Using JustMock, how can I test if a method was called twice with different objects passed into it?

I have a piece of logic which is inserting a Product Model into a repository. The piece of logic will be inserting two product models both with different data into the repository and I need to test that this method is only called twice, once for each product.

public interface IProductRepo
{
    void AddProduct(IProductModel productModel);
}

public class ProductFactory
{
    IProductRepo productRepository;

    public ProductFactory(IProductRepo productRepo)
    {
        this.productRepository = productRepo;
    }

    public void AddProduct(IProductModel productModel)
    {
        this.productRepository.AddProduct(productModel);
    }
}

[TestMethod]
public void test()
{
    IProductModel productOne = Mock.Create<IProductModel>();

    Mock.Arrange(() => productOne.Name).Returns("ProductOne");
    Mock.Arrange(() => productOne.Price).Returns(99);

    IProductModel productTwo = Mock.Create<IProductModel>();

    Mock.Arrange(() => productTwo.Name).Returns("ProductTwo");
    Mock.Arrange(() => productTwo.Price).Returns(10);

    IProductRepo productRepo = Mock.Create<IProductRepo>();

    ProductFactory factory = new ProductFactory(productRepo);

    factory.AddProduct(productOne);
    factory.AddProduct(productTwo);

    // Test to see that both of these products being added called the IProductRepo.AddProduct() method.
}

UPDATE

based on comments, then you can call the assert twice. Once for each model.

Mock.Assert(() => productRepo.AddProduct(productOne), Occurs.Once());
Mock.Assert(() => productRepo.AddProduct(productTwo), Occurs.Once());

The assert would compare the args provided for equality when making the assertion.

Original answer

Referencing Asserting Occurrence from documentation,

consider using...

Mock.Assert(() => productRepo.AddProduct(Arg.Any<IProductModel>()), Occurs.Exactly(2));

in the minimal example provided above,

to see that both of these products being added called the IProductRepo.AddProduct() method.
