When using Ninject for dependeny injection is it best practices to use Ninject in your unit tests or use a mocking framework

I am using ninject to inject dependencies in my production environment. I see two options when it comes to writing unit tests. I can either create concrete classes and inject them using ninject, Or I can use a mocking framework like just mock.

My thought process is to just use both and have the deciding factor be whether or not the TestInterface can be constructed in a reusable way. This way we dont waste time writing the same Mocked method to return an empty list over and over again.

Is there a best practice for this type of thing?
