Cannot mock IUpdateEntityRequestBuilder<TEntity>

[baynezy]

I am trying to mock an UpdateItem<TEntity> to unit test my code. I am following the approach you use in this example. However, it gets very bent out of shape with IUpdateEntityRequestBuilder<TEntity>.

Example

var builderMock = Substitute.For<IUpdateEntityRequestBuilder<object>>();

I get an error:

System.TypeLoadException
Method 'Create' in type 'Castle.Proxies.ObjectProxy_2' from assembly 'DynamicProxyGenAssembly2, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

Which I have also raised on the NSubstiture repo. nsubstitute/NSubstitute#866 I have tried the same thing with Moq and I get the same issue. So it is likely a Castle.Core + EfficientDynamoDb compatibility issue.

In this comment @firenero states that:

EfficientDynamoDb calls are mockable by design

Is this still the case? Am I doing something wrong?

Thanks for reporting it @baynezy. The issue happens because of the internal method in IUpdateEntityRequestBuilder. We should add default implementation to this method similarly to IGetItemEntityRequestBuilder/ITableBuilder. It also makes sense to verify that other interfaces are not affected by similar issues and address all of them in a single PR.

I think I can look into it in the next few days. Or you can submit a PR if you want to get this change merged faster.

Thanks @firenero - I see you have begun this work. Much appreciated.
