C# – Moq mock method with out specifying input parameter

cmockingmoq

I have some code in a test using Moq:

public class Invoice
{
    ...

    public bool IsInFinancialYear(FinancialYearLookup financialYearLookup)
    {
        return InvoiceDate >= financialYearLookup.StartDate && InvoiceDate <= financialYearLookup.EndDate;
    }
    ...
}

So in a unit test I'm trying to mock this method and make it return true

mockInvoice.Setup(x => x.IsInFinancialYear()).Returns(true);

Is there anyway to write this line so I don't have to specify the input to IsInFinancialYear. ie. So that it doesn't in the code what the input parameter is it will return true whatever is passed to it?

Best Answer

You can use It.IsAny<T>() to match any value:

mockInvoice.Setup(x => x.IsInFinancialYear(It.IsAny<FinancialYearLookup>())).Returns(true);

See the Matching Arguments section of the quick start.
