I'm starting out in my Kentico developer journey and creating an MVC site. I wish to write unit tests against my Builder classes but they rely upon auto-generated provider classes that come out of Kentico. It seems as if the Kentico.Libraries.Tests package will not work with auto-generated provider classes or types. Does anyone know if this is possible?
I'm following the example shown here : https://docs.kentico.com/k11/custom-development/writing-automated-tests/faking-info-and-provider-objects-in-unit-tests
But not getting very far...due to an exception, that is causing me some confusion. The code :
Fake<HomePage,HomePageProvider>();
throws an exception of:
The type 'CMS.DocumentEngine.Types.HomePage' cannot be used as type
parameter 'TInfo' in the generic type or method
'AutomatedTestsWithData.Fake<TInfo, TProvider>(TProvider, bool)'.
There is no implicit reference conversion from
'CMS.DocumentEngine.Types.HomePage'
to
'CMS.DataEngine.AbstractInfoBase<CMS.DocumentEngine.Types.HomePage>'.
The HomePage Class looks like:
//--------------------------------------------------------------------------------------------------
// <auto-generated>
//
// This code was generated by code generator tool.
//
// To customize the code use your own partial class. For more info about how to use and customize
// the generated code see the documentation at http://docs.kentico.com.

Might want to look at how they did the tests for the MVC project on GitHub here and see if it helps.
