Mockito stubbing returning null when any Any arguments are used for method

I have the below method which I want to sub:

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

In my test class I have below

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);

However in this test productsArray returns as null;

Mockito gives the below warning

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

What could be the reason for this?

Edit:

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;
}

  • Edit after the first comment - I see that you call the method getProductsArrayForTest() while you define getProductsArrayTest(). Check if it is only a mistake in the post or even in the code. However here is the code and the test succeeds.

    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;
 }
}

    ProductTest.class

    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;
 }

}
