NBuilder parameterless constructor error

Question

We are using NBuilder for generating test data for our tests. We have a few models with private setters. So setting thos properties is only possible throughout the constructor. The problem is that we get the following error from NBuilder:

CompanyAddressViewModel does not have a default parameterless constructor

I understand the error. Do I really need to create a default constructor in my class?

Here is my NBuilder code:

Builder<CompanyAddressViewModel>.CreateNew().Build()

Answer 1

You can use WithConstructor() or WithFactory() method, in Net Core 2.1 WithConstructor() method is deprecated.

Builder<CompanyAddressViewModel>.CreateNew(). WithFactory (() => new parameter()).Build()

Answer 2

Former versions uses WithConstructor() method, but it's obsolete in these days, so you should use WithFactory() method:

Builder<CompanyAddressViewModel>
         .CreateNew()
         .WithFactory(() => new CompanyAddressViewModel("your", "parameter"))
         .Build()
