Mocking the behaviour of operators in Moq C#

Question

Hope your well.

I am in the process of creating some tests using Moq in C#. One of the objects I am Mocking has overridden ==, > and < operators.

Does anyone know if its possible, and if so how to... configure a Mock object to replicate this. The reason I ask is that I am trying to inject a mocked stub as some legacy code I have been given that has deep and dirty dependencies.

Your time is appreciated

Thanks

When you override such operations you should also provide theirs named equivalents too. If you rework yours code in such way it will be easier to mock it.

public static bool operator ==(SomeType a, SomeType b)
{
    return a.Equals(b);
}

public virtual bool Equals(SomeType b)
{
   // yours logic here
   return base.Equals(b)
}
