Unit testing custom action filter

Question

I have created a custom action filter (attribute) that hits a database. How can I unit test the controller actions by injecting a mock repository (so that it doesn't actually hit the database for the unit test) for the action filter to use?

Answer 1

I had the same question a couple of weeks ago.

At the end I accepted that I have to test the controller without the filter and test the filter itself.

Answer 2

Thanks for the info but it does not explain how the action filter can work with a mock repository that I can inject from the unit test.
