  • Mocking Non-Virtual Methods and Properties Overview

    Mocking non-virtual methods and non-abstract classes means that you can mock a concreate instance of whichever class you like. JustMock allows you to create any mock object and test your code in complete isolation from its dependencies to achieve the best possible design for your software without making any sacrifices.

    public class Context
    

    {
    

        public IList<int> myList = new List<int>();
    

     
    

        public void PopulateList(int count)
    

        {
    

            for (int i = 0; i < count; i++)
    

            {
    

                this.myList.Add(i);
    

            }
    

        }
    

    }

    [TestMethod]
    

    public void MockConcreteInstance_And_ValidateOccurance()
    

    {
    

        var expectedOccurrences = 10;
    

     
    

        // ARRANGE
    

        // Creating a mock instance of the "Context" class with Behavior.CallOriginal.
    

        var foo = Mock.Create<Context>(Behavior.CallOriginal);
    

     
    

        // Arranging: foo.myList.Add() should be called expected number of times no matter the argument.
    

        Mock.Arrange(()=> foo.myList.Add(Arg.AnyInt)).Occurs(expectedOccurrences);
    

     
    

        // ACT
    

        foo.PopulateList(expectedOccurrences);
    

     
    

        // ASSERT
    

        Mock.Assert(foo);
    

    }
