductLoaderProcess.java:158)

这可能是什么原因？

编辑:

private ProductArray getProductsArrayTest() {
    ProductArray pa = new ProductArray();
    Product product = createProduct();
    pa.add(product);
    return pa;
}

private Product createProduct() {
    Product p = new Product();
    p.setPrice(1.23);
    return p;
}

• 在第一条评论后编辑 -我发现您在定义 getProductsArrayTest() 时调用了 getProductsArrayForTest() 方法。检查是否只是帖子中的错误，甚至是代码中的错误。但是这里是代码并且测试成功。

  public class Product {
   double price;
   public Product() {
  
   }
   public double getPrice() {
    return this.price;
   }
   public void setPrice(double value) {
    this.price=value;
   }
  }
  

  ProductArray.class

  import java.util.ArrayList;
  import java.util.List;
  
  
  public class ProductArray {
   private List<Product> productList;
   public ProductArray() {
    productList=new ArrayList<Product>();
  
   }
   public void add(Product product) {
    this.productList.add(product);
   }
   public List<Product> getProductList(){
    return this.productList;
   }
  }
  

  产品测试.类

  public class ProductTest {
   @Test
   public void testProduct() {
    DataService dataserviceMock = Mockito.mock(DataService.class);
    ProductArray productsArrayTest = getProductsArrayTest();
    Mockito.when(dataserviceMock.getProducts(Mockito.any(ProductFilter.class), Mockito.any(Date.class), Mockito.any(Date.class), Mockito.anyBoolean())).thenReturn(productsArrayTest);
    assertEquals(1, dataserviceMock.getProducts(null , null , null , false).getProductList().size());
   }
   private ProductArray getProductsArrayTest() {
       ProductArray pa = new ProductArray();
       Product product = createProduct();
       pa.add(product);
       return pa;
   }
  
   private Product createProduct() {
       Product p = new Product();
       p.setPrice(1.23);
       return p;
   }
  
  }
