Unable to Globally Mock Constructors

[ghost]

We are attempting to create a global mock that will allow us to mock a constructor. We have a wrapper service of a third party library and we want to just verify that our service is calling the third party constructor appropriately.

We need to do this as the third party has validation and other logic that takes place in their constructor and we don't want to have to rely on that for our unit tests.

So far we have gone through most (if not all) of the patterns on creating global mocks but we don't seem to be able to get anything working. We don't know if this is even possible (we haven't seen an example of mocking constructors) but it seems like it should be.

Are there any examples on this?
